COVID-19 Vaccine Information and Resources


Currently authorized vaccines in the United States are highly effective at protecting vaccinated people against symptomatic and severe COVID-19 and a growing body of evidence suggests that fully vaccinated people are less likely to have asymptomatic infection and potentially less likely to transmit SARS-CoV-2 to others. How long vaccine protection lasts and how much vaccines protect against emerging SARS-CoV-2 variants are still under investigation. 

How do vaccines work? 

COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. It typically takes a few weeks after vaccination for the body to build protection (immunity) against the virus. That means it is possible a person could still get COVID-19 just after vaccination, because the vaccine has not had enough time to build immunity.
