@emma jessica,
Quote:But nowadays vaccines are being injected into people as a cure for corona.
It's not a cure or a treatment for people who have contracted the virus.
Quote:Some of them are well now.
That's not due to the vaccine.
Quote:But one can see its rise again. What could be the reason behind it?
As the virus spreads it mutates and some of these variants are believed to be more contagious and more serious. Also, many people stopped following social distancing and mask protocols because the temporary drop in the rate of infection gave them a false sense of security.
