Children’s vaccine 87% effective against prevailing flu strain

Public Health England (PHE) has published mid-season data on the effectiveness of this year’s flu vaccines.

The data suggests that the nasal spray flu vaccine is 87% effective in children aged 2 to 17 years against the main circulating strain, influenza A(H1N1)pmd09.

The vaccine given to adults aged 18 to 64 in at-risk groups is estimated to be 39% effective against the same strain. Influenza A(H1N1)pdm09 has been the main strain circulating this season. As the number of cases is lower, a precise estimate for those aged 65 and over will not be available until the end of the season.
