Flu jab worked in one in three cases
Posted: 12 Sep 2015, 09:04Last winter's flu jab worked in 34% of cases, according to a final report by Public Health England.
At one stage early in the season, it was estimated that the vaccine was stopping only three out of every 100 immunised people developing symptoms.
But the report said there had been a "shift" in the dominant circulating strains during the rest of the winter.
Prof Paul Cosford, from Public Health England, said its effectiveness had been "slightly lower" than usual.
Flu is a constantly shifting target making it difficult to develop a vaccine. It is why a new jab is needed each year.
Officials are concerned that the drop in the vaccine's effectiveness may affect uptake this coming winter
