The Basics: Why Get Vaccinated?

Why should I get vaccinated?

The COVID-19 vaccine is an important and effective tool to keep ourselves and our communities safe.

COVID-19 vaccines offer the best protection against becoming seriously ill, being hospitalized or dying from COVID-19. Even though COVID-19 can be mild, lasting health problems from the disease (known as “Long COVID”) can occur. That's why everyone ages 6 months and older should get vaccinated.

Why should I vaccinate my child?

The COVID-19 vaccine helps keep your family safe and healthy.

Even though COVID-19 is usually milder in children, some children can get very sick or develop lasting health problems. Children can also spread the virus to family members who are at higher risk of getting very sick from COVID-19. The COVID-19 vaccine protects your child getting very sick and helps prevent serious short- and long-term complications of COVID-19. Not only that, vaccinating your child can help keep them in childcare and school, and makes it safer for them to enjoy the activities they love.

The COVID-19 vaccines are safe and effective for adults and children, but it's normal to have more questions. Read our frequently asked questions (FAQs) below to get the information you need to make the decision that is right for you.
