For six months, the MHRA and other national regulators have been sitting on a Pfizer report about Covid vaccine safety. Worryingly, the abstract which I have just found online doesn’t look good at all:
- the vaccinated cohort have at least 23-40% higher risk of some heart-related conditions; and
- the risk is higher than in Pfizer’s previous report (i.e., it is increasing over time since vaccination).
The report in question is Pfizer’s report C4591021 ‘Interim Report 5’ dated March 12th 2024. It is a Post Authorisation Safety Study (PASS) of Pfizer’s Covid vaccine. In summary, national regulators routinely require pharmaceutical manufacturers to conduct PASS studies as a condition of authorisation of most new medicines. The regulators provide data to the manufacturer covering millions of patients registered in national healthcare systems. The manufacturer then conducts analysis to determine whether the medicine has increased the risk of specified health conditions.
