Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus (HAV). The virus can spread through contaminated food, water, or close contact with an infected person. Hepatitis A immunisation is a safe and effective way to protect against the infection. However, like all vaccines, it can cause side effects. In this article, we will discuss the common and rare side effects of the hepatitis A immunisation, as well as what you need to know before getting vaccinated.
What is Hepatitis A Immunisation?
The hepatitis A immunisation is a vaccine that stimulates the body’s immune system to produce antibodies against the hepatitis A virus. The vaccine is usually given as a single dose, but a booster dose may be required after 6-12 months for certain individuals, such as those with weakened immune systems or who are at high risk of exposure.
Common Side Effects of Hepatitis A Immunisation
Like all vaccines, the hepatitis A immunisation can cause side effects, but most of them are mild and temporary. The common side effects of the hepatitis A immunisation include:
- Pain, redness, or swelling at the injection site (about 1 in 5 people)
- Fatigue or feeling tired (about 1 in 10 people)
- Headache (about 1 in 10 people)
- Loss of appetite (about 1 in 10 people)
- Nausea or vomiting (about 1 in 10 people)
These side effects usually resolve on their own within a few days. If the side effects persist or worsen, it is essential to consult a healthcare professional.
Rare but Serious Side Effects of Hepatitis A Immunisation
While rare, the hepatitis A immunisation can cause serious side effects, including:
Allergic Reactions
Some people may be allergic to the hepatitis A vaccine, which can cause an allergic reaction. Symptoms of an allergic reaction include:
- Hives or itchy skin
- Swelling of the face, lips, or tongue
- Trouble breathing or swallowing
- Rapid heartbeat
- Dizziness or fainting
If you experience any of these symptoms, seek medical attention immediately.
Guillain-Barré Syndrome (GBS)
GBS is a rare autoimmune disorder that can occur after vaccination, including the hepatitis A vaccine. Symptoms of GBS include:
- Muscle weakness or tingling sensations in the legs or arms
- Loss of muscle control or paralysis
- Trouble with eye and facial movements
- Difficulty with bladder control or bowel function
If you experience any of these symptoms, seek medical attention immediately.
| Side Effect | Frequency |
|---|---|
| Pain, redness, or swelling at the injection site | About 1 in 5 people |
| Fatigue or feeling tired | About 1 in 10 people |
| Headache | About 1 in 10 people |
| Allergic reactions | Rare (less than 1 in 100,000 people) |
| Guillain-Barré Syndrome (GBS) | Extremely rare (less than 1 in 1 million people) |
