Perhaps we wouldn't have had the news, pretending that there was no effect, and if there was, correlation is not causation, and then saying as little as 5 months ago that there may be an effect but that any effects on menstruation only lasted one day at the most [1]. Just be honest - dishonesty like this breeds anti-vaxxers.
