Flu vaccine may only be 10 percent effective, experts warn

Health officials warn of bad flu season this year, but still recommend the flu shot.

Fleming said four might not seem like a lot but confirmed cases "are the tip of the iceberg".

Two Flathead County residents have died from the flu, marking the states first influenza-related deaths this season, the Flathead City-County Health Department reported Wednesday. Experts believe that the U.S. will have to endure the most risky flu season, with the same characteristics as the 2014 outbreak. This after the vaccine wouldn't work on several strains of flu in South America.

Previous year in Canada and the USA, the vaccine was found to be only 35 per cent effective in preventing cases of H3N2 influenza, she said.

The H3N2 flu strain is going to hit America and so far it has been responsible for the biggest outbreak over the last years.

'Some of the early assessments of the vaccine from the Australia epidemic in their winter, our summer, suggest about a 10 percent vaccine efficacy which would then mean it was 10 percent effective in preventing the disease'.

There are also concerns that this year's flu shot may not be all that effective in preventing the respiratory illness.

This possibility underscores the need to strive toward a "universal" influenza vaccine that will protect against seasonal influenza drift variants as well as potential pandemic strains, with better durability than current annual vaccines.

The findings come from the Australian Government Department of Health, and more importantly for Central Texans, the flu shots used in the Australian study are made of the same components as the flu shots administered right here in Waco.

While in the past years the flu season started in February, this year the number of people hospitalized due to suffering influenza symptoms has increased. Anybody who develops the flu can pass it along to someone at high risk of severe illness, including the elderly and infants younger than 6 months old who are too young to get the vaccine.

According to the study, a strain of the H3N2 virus with a different outer layer protein emerged during the 2014-2015 flu season. Nationwide since October 1, 566 have been hospitalized for influenza and 148 million doses of the flu vaccine have been distributed. Between the same time period a year ago, there were 2,510.

In B.C., for instance, low levels of H3N2 infection have been confirmed since the beginning of the season in late August, but a strain known as B/Yamagata has also been found circulating within the population.
