Not only was this study covered up, a Pfizer commercial aired that recommends oral treatment for high risk groups including smokers without disclosure of potential side-effects or a list of studies that confirm the claims of the ad. I’n not sure what loophole makes this legal but maybe it is because the actual drug name is not spoken and that allows Pfizer to advertise without listing the side effects by saying “ask your doctor if an oral treatment is right for you?”
