Could Headache Most Of The Day Be Side Effects I Got My 2nd COVID Vaccine?

Posted on Wed, 19 Feb 2025

Question: I am 65 years old and got my 2nd COVID vaccine last Friday (February 19). My husband did as well. It went well with no side effects. Today exactly one week later, I have had a headache most of the day, felt achy and chilled and extremely tired. My husband felt the exact same way yesterday but is fine today. Could this be side effects just showing up?

Brief Answer:
Probably side effects of the COVID vaccine.

Detailed Answer:
Hello ,

Your symptoms seem to be related to side effects of the COVID vaccine.
These side effects are completely normal.
You should not be worried.
You may take an anti inflammatory medication such as Acetaminophen to relieve the symptoms.
I also recommend to rest and drink liquids.
These side effects will probably go away on its own.

Hope I have answered your query. Let me know if I can assist you further.

Kind regards!

Do you have any idea why it would take a week for these side effects to show up on us? I thought they occurred within 24-48 hours after receiving the vaccine.

Brief Answer:
The side effects may start a few days after the vaccine

Detailed Answer:
Hi again dear,

The side effects of the vaccine may start a few days after the vaccine and may last up to two weeks.
So, the side effects in your case are completely normal.

How it helps dear,
