"However, another authoritative source British National Formulary/National Institutes for Healthcare Excellence (BNF NICE) listing this season's products states that all the suspensions "may contain" thiomersal. The position is ambiguous to say the least."
A row has apparently blown up in the media between a mega star that I have never heard of, Calvin Harris, with 12.7 million twitter followers and British health officials. Harris has apparently claimed that there is mercury in the 2017 UK flu shot. No such claim I would like to make clear has ever been made on this website. While it is difficult to find out exactly which products are being given I have just checked through the ingredients of ten products I was able to identify and none had mercury, thiomersal or thimerosal listed.
