COVID-19 vaccination can help keep you from getting COVID-19. COVID-19 vaccines are being carefully evaluated in clinical trials and will be authorized or approved only if they are shown to be safe and effective in reducing your chances of getting COVID-19. Based on what we know about vaccines for other diseases, experts believe that getting a COVID-19 vaccine may help keep you from getting seriously ill even if you do get COVID-19. Getting vaccinated yourself may also protect people around you, particularly people at increased risk for severe illness from COVID-19.
COVID-19 vaccination will be an important tool to help stop the COVID-19 pandemic. Wearing masks and social distancing help reduce your chance of being exposed to the virus or spreading it to others, but these measures are difficult to maintain for long periods of time. Vaccines will work with your immune system so it will be ready to fight the virus if you are exposed.
