Will a COVID-19 vaccine prevent me from getting sick with COVID-19?

No vaccine can offer 100% protection, but the vaccines have shown to be incredibly effective in preventing people from getting sick with COVID-19. While breakthrough infections have been reported due to the Delta variant or other reasons, evidence has shown they can significantly reduce the severity of breakthrough illness, and prevent hospitalization and death. 

The more people are vaccinated, and the fewer chances for someone to be exposed to and get COVID-19, the less likely we are to see breakthrough cases. We have seen a small amount of breakthrough cases compared to the millions of people who have been vaccinated.

There is no way to know how COVID-19 will affect you personally. Though many people with COVID-19 only experience a mild illness, others may develop a severe illness, have long-term health effects, or die. Being vaccinated is the most effective way to help end the pandemic and prevent serious, tragic outcomes.
