The Rest of the Story
The following claim has been going around the crackpot-American community:
A review of 51 studies involving 260,000 kids age 6 to 23 months found no evidence that the flu vaccine is any more effective than a placeboWhen we try looking for the study in question, we see:
From RCTs, live vaccines showed an efficacy of 82% (95% confidence interval (CI) 71% to 89%) and an effectiveness of 33% (95% CI 28% to 38%) in children older than two compared with placebo or no intervention. Inactivated vaccines had a lower efficacy of 59% (95% CI 41% to 71%) than live vaccines but similar effectiveness: 36% (95% CI 24% to 46%). In children under two, the efficacy of inactivated vaccine was similar to placebo.In other words, the same study they're citing shows that the vaccines are beneficial for children older than two … but they don't mention that, for some reason.
