Side effects have been reported with both the Pfizer-BioNTech Covid-19 Vaccine and the Moderna Covid-19 Vaccine. These include:
- Injection site pain.
- Muscle pain.
- Joint pain.
- Injection site swelling.
- Injection site redness.
- Feeling unwell.
- Swollen lymph nodes (lymphadenopathy).
There is a remote chance that the vaccine could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to one hour after getting a dose of the vaccine. For this reason, your vaccination provider may ask you to stay at the place where you received your vaccine for monitoring after vaccination. Signs of a severe allergic reaction can include:
- Difficulty breathing.
- Swelling of your face and throat.
- A fast heartbeat.
- A bad rash all over your body.
- Dizziness and weakness.
