Hepatitis A Vaccination
The Hepatitis A vaccine is given via 2 doses in a 6-month period (or more). Immunity builds approximately 2-4 weeks following the initial dose, solidified by the second dose. Once the immunisation programme is complete, protection should last for a minimum of 25 years.
When to get vaccinated
You should plan your vaccine at least 6 months prior to travel as the two injections should be a minimum of 6 months apart.
How it is given
The vaccines are injected into the upper arm in adults.
Children
The vaccine is suitable for children aged one and over.
Risks if you contract Hepatitis A
Symptoms of Hepatitis A can appear 2 to 6 weeks after exposure. Some people, especially younger children, may have mild symptoms or none at all. Common symptoms include tiredness, nausea, vomiting, loss of appetite, mild fever, dark urine, pale stools, and jaundice. Severe cases can lead to acute liver failure, Cholestatic Hepatitis, or death.
Course
Adults have two vaccines, given at least 6 months apart.
Side effects
Short-lived side effects may include a sore injection site, low fever, or tiredness. Severe side effects are rare.
Additional precautions
As well as having the vaccine, it’s vital to practise good food hygiene when cooking and eating, to only drink bottled water, avoid consuming shellfish or raw fruit and vegetables, and avoid unprotected sex.
Before the appointment
Ensure you check the vaccine ingredients for potential allergies and that you are free from high fever on the day of the vaccine.
What is Hepatitis A?
Hepatitis A is a highly contagious liver infection caused by the Hepatitis A virus (HAV). It spreads primarily through the consumption of contaminated food or water, particularly in areas with poor sanitation. Symptoms often include fatigue, nausea, and jaundice, which can last from a few weeks to several months. There is no treatment available other than medication to help with symptoms (source: NHS).
The Hepatitis A virus causes an estimated 200 million infections, 30 million symptomatic infections, and 30,000 deaths each year worldwide (source: National Library Of Medicine).
When travelling to destinations with inadequate sanitation, the risk of contracting Hepatitis A rapidly increases. Travellers should be cautious when consuming street food or untreated water and should seek vaccinations prior to visiting these regions.
The UK is considered a low-risk area for Hepatitis A. The country benefits from excellent sanitation standards, food safety regulations, and community-wide immunisation.
