COVID-19 Vaccines: What You Need to Know

An educational video series to help you better understand the vaccines and how they help stop the spread of COVID-19.

For two years, we have all made big and small changes in our daily lives to stay healthy and safe. From daily self-screening of symptoms, to limiting our contact with others, to wearing masks and physically distancing, to increased hand washing.

Now, we can finally get control of COVID-19. Vaccines help us to stop the spread. With every vaccination, our families and communities are one step closer toward a healthier future.

Understanding how vaccines work is an essential step in understanding why vaccination is so important. Below is a video series to help you understand the science behind vaccinations, with an even deeper dive into COVID-19 vaccines. You’ll learn the facts about how the human body fights infectious diseases, details on COVID-19 vaccine efficacy and safety, and what you can expect when you get vaccinated.
