A study released today by the Center for Disease Control and Prevention (CDC) shows shockingly low rates of effectiveness for this year’s flu vaccine.
According to the report, the flu vaccine was effective for only 9% of seniors over 65 years old. In other words, 91% of seniors who were vaccinated in the study still ended up getting the flu.
The CDC showed somewhat better results for younger persons. They claimed that the flu vaccine was effective for 58% of those aged 6 months-17 years, 46% for persons aged 18–49 years, and 50% for persons aged 50–64 years.
Overall, the CDC claimed this year’s flu vaccine was “moderately effective” and made the unprovable claim that “influenza vaccination reduced the risk for medical visits resulting from influenza A and B by 56%.”
But since young people generally have stronger immune systems than seniors it’s unclear how many of the younger test subjects would not have gotten the flu whether they were vaccinated or not.
