Both covaxin and covishield are fine but if we talk about efficacy recent studies suggest covaxin efficacy is 81% wherever covishield efficacy is 72%
The gap between the two doses of covaxin is 4 weeks whereas of covishield is 6-8 weeks
But the latest and best till now is the vaccine sputnik whose efficacy is near about 90% and the gap between 2 doses are 3 weeks
Health Tips
there are no very significant differences between the vaccines available in India...seeing the crisis just get whichever is available...but definitely get your shot asap
