What to Expect With Vaccines

Vaccines are an essential part of staying healthy and preventing disease. They work by introducing a weakened or killed form of a virus or bacteria into the body, which triggers the immune system to produce antibodies that can fight off the disease.

Getting vaccinated

Vaccines are typically given through a shot in the arm or leg, but some can be given through the nose or mouth. The number and timing of doses needed will vary depending on the vaccine and the individual's age and health.

Side effects of vaccines

Vaccines can sometimes cause side effects, but these are usually mild and go away within a few days. Common side effects include:

* Soreness, redness, or swelling at the injection site

* Fever

* Headache

* Fatigue

* Muscle aches

* Nausea or vomiting

Serious side effects of vaccines are rare

In very rare cases, vaccines can cause serious side effects, such as:

* Allergic reactions, which can be life-threatening

* Seizures

* Brain damage

* Guillain-Barré syndrome, a neurological disorder that can cause weakness and paralysis

The benefits of vaccines outweigh the risks

Despite the potential for side effects, vaccines are extremely safe and effective. The benefits of vaccines far outweigh the risks, and they are essential for protecting individuals and communities from disease.

If you have any questions about vaccines, talk to your doctor.
