There were 25,000 cases of microcephaly in the USA last year, up from 400 a few years back. Without any damn Zika, or even an especially bad mosquito season. What CHANGED was the DTaP shot (or was it TDaP?) Anyway, it was given to pregnant women just at the point in 2014 where it would have been correlated with the sudden increase in microcephalic births six months later – just like what happened in 2015 in South America. The 2.4% incidence of Zika in babies born with microcephaly in Brazil is prima facie evidence that there is NO association between the two!
