What Experts Say

Havrix contains a formalin inactivated strain of Hepatitis A virus grown in human diploid cells. Because the virus is fully inactivated, it cannot cause infection or replicate in the body. The vaccine instead works by exposing the immune system to viral antigens, prompting it to produce protective antibodies.

Doctors across Pakistan recommend this vaccine because of the country's high rate of Hepatitis A exposure through contaminated food and water, especially in crowded urban areas. Children are particularly vulnerable since the infection spreads easily in schools and households. Vaccination lowers both individual risk and community transmission.

The standard schedule uses two doses, with the second given six to twelve months after the first to strengthen and prolong protection. Mild soreness at the injection site, low grade fever and fatigue are commonly monitored after each dose. Anyone with a history of severe allergic reaction to a previous dose should discuss alternatives with their doctor.
