Hep A and B Vaccination

Did you know that more than 257 million people globally are living with hepatitis B, and around 1.4 million people are infected with hepatitis A each year? These staggering numbers highlight the widespread prevalence and significant health risks associated with these infections.

I. What are Hepatitis A and B?

Hepatitis A and B are viral infections that affect the liver. Hepatitis A is primarily transmitted through contaminated food and water, while hepatitis B spreads through contact with infected bodily fluids such as blood, semen, and vaginal fluids. Both viruses can lead to severe liver damage, cirrhosis, and even liver cancer if left untreated.

II. Importance of Vaccination:

• Preventing Serious Illness: 

Vaccination is the most effective way to prevent hepatitis A and B infections and their associated health complications. Vaccines have been proven to significantly reduce the incidence of these diseases, protecting individuals and communities.

• Long-Term Protection:

The hepatitis A and B vaccines provide long-lasting immunity. In most cases, individuals who complete the vaccination series are protected for life, making vaccination a crucial step in safeguarding your health.

III. The Vaccines:

• Hepatitis A Vaccine: 

There are two types of hepatitis A vaccines available: the inactivated (killed) vaccine and the live attenuated (weakened) vaccine. The inactivated vaccine is more commonly used and is administered in two doses, six months apart, providing long-term protection against hepatitis A.

• Hepatitis B Vaccine: 

The hepatitis B vaccine is administered in three or four doses over six months. The typical schedule involves an initial dose, followed by additional doses at one month and six months. This series ensures robust and long-lasting immunity against hepatitis B.

• Combined Vaccine: 

For convenience, a combined vaccine that protects against both hepatitis A and B is available. This vaccine is administered in three doses over six months, offering comprehensive protection with a simplified schedule.

IV. Who Should Get Vaccinated?

• High-Risk Groups: 

Certain groups are at higher risk of contracting hepatitis A or B and should prioritise vaccination. These include:

• • Travellers: Especially those visiting regions with high rates of hepatitis A or B.
  • Healthcare Workers: Due to potential exposure to infected blood and bodily fluids.
  • People with Chronic Liver Disease: They are more susceptible to severe complications from hepatitis infections.
  • Individuals with High-Risk Behaviours, Such as those with multiple sexual partners or intravenous drug users.
  • Infants Born to Infected Mothers: They are at high risk of mother-to-child transmission of hepatitis B.

• Routine Vaccination: 

Routine vaccination is recommended for all infants, children, and adults, depending on their age and risk factors. Ensuring routine vaccination helps protect the broader population and reduces the spread of these infections.

• Consultation with Doctor: 

It’s essential to consult with your doctor to assess your risk and determine if hepatitis A and B vaccinations are recommended for you. Your doctor can provide personalised advice based on your health status and lifestyle.

V. Safety and Side Effects:

• Vaccine Safety: 

The hepatitis A and B vaccines have a strong safety record and are approved by health authorities worldwide, including the Health Sciences Authority (HSA) in Singapore. They have been extensively tested and monitored for safety and efficacy.

• Potential Side Effects: 

Common and mild side effects of the vaccines may include:
