COVID-19 vaccines are effective in preventing you from getting COVID-19, but they have other benefits as well. In the rare event that you do get COVID-19 anyway, the vaccine can help keep you from getting seriously ill. Being vaccinated can also protect the people around you, particularly people who are at increased risk of becoming seriously ill from COVID-19. Vaccination against COVID-19 is a safer way to help build immunity. COVID-19 can have serious and life-threatening complications, and there is no way to know how getting COVID-19 will affect you.
COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. It usually takes a few weeks after vaccination for the body to develop protection (immunity) against the virus. That means a person may still get COVID-19 right after vaccination because the vaccine hasn’t had enough time to build immunity.
You may have some side effects after getting vaccinated.
