More young parents have become reluctant to have their children vaccinated against hepatitis B as infant deaths after the inoculation have increased.

But medical experts are continuing to urge parents to stick with the program, saying that blaming the vaccine for all infant deaths isn't responsible and warning of an outbreak of the disease among children if they don't get the shots.

Meanwhile, doctors ruled out the vaccine as the cause of the death of a 1-month-old infant in Hubei province, local authorities said on Wednesday.
