MA Department of Public Health 2025-2026 COVID-19 Vaccine Recommendations

Staying up to date on immunizations by getting vaccines at the recommended time is the best way to protect against serious diseases. Vaccines train the body to fight against disease causing germs before actually getting sick. Vaccines don't only protect you, but they protect those around you. Using vaccination to develop protection from diseases allows people to live healthy lives without the fear of long-term side effects from preventable illnesses.

Vaccine Frequently Asked Questions

How do vaccines work to protect us?

Vaccines are either made of very small amounts of germs that won't make you sick, or information that your body will use in an immune response. The small amount of germs in the vaccine trigger something called an immune response. An immune response trains your body to recognize disease causing germs and teaches your cells how to fight them off if they ever do invade your body.

How do we know that vaccines are safe?

Vaccines are thoroughly researched and tested to understand their ability to protect your body and keep you safe. The Food and Drug Administration (FDA) has a long review process for vaccines to go through before they are given out to the public. Even after they are given out for public use, the FDA continues to monitor the outcomes of vaccines and ensure they remain safe for use.

Do vaccines have side effects?

Some vaccines do have side effects. The most common side effects are a sore arm due to the injection or a low-grade fever. Most side effects resolve within 3 to 5 days. There is a very small risk that serious effects could occur if there is an allergic reaction to a part of the vaccine. Make sure to double check with your provider before getting a vaccine.
