Possible Side Effects After Getting a COVID-19 Vaccine
Watch out for these symptoms: Some side effects of the vaccine may be similar to COVID-19. COVID-19 is not caused by the vaccine.
Side effects of the vaccine do not include a sore throat or runny nose. If you have any symptoms of COVID-19, you should stay at home until you feel better. You can also seek medical attention if your symptoms worsen.
* Call 8-1-1 if you have any concerns. The vaccine is rarely associated with serious side effects.
You should seek immediate medical attention if you experience any severe side effects or an allergic reaction, such as hives, swelling, or difficulty breathing. Inform them that you have received the COVID-19 vaccination
COVID-19 vaccination protects people from contracting it. Side effects are normal signs that the body is building immunity. Side effects can affect people’s ability to perform daily activities but should disappear within a few days. Some people may experience no side effects. Allergic reactions are uncommon.
Any vaccination, COVID-19 included, is not likely to cause long-term health problems. Adverse effects usually occur within six weeks after receiving a dose of the vaccine. The U.S. Food and Drug Administration (FDA), collected data for each COVID-19 vaccine during clinical trials. This was to ensure that the data remained current for at least two months (eight weeks) after the last dose. Even though the vaccines have been approved, the FDA, CDC, and other federal agencies continue to monitor the safety of COVID-19 vaccinations.
Common Side Effects
On the arm where you got the shot:
Throughout the rest of your body:
- Muscle pain
Here are some helpful tips to help you get rid of side effects
Talk to your doctor about over-the-counter medication, such as acetaminophen or aspirin (only for those 18 and older), or antihistamines, for any pain or discomfort you feel after being vaccinated.
These medications can be used to treat the side effects of vaccinations if there are no medical reasons. Talk to your healthcare provider about non-aspirin pain relief and other ways you can comfort your child after vaccinations.
These medicines should not be taken before vaccination to avoid side effects.
To reduce pain and discomfort where the shot is given
- Apply a clean, cool, wet washcloth over the area.
- Use or exercise your arm.
To reduce discomfort from fever
- Drink plenty of fluids.
- Dress lightly.
After a second shot or booster shot
Side effects from the second shot can be more severe than those experienced after the first shot. These side effects are normal and should resolve within a few days.
The reactions to the booster shot have been similar to those following either the single-dose or two-dose primary shots. Side effects that were most frequently reported were fever, fatigue, pain at the injection site, and headaches. However, the majority of side effects were mild or moderate. Severe side effects can still occur, but they are uncommon, just like with single-dose or two-dose primary shots.
When should you call the doctor?
Side effects can impact your ability to perform daily activities and may affect you or the child. However, they should disappear within a few days.
- After 24 hours, the tenderness or reddening of the area where the shot was administered becomes more severe
- Side effects that persist or become more severe after a few days are considered serious.
You or your child have received a COVID-19 vaccination and are concerned that they may be experiencing severe allergic reactions after visiting the vaccination site. Call 911 immediately to get immediate medical attention. Learn more about CoVID-19 vaccines and rare severe allergic reactions.
If you have no side effects
The reactions to the COVID-19 vaccine may vary from one person to another. The majority of people who participated in clinical trials had only mild side effects. Some even experienced no side effects. These people had strong immunological responses to vaccines. You are protected from severe COVID-19 infection by vaccination, regardless of side effects.
