Flu Vaccine Effectiveness Report

Flu Vaccine Effectiveness Report

The Center for Disease Control and Prevention conducts studies each year to estimate how well the flu vaccine protects people from getting sick against the Influenza virus.  This is called vaccine effectiveness (VE) and is largely based on the information that the CDC is able to collect during the flu season.

According to the CDC, effectiveness against flu A (H3N2) virus (the main virus spreading this season) is estimated to be 47%, while effectiveness against flu B was 67% for all ages. “This indicates that vaccination with the 2012-2013 flu season vaccine reduced the risk of flu-associated medical visits from flu A (H3N2) viruses by one half and from flu B viruses by two-thirds for most of the population.” However, the CDC notes that the exception to the results was the effectiveness of the flu vaccine against flu A (H3N2) viruses among people aged 65 years and older which was lower at 9%.

Overall, the CDC says that vaccine effectiveness estimates are within the range expected during flu seasons.

Worst Flu Season in 10 Years in the US

Worst Flu Season in 10 Years in the US

Many hospitals in the US are struggling to manage the influx of patients with the flu.  The Center for Disease Control and Prevention (CDC), the US federal agency in charge of protecting public health and safety, believes that the number of influenza cases reported is nearing epidemic levels in the US as of January 2013, the worst in 10 years.  Though the CDC has still not declared an epidemic, concern is raised across 41 states for the 2012-2013 Influenza Season (November to March) where over 2,000 people have already been hospitalized as of October 2012.
