Vaccine What to Know

What is a vaccine?

A vaccine is a preparation used to stimulate the body's immune response against a disease. Vaccines are usually administered through injections, but some can be given orally or through a nasal spray.

How do vaccines work?

Vaccines work by introducing a weakened or killed form of a virus or bacteria into the body. This allows the immune system to produce antibodies against the disease without actually causing illness. When a person is later exposed to the real virus or bacteria, their immune system is able to quickly recognize and destroy it, preventing illness.

Are vaccines safe?

Vaccines are one of the safest medical interventions available. They have been extensively tested and proven to be safe for most people. However, some vaccines can cause side effects, such as pain at the injection site, fever, and fatigue. These side effects are usually mild and go away on their own within a few days.

Who should get vaccinated?

Everyone should get vaccinated according to the recommended schedule. Some vaccines are recommended for all children, while others are recommended for certain adults, such as those who are at high risk for certain diseases.

What are the benefits of vaccination?

Vaccines have saved millions of lives around the world. They have helped to control and eliminate diseases such as smallpox, polio, and measles. Vaccines also protect individuals from developing serious complications from diseases, such as pneumonia and meningitis.

What are the risks of vaccination?

The risks of vaccination are very small. The most common side effects are pain at the injection site, fever, and fatigue. These side effects usually go away on their own within a few days. In rare cases, vaccines can cause more serious side effects, such as allergic reactions. However, these reactions are extremely rare.

Where can I get vaccinated?

Vaccines are available at most doctor's offices, clinics, and pharmacies. You can also find information about vaccines and vaccination schedules online.

Vaccines are an important part of staying healthy. By getting vaccinated, you can protect yourself, your loved ones, and your community from disease.
