Flu Shots Increase Susceptibility to Common Cold

Broadcast Message

Peter A. McCullough, MD, reports that after skipping the flu vaccine for three years, he experienced fewer respiratory illnesses. He recalls taking 40 flu shots during training and questions whether the vaccine could weaken the immune system. A 2012 study by Cowling et al. found that children receiving the flu vaccine had a 4.4-fold increase in viral infections within two weeks compared to those who received a placebo.

Flu Shots Increase Susceptibility to Common Cold Randomized Trial Demonstrates Tradeoff Wed, 04 Dec 2024 10:41:48 GMT https://petermcculloughmd.substack.com/p/flu-shots-increase-susceptibility By Peter A. McCullough, MD, MPH

For the past three years I have skipped the influenza vaccine and have noticed progressively fewer viral upper respiratory tract illnesses or common colds. In decades prior I had taken forty flu shots as requirements in medical school, residency, fellowship, and medical staff. Could the flu shot weaken or misdirect the immune system on a regular basis?

In 2012, Cowling et al performed a prospective, double-blind randomized placebo controlled trial in children ages 6-15 years to who received either the 2008–2009 seasonal trivalent influenza inactivated vaccine (TIV; 0.5 mL Vaxigrip; Sanofi Pasteur) or placebo. The results were stunning. While summer and winter colds were not statistically different, proven viral infections within two weeks of the shot confirmed by PCR testing were 4.4-fold greater in those who took the flu shot.
