UK has a report with 53 pages of side effects on Pfizer vaccine but Pfizer dont even say anything about it. Pfizer has mentioned high efficacy, but does not highlight that it has many limitations and some groups were excluded from the trials. For Pfizer, I do not know whether u have done proper research or blindly follow what media has been telling u. If u truly believe these experts that say Pfizer vaccines have high effectiveness, then why until nw there is no mention of UK report on Pfizer adverse reactions? If u tell me the chances are very low for serious side effects, imagine the possibility of having any of side effects listed in the report. I wont tell u here. See it for yrself.
