What Experts Say

Havrix contains an inactivated form of the hepatitis A virus, which cannot cause infection but trains the immune system to recognize and fight the real virus.

It is given as two doses in the upper arm muscle, the first dose followed by a booster 6 to 12 months later for long term protection.

Hepatitis A spreads through contaminated food and water, which makes vaccination especially useful in areas of Pakistan with inconsistent clean water access. Mild soreness at the injection site is common and expected.
