Hepatitis is a viral infection that affects the liver, and in some cases, it can lead to long-term health problems. Fortunately, vaccines are available to protect against two common forms: Hepatitis A and Hepatitis B.
In fact, the hepatitis B vaccine is between 98 percent and 100 percent effective at preventing infection in healthy individuals. Many adults wonder how well these vaccines work and whether they should consider getting them. Let’s understand this in simple terms.
Understanding Hepatitis A and B Vaccines and Their Role in Liver Protection
The hepatitis A vaccine helps prevent hepatitis A, which is usually spread through contaminated food and water. It can cause fever, stomach pain, tiredness and jaundice. While most people recover fully, the illness can still be very unpleasant and may last for weeks.
The hepatitis B vaccine protects against hepatitis B, which spreads through blood and body fluids. It can cause serious liver infections that may become chronic, leading to cirrhosis or even liver cancer. The hepatitis A & B vaccine, often combined in one injection, gives protection against both types at once, making it convenient for those who need full coverage.
How Effective Are Hepatitis A & B Vaccines Over Time?
Research shows that both vaccines are highly effective in adults. The hepatitis A vaccine gives long-term protection after a full course, often lasting for 20 years or more. The hepatitis B vaccine is also very successful, providing immunity in more than 90% of adults who complete the schedule. When given as a combined hepatitis A & B vaccine, the protection is equally strong for both viruses.
The Hepatitis A and B Vaccine Schedule
For Hepatitis A, adults usually need two doses given six months apart to get the best level of immunity. The hepatitis B vaccine is generally given in three doses over a six-month period. The combined hepatitis A and B vaccine schedule may follow a similar timeline, though there are also faster options available for those who need protection quickly, such as travellers. Our pharmacists can help you choose the right schedule for your situation.
Hepatitis A Vaccine Reaction and Safety
Most people have no issues after receiving the vaccine. When reactions do happen, they are usually mild. Common hepatitis A vaccine reaction examples include a sore arm, slight redness, or a mild headache. In some cases, people may feel a little tired or have a low fever for a day or two. These effects are temporary and far less serious than the illnesses the vaccines prevent. Serious reactions are extremely rare, and overall, the vaccines are considered very safe.
Why Adults Should Consider Vaccination
While Hepatitis A and B are often linked with travel, anyone can be at risk. Adults who work in healthcare, plan to visit areas where the diseases are common, or who may be exposed through lifestyle or medical reasons should strongly consider vaccination. Protecting your liver health is vital, and these vaccines provide a reliable and proven way to do so.
