The vaccine is recommended as the first booster shot and will be administered twice with a gap of 28 days to adults over 18 who have completed two doses of Covaxin or Covishield but have not taken the booster shot. Side effects are generally mild and may include headache, fever or runny nose. It is not recommended for individuals who are allergic to any of its components or have had severe allergic reactions in the past. The vaccine is available at hospitals and will be circulated among people from the fourth week of January. You can book your appointment early.
