Expecting some side effects post-vaccination is normal. The usual side-effects people report right now are mild, reactogenic ones, including pain at the injection site, fever, rashes, fatigue, body pain, headache and malaise.
Adverse reactions, including the rare complications of blood clotting which has been associated with the Oxford-Astrazeneca and Johnson and Johnson vaccine, has so far not been observed in India.
All vaccines approved for use are safe for use and carry good tolerability and effectiveness. Therefore, every individual eligible for inoculation should sign up to get their jabs as and when they can.
Remember, not only do vaccines cut down severity and mortality risk with COVID, getting temporary side-effects from the vaccine is better than contracting COVID right now.
