Hepatitis A and B are serious liver infections that can cause significant health complications. Vaccination is the most effective way to prevent these infections and protect your health. In Singapore, the Ministry of Health (MOH) recommends that all individuals get vaccinated against hepatitis A and B.
Understanding Hepatitis A and B

Importance of Vaccination
According to the World Health Organization (WHO), hepatitis A and B are major public health concerns worldwide. In Singapore, the prevalence of hepatitis B is estimated to be around 0.5%, while hepatitis A is less common.
Vaccination is the most effective way to prevent hepatitis A and B. Vaccines are highly safe and effective, and they provide long-term protection against these infections.
