You can still get infected with Covid-19 after being vaccinated. This is not because the vaccine gave you the virus. Vaccines don't contain the virus itself — just the sequence. Here’s why:
▪️ Immunity doesn't kick in right away: It takes time for vaccines to build up immunity. People can be exposed to coronavirus right before or after being vaccinated, and there won't be time for the body to develop its defenses.
▪️ Vaccines might not provide perfect protection: Both vaccines provided about 95% protection in clinical trials, which means 5% of people might still catch the virus even after two shots.
▪️ Immunity may wane over time: No one knows how long the vaccines out now will protect people from infection. There is also the possibility that Covid-19 might mutate in a way that makes the vaccines less effective.
