COVID-19 Vaccine FAQs

1. How to Book a Vaccination Appointment?

After consulting your doctor, register yourself for getting the vaccination slot, either through the CoWIN App, or the Arogya Setu App. You can discuss with your general practitioner and follow his/her guidance as well for registration.

2. Can You Choose Which of The Approved Vaccines You Want to Take?

Since the coronavirus vaccination drive has begun in India, recipients of the vaccine are not given the choice to select which of the COVID-19 vaccines they want to be inoculated with. You will be vaccinated at the vaccination center with the available vaccine. 

Reports claim that individuals registering themselves during the third phase of the COVID-19 vaccine drive (set to launch on May 1, 2021), will have the option to choose their own vaccination center and pick the one where their choice of jab is being administered. This is subject to change and may vary for different states across the country.

3. Who Should NOT Get Vaccinated?

If you have any symptoms of COVID-19 such as fever, breathlessness, sore throat, cold, cough, body ache, headache, or loss of sense of taste or smell, a day or two before the vaccination appointment or on the day of your appointment, consult your doctor immediately and do not go for the vaccination.

You should not take either Covaxin or Covishield if:

  • You have shown signs of a severe allergic reaction (anaphylaxis) like difficulty in breathing, swelling of the face and throat, fast heartbeat, rashes all over the body, etc., to any previously administered vaccine, drugs, food, or after receiving the first dose of Covaxin or Covishield.

  • You have any bleeding disorders or are on blood thinners (medications that prevent the formation of blood clots).

You can take the Sputnik V vaccine if you have a known history of allergies. It is recommended to get blood tests for Immunoglobulin E and C-reactive protein done in case of allergies. If your results indicate normal limits, there should be no issue getting the shot. 

However, reports suggest that individuals must not take the Sputnik vaccine jab if:

  • You are in an acute stage of an allergic reaction (anaphylaxis)

  • Your body temperature is above 38.5°C (101.3°F)
