Doctors report relying on limited government supplies and using buffer stocks to manage urgent cases.

The Chennai Liver Foundation flagged the issue over a year ago, prompting a government response prioritizing pentavalent vaccines for infants. However, adult formulations continue to be inconsistent.

As per the recommendation of the World Health Organization, all adults should be tested for and vaccinated against Hepatitis B, particularly those at high risk.

Meanwhile, public health officials assure that government stocks are adequate for now and urge the public to seek vaccines at Primary Health Centres, where they remain available free under the UIP.
