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.
Among the 115 participants who were followed up, the median duration of follow-up was 272 days (interquartile range, 264–285 days), with no statistically significant differences in age, sex, household size, or duration of follow-up between TIV and placebo recipients (Table ). We identified 134 ARI episodes, of which 49 met the more stringent FARI case definition. Illnesses occurred throughout the study period (Supplementary Appendix Figure 1). There was no statistically significant difference in the risk of ARI or FARI between participants who received TIV and those who received placebo, either during winter or summer 2009 (Table ).

“Young adult small-breed neutered dogs that received multiple vaccines per office visit were at greatest risk of a VAAE {vaccine-associated adverse events} within 72 hours after vaccination.”

“With regard to the reporting in VAERS, the timing of a disease closely following a vaccination and lack of any other obvious cause are most often the only criteria of potential significance for a suspected adverse reaction.”

“Meta-analysis showing that formaldehyde — a known carcinogen and and ingredient in most childhood vaccines — exposure causes reproductive and developmental harm, including spontaneous abortions in pregnancy at low doses. Most studies included are in animals that can have similar drug reactions as humans because human toxicity studies are not ethical.”

“There have been some recent conceptual developments in vaccine ‘herd immunity’ or ‘herd protection’ that address the complexities of imperfect immunity.”
