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.

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.

An ONS study didn’t show that the COVID-19 vaccine caused a higher risk of heart-related deaths in women, contrary to viral claim

COVID-19 vaccination provides the best protection against COVID-19. Like any other vaccine, COVID-19 vaccines can cause side effects, but most of them are mild and disappear after a few days. While serious reactions to vaccination can occur, they are very rare. Current evidence indicates that the potential risks of vaccination don’t outweigh their benefits at preventing severe COVID-19 and death.

Scientific evidence shows that COVID-19 vaccines don’t increase the risk of heart attacks, contrary to Russell Brand video

Multiple scientific studies have documented the detrimental effects of SARS-CoV-2 infection on the heart, suggesting that COVID-19 is a significant contributor to the increase in heart attacks among young people during the pandemic, although other factors, such as a delay in care due to lockdowns and healthcare disruption, could also have contributed to it. Studies show that the benefits of COVID-19 vaccines outweigh their risks, and that vaccinated people don’t have a greater risk of heart attack compared to unvaccinated people.

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.

Baseless claim that COVID-19 vaccines killed more than 200,000 comes from flawed BMC Infectious Diseases study

Despite claims made on social media, a study published by the peer-reviewed journal BMC Infectious Diseases doesn’t actually provide the necessary scientific evidence for its claim that nearly 300,000 people died from COVID-19 vaccines. This estimate is based on a survey of about 2,800 people, but doesn’t involve verifying the accuracy of survey responses by examining medical records. As such, the study doesn’t offer a reliable estimate of deaths related to the COVID-19 vaccines.

Video by John Campbell comparing historical and COVID-19 vaccines misleads on vaccine safety

Multiple peer-reviewed published studies have shown that the benefits of COVID-19 vaccination outweigh its risks. Benefits from vaccination take longer to appear compared to harms, which usually appear within the first six weeks following vaccination. Consequently, studies that aim to reliably compare the risks and benefits of vaccination require time to obtain a complete picture.
