Flu Shot Less Effective This Season

As you‘ve probably heard, the flu shot is drastically less effective this year because the current strain of the virus has mutated. During an average winter when the flu vaccine has been considerably more effective than this year’s vaccination, the number of reported hospitalizations and deaths is still common. So, imagine the concern when doctors and medical professionals are faced with knowing that the vaccination administered to ward off the flu is ineffective.

In February 2014, a panel of experts decided on 3 strains of the virus to include in this year’s vaccine, based on data about the common strains circulating around the globe throughout the year. Some years the vaccine is a better match to the circulating strains than others.

The most common strain of the virus reported so far this season is influenza A (H3N2). In the past, this strain has been linked to higher rates of hospitalization and death, especially for those at high risk for complications, which is usually the very young, the elderly and those with chronic health conditions such as asthma or heart problems.

While this year’s version is not as protective against a mutated strain, it can still decrease the severity of illness caused by the virus. The most effective way to prevent the disease and/or severe outcomes from the illness is vaccination – even in its diminished capacity. For a complete list of Influenza Testing Kits, visit our site.
