From Dr. Mercola:
Despite the fact that last year’s (2014 to 2015) flu vaccine was a major flop with an abysmal 18 percent effectiveness rate, the US Centers for Disease Control and Prevention (CDC) publicly expressed unreserved confidence in this year’s (2015-2016) vaccine.
In September 2015, CDC Director Tom Frieden said in a news conference, “Get vaccinated That’s the best way to protect yourself, your family and your community against flu.”1
That was in August 2015 and the “get vaccinated” advertisements have been out in full force – at airports, grocery stores, subways and more – telling Americans that the best way to prevent influenza and stay well during the flu season is by getting a flu shot.
It remains to be seen how effective (or ineffective) this year’s flu vaccine will be, but in the meantime research has shown that much remains to be understood about the potential negative effects of frequent vaccination on human health.
Getting Flu Shots Regularly May Make You More Susceptible to the Flu
Data collected from Canada and Hong Kong during 2009-2010 showed that people who received the seasonal flu vaccine in 2008 had twice the risk of getting the H1N1 “swine flu” compared to those who hadn’t received a flu shot.4,5,6
ABC News reported at that time that such shots may actually set you up for less “broad” protection than if you get, and recover from, a natural infection.7
It’s also been shown that getting previous flu shots led to a blunting effect or “interference” that left the recipient less protected from certain influenza strains in later years
In fact, research in the journal Clinical Infectious Diseases found that vaccine-induced protection against influenza was greatest among those not vaccinated during the prior five years.8
In other words, the long-term effects of getting an annual flu shot are completely unknown, but it appears this strategy may be backfiring, leaving those who have been vaccinated annually less protected than those who have not been frequently vaccinated.
Dr. Michael Gardam, director of infection prevention and control at Toronto’s University Health Network, told CBC News:9
“People do not have a good explanation for why The idea basically is that your immune system is occupied elsewhere. It would be like getting the swirling ball of death on your Mac where your operating system is doing something else rather than opening the file.”
Dr. Danuta Skowronski, a Canadian researcher who conducted the original study discovering individuals with a history of annual seasonal flu shots increased their risk of infection with pandemic H1N1 influenza, noted that the findings are so new that “policy-makers have not yet had a chance to fully digest them or understand the implications.”10
Unfortunately, instead of warning the public that annual flu shots may carry unknown risks
