What percentage of Pfizer vaccine side effects in Malaysia are non-serious?

Question

Accepted Answer

Majority of Pfizer Vaccine Side Effect Reports in Malaysia Are Non-Serious

A total of 94.2% of the 20,131 reported side effects following immunisation (AEFI) for Pfizer's Comirnaty Covid-19 vaccine in Malaysia were classified as non-serious. These reports represent a small fraction of the over 44.8 million doses administered nationwide, indicating an overall favourable safety profile for the vaccine.
Non-Serious Side Effects Are Temporary and Common

The vast majority of reported side effects, at 94.2%, were categorised as non-serious. These are typically temporary reactions that do not pose a significant health risk. Common symptoms experienced by individuals included fever, pain at the injection site, headache, muscle aches, and fatigue, which are consistent with expected post-vaccination responses.
Serious Side Effect Reports Constitute a Small Minority

Out of the total 20,131 AEFI reports, only 5.8%, or 1,162 cases, were classified as serious. According to the World Health Organisation's classification, serious AEFI are those that lead to hospital admission, pose a risk to health, cause significant loss of capacity, or require intervention to prevent permanent damage or death.
Investigations Reveal Minimal Serious Vaccine-Related Incidents

Following thorough investigation and evaluation by the Covid-19 Vaccine Pharmacovigilance Special Committee, only one case of myocarditis was identified as potentially related to the Comirnaty vaccine. This finding is part of the comprehensive review of the 1,162 serious AEFI reports received.
Reporting Rates Align with Global Data and Demonstrate Acceptable Safety

The rates of adverse event reporting in Malaysia are consistent with international findings. A Safecovac study, conducted with the Institute for Clinical Research, found the Comirnaty vaccine's safety profile to be acceptable, with no increased risk observed for conditions such as myocarditis, pericarditis, acute facial paralysis, stroke, and myocardial infarction within 21 days of administration. The overall assessment confirms that the benefits of the Comirnaty vaccine in Malaysia continue to outweigh the risks.
