The US Centers for Disease Control and Prevention (CDC) recommends that everyone aged six months and up, including pregnant women, get an annual influenza vaccine. The two fundamental assumptions underlying the CDC’s policy are that vaccination reduces transmission of the virus and reduces the risk of potentially deadly complications. Yet multiple reviews of the scientific literature have concluded that there is no good scientific evidence to support the CDC’s claims.
Notwithstanding the science, to increase demand for the pharmaceutical companies’ influenza vaccine products, the CDC makes use of fear marketing, asserting as fact that tens of thousands of people die each year from the flu, even though the CDC’s numbers actually estimate that are controversial because they are based on dubious assumptions that appear to result in a great overestimation of the negative impact of influenza on societal health.
