Analysis of adverse event variation between Pfizer COVID-19 vaccine batches doesn’t indicate safety problems, contrary to claim by John Campbell

Even before COVID-19 vaccines existed, there was already a baseline rate of illness and death occurring in the general population. The occurrence of an adverse event after vaccination in itself doesn’t necessarily mean the vaccine caused the event. To determine whether vaccination alters the risk of such events, researchers need to compare the baseline rate and the rate in vaccinated people. Multiple scientific studies have shown that serious side effects following COVID-19 vaccination are rare and the benefits of vaccination outweigh the risks.

COVID-19 is caused by a virus, not snake venom; no snake venom in COVID-19 vaccines, contrary to claim by chiropractor Bryan Ardis

Scientific evidence gathered in different laboratories around the world has established that the coronavirus SARS-CoV-2 is the causative agent of COVID-19. Pregnant women are at a higher risk of developing severe COVID-19 and getting COVID-19 increases the risk of pregnancy complications, including miscarriage. Studies so far have shown that COVID-19 vaccines are highly effective at reducing the risk of severe disease and don’t increase the risk of negative pregnancy outcomes. The American College of Obstetricians and Gynecologists recommend that pregnant women get vaccinated against COVID-19.

Neurological adverse events are very rare after COVID-19 vaccination and less frequent than after SARS-CoV-2 infection

Incidental illnesses, including neurological conditions, occur regardless of vaccination. Individual case reports and data from vaccine surveillance systems are generally insufficient on their own to establish a causal link between these events and the vaccine, so further investigations are needed to determine whether a vaccine caused these events. Epidemiological studies show that neurological adverse events after COVID-19 vaccination are very rare, much rarer than after SARS-CoV-2 infection, suggesting that the benefits of COVID-19 vaccines outweigh this potential risk.

Peter McCullough makes multiple false, misleading, and unsupported claims about COVID-19 vaccine safety and efficacy in viral podcast

All available evidence from clinical trials and safety monitoring indicates that the COVID-19 vaccines are safe and not associated with a rise in medical conditions and mortality. COVID-19 vaccines are also safe and recommended for pregnant women, who are at a higher risk of severe COVID-19 and pregnancy complications associated with the disease. Furthermore, COVID-19 vaccines haven’t been shown to be toxic, making so-called “detoxes” unnecessary.

Vaccination recruits both the innate and adaptive immune system; COVID-19 vaccines are safe for children

Vaccination harnesses the capabilities of both the innate and adaptive arms of the immune system. Clinical trials and post-marketing studies showed that COVID-19 vaccines are safe for children. Although COVID-19 mRNA vaccines are associated with rare cases of myocarditis, post-vaccine myocarditis has a much better prognosis compared to COVID-19-associated myocarditis. The risk of myocarditis and future cardiovascular complications are higher with COVID-19. Therefore, COVID-19 vaccines’ benefits outweigh their possible risks even for children.

The Pfizer bivalent vaccines are very unlikely to increase the risk of ischemic stroke, contrary to claims on social media

COVID-19 bivalent vaccines are designed to provide protection against both the original SARS-CoV-2 and the Omicron variant. Safety signals from pharmacosurveillance systems aren’t enough to determine whether an actual risk exists. This requires additional investigation and comparison with other monitoring tools. The higher risk of stroke following vaccination detected in the VSD surveillance system hasn’t been confirmed in other systems nor in clinical studies.
