CDC offers advice on what to expect after getting a COVID-19 vaccine
The COVID-19 vaccination will help protect you from getting the novel coronavirus. But after getting the shots, you may experience some side effects, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days.
Common Side Effects
On the arm where you got the shot, you may experience:
• Pain
• Swelling Throughout the rest of your body, you may have:
• Fever
• Chills
• Tiredness
• Headache Helpful Tips
If you have pain or discomfort, talk to your doctor about taking over-the-counter medicine, such as ibuprofen, aspirin, antihistamines or acetaminophen, for any pain and discomfort you may experience after getting vaccinated. You can take these medications to relieve post-vaccination side effects if you have no other medical reasons preventing you from taking them normally. It is not recommended you take these medicines before vaccination in an attempt to prevent side effects because it’s not known how they may impact the effectiveness of the vaccine.
To reduce pain and discomfort where you got the shot:
• 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.
When to Call the Doctor
In most cases, discomfort from fever or pain is normal. Contact your doctor or healthcare provider:
• If the redness or tenderness where you got the shot increases after 24 hours.
• If your side effects are worrying you or do not seem to be going away after a few days.
If you think you might be having a severe allergic reaction, seek immediate medical care by calling 911.
Remember: Side effects can affect your ability to do daily activities, but they should go away in a few days.
With most COVID-19 vaccines, you will need two doses in order for them to work. Get the second shot even if you have side effects after the first shot, unless a vaccination provider or your doctor advises against it.
It takes time for your body to build protection after any vaccination. COVID-19 vaccines that require two shots may not protect you until a week or two after your second shot. It’s important for everyone to continue using all the tools available to help stop this pandemic as we learn more about how COVID-19 vaccines work in real-world conditions. Cover your mouth and nose with a mask when around others, stay at least 6 feet away from others, avoid crowds, avoid poorly ventilated spaces, and wash your hands often.
