Medical director of Pfizer UK, Dr Berkeley Phillips tweeted a promotion of the Pfizer mRNA product back in November 2020. The promotion of an unlicensed medicine or unauthorised indication is a criminal offence and can receive a penalty of a fine or imprisonment for up to two years. The tweet also breached the code of practice set out by the Prescription Medicines Code of Practice Authority (PMCPA), according to Dr Carl Heneghan and Dr Tom Jefferson. However, Pfizer’s penalty was a fine of just £34,800 which equates to 0.00005% of Pfizer’s 2021 revenues.
