Babies have been getting the hepatitis B vaccine worldwide since 1991, the US panel’s decision to scrap the recommendation has caused controversy, with health experts saying it “puts infants at unnecessary risk.”
Vaccine makers expressed concern on Friday’s decision (Dec 5) by a US advisory panel to scrap its long-standing recommendation that all infants receive a hepatitis B vaccine at birth, a shift that public health experts fear will undermine decades of public health advances.
Merck, whose Recombivax HB has been a staple of the US childhood immunisation programme, said it was “deeply concerned” by the decision of the CDC’s Advisory Committee on Immunisation Practices (ACIP), warning it “puts infants at unnecessary risk of chronic infection, liver cancer and even death.”
The company said the universal birth dose, which was instituted in 1991, has driven a 99 per cent drop in acute hepatitis B cases in children and young adults and argued there is no evidence that delaying it provides any benefit. Infectious disease experts, as well as organisations representing paediatricians, pharmacists and public health professionals decried the move.
Hepatitis B, which can spread from mother to child during birth, can cause severe liver disease and early death, and has no cure. According to the National Foundation for Infectious Diseases, the universal hepatitis B birth dose has prevented more than 500,000 childhood infections, cut infant cases by 95 per cent and averted an estimated 90,100 deaths.
Many of the committee members, which were appointed by US Health and Human Services Secretary Robert F. Kennedy Jr., a long-time vaccine sceptic, criticised the vaccine safety data and said that the US vaccine schedule was out of step with other countries, particularly Denmark, that have low hepatitis B rates.
GSK said it stands behind the science supporting its vaccine and is awaiting the CDC’s formal adoption of the recommendation to assess its impact.
Its vaccine, Engerix-B, has been approved since 1989, with 1.4 billion doses administered worldwide.
Merck and GSK shares fell about 1 per cent each following the vote. US-listed shares of Sanofi, another maker of hepatitis B shots, rose about 0.7 per cent.
