Side Effects of the COVID-19 Vaccine
The COVID-19 vaccine helps your body learn how to defend itself from the disease. You may feel uncomfortable for two or three days after you receive the vaccine. After being vaccinated, you may feel some side effects such as:
- Muscle pain
- Soreness in your arm
- Body aches
- Feeling tired
Side effects are a sign that your body is building up protection from COVID-19. They may be uncomfortable, but they are much less harmful than having COVID-19.
