I came across an excellent example of the confirmation bias that is enforced by and contributes to crowd-think in fields like Global Warmism and Vaccinism.

Increased risk of noninfluenza respiratory virus infections associated with receipt of inactivated influenza vaccine.

ABSTRACT: We randomized 115 children to trivalent inactivated influenza vaccine (TIV) or placebo. Over the following 9 months, TIV recipients had an increased risk of virologically-confirmed non-influenza infections (relative risk: 4.40; 95% confidence interval: 1.31-14.8). Being protected against influenza, TIV recipients may lack temporary non-specific immunity that protected against other respiratory viruses.

Nice abstract, short and to the point. Only, when they say in the last sentence of the abstract “temporary”, that’s a euphimism for “a defect in their immune system that persisted as long as we studied them, and we hope it eventually goes away”, and when they say “Being protected against Influenza”, they are saying something their study did not in fact provide statistically significant evidence for. What it did find was they got 4 times as many non-flu respiratory illnesses.

If vaccines are punching gaps in immune systems, how long till viruses evolve to exploit the weaknesses?
