A. Persons with history of:

  • Anaphylactic or allergic reaction to a previous dose of COVID-19 vaccine
  • Immediate or delayed-onset anaphylaxis or allergic reaction to vaccines or injectable therapies, pharmaceutical products, food-items etc.

B. Pregnant women: Regarding COVID-19 Vaccination of pregnant women, the matter is under discussion in India. Pregnant women have not been part of any COVID-19 vaccine clinical trial so far. Therefore, women who are pregnant or not sure of their pregnancy; should not receive COVID-19 vaccine at this time

C. Provisional / temporary contraindications: In these conditions, COVID-19 vaccination is to be deferred after recovery

  • Individuals having lab test proven SARS-2 COVID-19 infection: COVID-19 vaccine to be deferred by 3 months after recovery.
  • SARS-2 COVID-19 patients who have been given anti-SARS-2 monoclonal antibodies or convalescent plasma: COVID-19 vaccine to be deferred by 3 months from the date of discharge from the hospital.
  • Individuals who have received at least the 1 st  dose and got COVID-19 infection before completion of the dosing schedule: the 2 nd  dose should defer the COVID-19 vaccine by 3 months after clinical recovery from COVID-19 illness.
  • Persons with any other serious general illness requiring hospitalization or ICU care should also wait for 4-8 weeks before getting the COVID-19 vaccine.

D. Other health Conditions :

  • Individuals with bleeding disorders like ‘haemophilia’ should take the vaccine under the supervision of their treating physician.
  • Individuals with heart and brain disorders are on blood thinners like aspirin and antiplatelet drugs can continue with their medicines and have the vaccines. They should also consult their physician. For them, vaccines are absolutely safe.
  • One should inform the vaccinator about the medicines they consume and if they are suffering from any known immune issues. The vaccinator should have a record of one’s medical condition.

Two vaccines have been approved for Emergency Use Authorisation (EUA) by the National Regulator i.e. Drugs Controller General of India (DCGI). These are “Covishield” manufactured by Serum Institute of India (SII) and “Covaxin” manufactured by Bharat Biotech International Limited (BBIL). Several other vaccines are at various stages of clinical development within the country. The National Regulator grants Permission for Restricted Use in Emergency Situations to Sputnik-V vaccine.

Vaccines can prevent infectious diseases. Vaccines do prevent measles, polio, hepatitis B, influenza and many others. When most people in a community are protected by vaccination, the ability of the pathogen to spread is limited. This is called ‘herd’ or ‘indirect’ or ‘population’ immunity. When many people have immunity, this also indirectly protects people who cannot be vaccinated, such as those who have compromised immune systems.

  • A vaccine is basically a training session for the immune system. Vaccines teach the immune system to look for the key features of a virus. So, when a virus does show up, it’s ready to fight it off. 
  • The vaccine gives your body a plan to recognize the virus. Then your immune system starts preparing by making antibodies, or fighter cells, that stay in your blood as protection in case the virus tries to invade. What this means is you get immunity against the disease, without having to get sick first.
  • When enough people’s bodies know how to fight off a virus it has nowhere to go. That slows the spread. When people get a vaccine, we’re able to stop the spread quicker……and get a little closer to ending this pandemic.

Adequate immune response takes 2-3 weeks after completion of entire vaccination schedule i.e., after the second dose of COVISHIELD® and COVAXIN®.

  • Covishield® vaccine, manufactured by the Serum Institute of India, is a Viral Vector based Technology which is also used to manufacture Ebola vaccine.Composition of Covishield includes inactivated adenovirus with segments of Corona Virus, Aluminium Hydroxide Gel, L-Histidine, L-Histidine hydrochloride monohydrate, Magnesium chloride hexahydrate, Polysorbate 80, Ethanol, Sucrose, Sodium chloride, and Disodium edetate dihydrate (EDTA).
  • Covaxin® vaccine, manufactured by the Bharat Biotech, is a whole-Virion Inactivated Corona Virus Vaccine which is also used to manufacture vaccines like Influenza, Rabies and HepatitisA. Composition of Covaxin includes inactivated Corona Virus, Aluminum Hydroxide Gel, TLR 7/8 agonist, 2-Phenoxyethanol and Phosphate Buffered Saline[NKA1].

Which one is better: There is no head-to-head comparison done between the two vaccines being used in India so one cannot choose one over the another. Both would work fine in preventing the infection as well as prevent a person from going into severe state of the disease. As a long-term effect, it would be preventing death for elderly people or those who have co-morbidities.

There are many different COVID-19 vaccines in development using different technologies because it is not yet known which ones will be effective and safe. Based on experience, roughly 7% of vaccines in preclinical studies succeed. Candidates that reach clinical trials have about a 20% chance of succeeding. Different vaccine types may be needed for different population groups. For example, some vaccines may work in older persons and some may not, as the immune system weakens with older age. Several vaccines are needed to allow countries with as much vaccine as possible to increase the supply. Not everyone will be able to be vaccinated right away because of limited supply. It is important that the initial supplies of vaccine are given to people in a fair, ethical, and transparent way.

If the deltoid muscle cannot be used or accessed, the vastus lateralis muscle of the anterolateral thigh can be used.

Yes, you should still be vaccinated because you can become infected more than once. Although you may have some short-term natural protection (known as immunity) after recovering from COVID-19, we don’t know how long this protection will last. Vaccination is the best protection, and it is safe. People who get COVID-19 can have serious illnesses, and some have terrible symptoms that continue for months. If you have had COVID-19, ask your doctor, nurse, or clinic when you should be vaccinated.

Pain is one of the common side effects of the COVID-19 vaccine which should go away in some days. Talk to your doctor about taking over-the-counter medicine, such as ibuprofen, acetaminophen, aspirin, or antihistamines, for any pain and discomfort you may experience after getting vaccinated. You can take these medications to relieve post-vaccination side effects if you have no other medical reasons that prevent you from taking these medications normally. It is not recommended you take these medicines before vaccination for the purpose of trying to prevent side effects.

Antibody testing is not currently recommended to assess for immunity to SARS-CoV-2 following COVID-19 vaccination because the clinical utility of post-vaccination testing has not been established. Antibody tests currently authorized under an EUAexternal icon have variable sensitivity, specificity, as well as positive and negative predictive values, and are not authorized for the assessment of immune response in vaccinated people. Furthermore, the serologic correlates of protection have not been established, and antibody testing does not evaluate the cellular immune response, which may also play a role in vaccine-mediated protection. Finally, antibody testing against nucleocapsid will not detect immune responses resulting from vaccination, but patients may not always know what type of antibody test was used. If antibody testing was performed following vaccination, additional doses of the same or different COVID-19 vaccines are not recommended based on antibody test results at this time. If antibody testing was done after the first dose of an mRNA vaccine, the vaccination series should be completed regardless of the antibody test result.

A COVID Vaccine Certificate (CVC) issued by the government offers an assurance to the beneficiary on the vaccination, type of vaccine used, and the provisional certificate also provides the next vaccination due. It also is an evidence for the citizen to prove to any entities which may require proof of vaccination specially in case of travel. Vaccination not only protects individuals from disease, but also reduces their risk of spreading the virus. Therefore, there could be a requirement in future to produce certificates for certain kinds of social interactions and international travel.

The safety requirements for COVID-19 vaccines are the same as for any other vaccine and will not be lowered in the context of the pandemic. Safety trials begin in the lab, with tests and research on cells and animals first, before moving on to human studies. The principle is to start small and only move to the next stage of testing if there are no safety concerns. Clinical trials are evaluating COVID-19 vaccines in tens of thousands of study participants to generate the scientific data and other information needed to determine safety and effectiveness. These clinical trials are being conducted by manufacturers according to rigorous standards. The COVID-19 vaccines are tested in a broad population of people – not only young, physically fit volunteers, but also older people and people with underlying health conditions. After deployment, the vaccines will continue to be carefully monitored for safety and effectiveness

To ensure that a vaccine is safe, we need to try it on a large number of people. The vaccine developers have not reduced the sample size at any stage of clinical trials rather it was bigger than what we usually test a vaccine on. When a vaccine is tested, most of the adverse events or unwanted effects, if any, occur in the first four to six weeks of its administration. So, in order to ensure that it is safe, we keep a close watch, for the first two-three months, on the people it has been given to. This data help us decide if a vaccine is safe. All concerned in the line of vaccine development, testing and evaluation have followed these procedures to the T. Both Indian vaccines are considered safe on this yardstick. As for the efficacy of the vaccine, we need time to tell how effective a vaccine is. All the global agencies have set the benchmark that only those vaccine candidates which show an efficacy of at least 50-60% will be considered. Most of the vaccines have shown efficacy of 70-90% within the short period of two or three months of observation. Besides when a vaccine is given an emergency use authorizations/permission for restricted use, as in the case of the COVID-19 vaccine, the trial follow-up continues for one-two years to assess the total duration of protection the vaccine will provide.

The body responds to vaccination by making more than one type of antibodies to virus parts including spike protein. Therefore, all vaccines are expected to provide a reasonable amount of protection against the mutated virus also. Based on the available data the mutations as reported are unlikely to make the vaccine ineffective.

Yes. Developing a vaccine generally involves years of research. First, we need a vaccine candidate that is evaluated in animals for its safety and efficacy. After a vaccine candidate passes a preclinical trial, it enters the clinical trial phase. While scientists have worked round the clock in the laboratory, even regulatory approvals which used to take several months have been fast tracked. It helped eliminate all the time lapses between the pre-clinical and clinical trial stages. Earlier, the vaccine development involved a series of steps, but in the case of the coronavirus vaccine, the scientists and regulators worked in tandem, accelerating the whole process without compromises on any protocols and any step.

  • Covishield®: Some mild symptoms may occur like injection site tenderness, injection site pain, headache, fatigue, myalgia, malaise, pyrexia, chills and arthralgia, nausea. Very rare events of demyelinating disorders have been reported following vaccination with this vaccine but without the causal relationship establishment.
  • Covaxin®: Some mild symptoms AEFIs may occur like injection site pain, headache, fatigue, fever, body ache, abdominal pain, nausea and vomiting, dizziness-giddiness, tremor, sweating, cold, cough and injection site swelling. No other vaccine-related serious adverse effects have been reported.

About 10 percent of vaccinated individuals will experience side effects similar to flu-like symptoms, such as fever, chills, headaches, body aches, muscle pain and fatigue. We do not anticipate that these symptoms will last long. If you experience chills, headaches, body aches, muscle pain, joint pain or fatigue within 48 hours after receiving the vaccine, these would likely be post-vaccination symptoms rather than symptoms of COVID-19 infection. Those  who experience any of these symptoms and feel well enough to come to work may return to work. Usually 24 to 48 hours, and no more than a few days. If you experience any respiratory symptoms, such as cough, shortness of breath, new loss of taste or smell, sore throat, vomiting or diarrhea, these are more likely to be COVID-19-related symptoms and very unlikely due to vaccination. You should immediately isolate, and schedule COVID-19 testing.

COVID-19 vaccines are being tested in large clinical trials to assess their safety. However, it does take time, and more people getting vaccinated before we learn about very rare or long-term side effects. That is why safety monitoring will continue. CDC has an independent group of experts that reviews all the safety data as it comes in and provides regular safety updates. If a safety issue is detected, immediate action will take place to determine if the issue is related to the COVID-19 vaccine and determine the best course of action.

People with mild cold-like symptoms are not prevented from getting the vaccine. However, if they are not feeling well, their symptoms just started, or their symptoms are getting worse, they may want to delay vaccination until they feel better; otherwise, they might not be able to tell the effects of illness from those of the vaccine. If they are uncertain, they should speak to their doctor, who has the benefit of their medical history and will be in the best position to help them weigh the potential pros and cons.

Immune issues are of two types:

  • Immunosuppression due to any disease such as AIDS, and people on immunosuppressant drugs such as anti-cancer drugs, steroids, etc.
  • Immunodeficiency in people who suffers from some defect in the body’s protective system such as congenital immunodeficiency.Currently, available COVID-19 vaccines do not have any live virus and therefore individuals with immune issues can have the vaccine safely. But the vaccine may not be as effective in them. One should inform the vaccinator about the medicines they consume and if they are suffering from any known immune issues. The vaccinator should have a record of one’s medical condition.


There are a few bleeding disorders like ‘haemophilia’. These persons should take the vaccine under the supervision of their treating physician. Patients who are admitted in hospital or ICU and have bleeding problems should delay the vaccination till they are discharged. However, several people with heart and brain disorders are on blood thinners like aspirin and antiplatelet drugs. They can continue with their medicines and have the vaccines. For them, vaccines are absolutely safe.

Currently, in India individuals above the age of 18 years will be given COVID-19 vaccine.

There are no medicines or pills proven to prevent coronavirus infection in any person.Only recently, a few vaccines are available, which mainly protect against disease. At present, the vaccines are approved for use in adults only. The best way to protect children is to continue to follow COVID-19 appropriate behaviors:

  • Always maintain a physical distance and stay home as much as possible, unless going for medical treatment or urgent supplies.
  • Wear masks when you are outside, and make sure the face mask is covering your nose. Children above two years of age can also wear a mask.
  • Continually wash hands with soap, or use a 70 per cent sanitizer, making sure the whole surface of the hands is covered.
  • Get vaccinated – everyone above 18 years of age is eligible.
  • Avoid attending public functions, avoid social gatherings, and avoid group play
  • Discuss, demonstrate, and reiterate the importance of COVID-19 Appropriate Behavior (CAB) with your children.

COVID-19 affects all age groups; however, morbidity & mortality is several times higher in adults particularly in those above the age of 50 years. Children have either asymptomatic or mild infection. The general practice is to first evaluate any new vaccine in the older population and then age reduction is done to assess the safety and effectiveness in the paediatric population. The currently available vaccines have not been evaluated in children so far. There are some clinical trials now underway to test the effectiveness and safety of the COVID-19 vaccines in children.

If you are trying to become pregnant now or want to get pregnant in the future, you may get a COVID-19 vaccine when one is available to you. There is currently no evidence that COVID-19 vaccination causes any problems with pregnancy, including the development of the placenta. In addition, there is no evidence that fertility problems are a side effect of any vaccine, including COVID-19 vaccines. Like all vaccines, scientists are studying COVID-19 vaccines carefully for side effects now and will continue to study them for many years.

For most people, it is not recommended to avoid, discontinue, or delay medications for underlying medical conditions around the time of COVID-19 vaccination. However, your healthcare provider should talk to you about what is currently known and not known about the effectiveness of getting a COVID-19 vaccine when taking medications that suppress the immune system. It is not recommended you take over-the-counter medicine – such as ibuprofen, aspirin, or acetaminophen – before vaccination for the purpose of trying to prevent vaccine-related side effects. It is not known how these medications might affect how well the vaccine works. However, if you take these medications regularly for other reasons, you should keep taking them before you get vaccinated. It is also not recommended to take antihistamines before getting a COVID-19 vaccine to try to prevent allergic reactions. If you have questions about medications that you are taking, talk to your doctor or your vaccination provider.

Yes. Women do not need to schedule their COVID-19 vaccine around their menstrual cycle:

  • The immune system is not sufficiently compromised by either the COVID-19 vaccine or the menstrual cycle that scheduling them around one another would be of benefit. Indeed, delaying vaccination around a woman’s cycle may only leave her unprotected from COVID-19 for a longer time without offering any known benefit.
  • The mRNA and adenovirus vaccines are processed in immune system cells near the injection site and then those cells travel through the lymph system to nearby lymph nodes, where additional cells of the immune system are activated. As such, the vaccines would not be expected to affect the menstrual cycle. If a woman experiences a delayed cycle following vaccination, one possible explanation could be hormonal changes caused by stress, which in turn can affect a woman’s cycle. However, women with concerns should speak with their doctor since cycles can be delayed for other reasons as well.
  • The COVID-19 vaccine is not shed after vaccination, so being around recently vaccinated individuals would not be expected to affect someone’s cycle.

Some people are prone to dizziness or fainting (known as vasovagal syncope) that is associated with receiving any kind of injection, or even when a blood sample is taken. Vaccination providers are trained to understand that fainting can occur with any kind of injection. Fainting or syncope usually occurs with other symptoms of anxiety, or in people who have previously had anxiety from a needle-based injection.

No. COVID-19 vaccines do not change or interact with your DNA in any way. Messenger RNA (mRNA) vaccines and a viral vector vaccine. Both mRNA and viral vector COVID-19 vaccines deliver instructions (genetic material) to our cells to start building protection against the virus that causes COVID-19. However, the material never enters the nucleus of the cell, which is where our DNA is kept. This means the genetic material in the vaccines cannot affect or interact with our DNA in any way. All COVID-19 vaccines work with the body’s natural defenses to safely develop immunity to disease.

No, the vaccine does not cause COVID-19. None of the approved COVID-19 vaccines contain the virus that causes COVID-19. It does take a few weeks after vaccination for your body to build up antibodies to protect you from the virus. That means it’s possible you could be infected with the virus that causes COVID-19 just before or just after getting the vaccine and still get sick. If your body develops an immune response to vaccination, which is the goal, you may test positive on some antibody tests. Antibody tests indicate you had a previous infection and that you may have some level of protection against the virus. Experts are currently looking at how COVID-19 vaccination may affect antibody testing results.

While several COVID-19 vaccines appear to have high levels of efficacy, no vaccine is 100% protective. As a result, there may be a small percentage of people who do not develop protection as expected after COVID-19 vaccination.In addition to a vaccine’s specific characteristics, several factors such as a person’s age, their underlying health conditions or previous exposure to COVID-19 may have an impact on a vaccine’s effectiveness. We also do not yet know how long immunity from different COVID-19 vaccines will last. That is one reason why, even as COVID-19 vaccines start to be rolled out, we must continue using all public health measures that work, such as physical distancing, masks, and handwashing.

No, vaccines do not contain live virus. The current technology used that is the mRNA vaccines use a new approach by which mRNA is delivered into our cells to provide the genetic instructions for our own cells to “temporarily” make a “specific” viral protein (the coronavirus spike protein) that triggers an immune response. This mRNA is the main ingredient of the vaccine responsible for causing an immune response.Also known as messenger ribonucleic acid, mRNA is the only active ingredient in the vaccine. The mRNA molecules contain the genetic material that provide instructions for our body on how to make a viral protein that triggers an immune response within our bodies. The immune response is what causes our bodies to make the antibodies needed to protect us from getting infected if exposed to the coronavirus.

None of the vaccines interact with or alter your DNA in any way, and therefore cannot cause cancer.Messenger RNA (mRNA) is not the same as DNA and cannot be combined with DNA to change your genetic code. Here’s now mRNA vaccines actually work: The mRNA vaccines use a tiny piece of the coronavirus’ genetic code to teach your immune system how to make a protein that will trigger an immune response if you get infected. The mRNA is fragile, so after it delivers the instructions to your cells, it breaks down and disappears from the body (in about 72 hours). The mRNA never even goes into the nucleus of the cell — the part that contains your DNA.

Therefore, there is no truth to the myth that somehow the mRNA vaccine could inactivate the genes that suppress tumors.

Rumours or social media posts suggesting that COVID-19 vaccines could cause infertility are not true and totally baseless. Such rumours were floated in the past against other vaccines also e.g. polio and measles. None of the available vaccines affects fertility. All vaccines and their constituents are tested first on animals and later in humans to assess if they have any such side effects. Vaccines are authorized for use only after their safety and efficacy is assured.

No, It typically takes a few weeks for the body to build immunity (protection against the virus that causes COVID-19) after vaccination. That means it’s possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and still get sick. This is because the vaccine has not had enough time to provide protection.

No, it is not true. The vaccine does not affect our immune system adversely. COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. Sometimes this process can cause symptoms, such as fever. These symptoms are normal and are signs that the body is building protection against the virus that causes COVID-19.

Not True. In every vaccine trial, every effect needs to be noted, including all adverse events. The root cause analysis of every side-effect is examined in detail. Pausing a trial and restarting are safety mechanisms to protect the trial volunteers until each adverse effect is investigated and addressed. If the board or the company judges the adverse event to be particularly concerning, they may put the trial on pause — even without yet knowing if the event happened to someone who got the treatment or the placebo. Once a trial is paused, a safety board may ask for a volunteer who experienced an adverse event to be “unblinded”. If the volunteer received a placebo, then the treatment can’t be the cause of the event and the trial can continue.

If it turns out that the volunteer got the treatment, the board does a flurry of detective work. The members look over the medical records. They may ask for more information about volunteers’ health or even order new tests — not just for the people who experienced adverse events, but for everyone in the trial.

At this time, there are no universal requirements for proof of vaccination (e.g. vaccine passport) to travel. If you are traveling by air, each airline has its own unique requirement and recommendations. It is recommended that you check with the airline you are travelling through for their specific requirements. Additionally, certain destinations may have their own vaccine requirements. It’s best to check with the destination to see if there are any travel-related requirements.
Yes, vaccines are for self-protection and the status of being vaccinated does not imply that the person is not carrying or transmitting the disease .However, the health status of the traveller will depend on the antibody status against the virus of COVID 19 at the time of travel.

It is not known how long immunity will last from the COVID-19 vaccine. In the clinical trials that have been conducted to date, the median length of follow-up was two months for vaccine recipients. It is also not known how long immunity from natural infection lasts; there are reports of waning antibody levels around three months after infection, and a few cases of reinfection have been reported. We do know that seasonal coronaviruses (a source for the common cold) do not induce a robust immune response, which leads to limited immunity to these viruses. It is likely that a vaccine will have a stronger and more lasting immune response, but data are limited and the research is ongoing.

Yes, it is absolutely necessary that everyone who has received the COVID vaccine should continue to follow the COVID appropriate behaviour i.e., mask, do gaj ki doori and hand sanitization to protect themselves and those around from spreading the infection.

If you’ve received a COVID-19 vaccine, you’ll need to provide the manufacturer name when you come to donate. In most cases, there is no deferral time for individuals who received a COVID-19 vaccine as long as they are symptom-free and feeling well at the time of donation.

Yes. While experts learn more about the protection that COVID-19 vaccines provide under real-life conditions, it will be important for everyone to continue using all the tools available to us to help stop this pandemic, like wearing a mask over your nose and mouth, washing your hands often, and staying at least 6 feet away from people who don’t live with you. Together, COVID-19 vaccination and following  recommendations for how to protect yourself and others will offer the best protection from getting and spreading COVID-19.
