20% Effective Flu Vaccine saves tens of thousands of people
(AP)-A new study sheds light on the benefit of doing so. Even when the flu shot is just 20% effective it can still reduce US doctor visits due to illness by an estimated 20 million in a single year, the new report published in the scientific journal PNAS (Proceedings of the National Academy of Sciences of the United States) finds.
In addition, vaccination also can prevent thousands of hospitalizations and deaths, the study authors estimated based on the average vaccination coverage rate in the United States.
In fact, the Centers for Disease Control and Prevention estimated just 36% effectiveness for the 2017-18 seasonal vaccine as of February 3.
The season ends this month.
The research team found that at the average rate of US coverage even a poor vaccine would prevent a significant amount of illnesses, hospitalizations and deaths.
