Child swine flu vaccine results positive

Researchers in the U.K. say that a trial of swine flu vaccines has shown to provide “good protection” against the virus, according to the results of a Health Production Agency study released by the BBC.

Approximately 900 children between the ages six months and nine years old were volunteered for the study, which was conducted by the Health Protection Agency in conjunction with Universities of Bristol, Oxford, Southampton, Exeter and St George's in London.

The trial compared two types of swine flu vaccines – the adjuvanted vaccine, or split virus vaccine and the “whole virus” vaccine, according to the BBC.

The adjuvanted vaccine was the most commonly used on children during the pandemic, the report stated. However, it was also the most likely to cause side effects such as fever.

According to the researchers, 98 percent of children under three years of age responded well to two doses of the “adjuvanted” vaccine. Approximately 80 percent of the children from the same age group responded to two doses of the “whole virus” vaccine.

Researchers reported that the difference between the vaccines in children over the age was markedly less pronounced. Approximately 99 percent from that age group responded well to the adjuvanted version and 95 percent responded well to the whole virus vaccine.

"Most children receiving either vaccine had no more than minor reactions, and this study provides reassuring evidence that both vaccines were well tolerated and likely to provide good protection against swine flu,” Dr. Matthew Snape, of the  Oxford Vaccine Group at The University of Oxford, said. “Traditionally the under threes don't tend to respond well to flu vaccines. This could show us the way to improve seasonal flu vaccines and help make a vaccine that generates a better response in young children.”
