Flu vaccine may not reduce hospital admission in children

  • Comment
The flu inoculation may not reduce hospital admissions or physician visits in young children, as the vaccine may not match circulating strains of the virus, according to a study.

Researchers in New York studied 414 children under 5 who developed influenza during the winters of 2003-4 or 2004-5 and their vaccination status was compared with over 5000 children who did not catch the flu.

Significant flu vaccine effectiveness was not evident in either of the seasons studied – there was an estimated range of effectiveness from 7-52% in fully vaccinated 6-59 month olds.

The study noted that the strains of the virus used in vaccines were not suitable. For example, in 2003-4 the influenza A virus was responsible for 99% of circulating strains and only 11% of vaccines contained the correct virus.

Authors wrote: ‘Further studies of influenza vaccine effectiveness are needed using a variety of study designs to assess the yearly impact of influenza vaccination programmes for children.
