There can be side effects from the Twinrix vaccine, but they tend to be mild and go away in a few days. Side effects may include:
- redness where you had the needle that may look red on lighter skin or purple on darker skin
- swelling, or feeling sore where you had the needle
- feeling tired or unwell, or getting upset easily
- headache
- fever
- not feeling hungry or not wanting to eat (poor appetite)
- feeling sick to your stomach, vomiting, or loose stool (diarrhea)
At least 1 out of 100 people who got this vaccine reported 1 or more of these side effects. In some cases, it is unknown if the vaccine caused these side effects.
It's important to stay at the clinic for 15 minutes after your vaccine. Some people may have a rare but serious allergic reaction called anaphylaxis. If anaphylaxis happens, you will get medicine to treat the symptoms.
It’s rare to have a serious side effect. Call Health Link at 811 to report any serious or unusual side effects.
