mass vaccination program of hepatitis B vaccination for infants should be reevaluated. Feared that the vaccine failed to establish the pattern of antibodies in children so that it remains vulnerable to the virus.

Professor of Microbiology, University of Airlangga Lusida Maria Inge said, the failure of antibody development was recorded in research in one district in East Java last year.

In a joint research team of the University of Kobe, Japan was known to only 23.6 percent of children had antibodies to hepatitis B. “There are 80 percent of children have received hepatitis B vaccination,”

Thus, there are 76.7 percent of children in the district vulnerable to suffering from hepatitis B. In the long run, the virus can cause liver cancer or cirrhosis of the liver.

“We found there was a pause time of birth and vaccination. Some kids just got a vaccine after the age of two months,” he said.

In fact, there is no certainty of a baby infected with hepatitis B virus from mother or not. If infected, there is a time of month for the virus to adapt to the child’s body. Vaccination after the age of two months instead trigger the feared mutation of the virus.

“I proposed a re-evaluation of hepatitis B vaccination program has been underway since 1997,” he said.
