Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus (HAV). The Hep A jab, also known as the hepatitis A vaccine, is a safe and effective way to protect against this infection. While the vaccine is generally well-tolerated, it's essential to be aware of the potential side effects. In this article, we'll explore the common and rare side effects of the Hep A jab, as well as what you need to know before getting vaccinated.
Common Side Effects of the Hep A Jab
The Hep A jab is made from inactivated hepatitis A virus, which means it can't cause the infection itself. However, like all vaccines, it's not entirely side-effect-free. The most common side effects of the Hep A jab are mild and temporary, including:
- Pain, redness, or swelling at the injection site (up to 50% of people)
- Fatigue (up to 20% of people)
- Headache (up to 15% of people)
- Nausea or vomiting (up to 10% of people)
- Loss of appetite (up to 5% of people)
These side effects usually resolve on their own within a few days. It's essential to note that the risk of serious side effects from the Hep A jab is extremely low.
Rare but Serious Side Effects
While rare, some people may experience more severe side effects from the Hep A jab. These include:
| Side Effect | Frequency |
|---|---|
| Allergic reactions (such as hives, itching, or difficulty breathing) | Less than 1 in 100,000 |
| Guillain-Barré Syndrome (a rare nerve disorder) | Less than 1 in 1 million |
| Thrombocytopenia (low platelet count) | Less than 1 in 100,000 |
If you experience any severe side effects, seek medical attention immediately.
