Nurse who fainted after getting Pfizer-BioNTech COVID-19 vaccine has a history of fainting episodes; does not mean the vaccine is unsafe

Fainting, also known as syncope, can occur after vaccination. It is usually harmless in itself, although it can lead to injuries if the affected person falls, which can happen if they are not sitting or lying down at the moment of fainting. Episodes of vasovagal syncope are often triggered by pain and/or anxiety, which can lead to changes in heart rate and blood flow, resulting in a temporary loss of consciousness. The sight of blood or a needle can also trigger vasovagal syncope. Fainting following vaccination is not necessarily indicative of problems with the vaccine itself.

The U.S. National Childhood Vaccine Injury Act does not stop people from suing vaccine manufacturers

Multiple studies have established that vaccines are safe and not associated with increased rates of autism, cancer, or infertility. The National Childhood Vaccine Injury Act does not prevent people from suing a vaccine manufacturer for vaccine injuries. The U.S. Department of Health Resources and Services Administration explains that “Although the Act provides liability protections to vaccine manufacturers and vaccine administrators who administer covered vaccines in many circumstances, these protections are not absolute.” For instance, the Act does not provide manufacturers protection “when an individual files a petition and is requesting damages of $1,000 or less.” These protections also don’t hold if a vaccine manufacturer has been shown to be negligent.

Study on vaccinated and unvaccinated children used a dubious metric for comparing disease incidence in both groups

Large-scale, reputable studies did not find a greater incidence of adverse health outcomes in vaccinated children compared to unvaccinated children. The authors of the study cited as the basis for this claim created a new metric that was not validated as a reliable proxy indicator to compare the incidence of illness in vaccinated and unvaccinated children. Due to this, the conclusions of the study are questionable.

Significant methodological flaws in a 2020 study claiming to show unvaccinated children are healthier

Large-scale, reputable studies have not found a greater incidence of adverse health outcomes in vaccinated children compared to unvaccinated children. A significant problem with the single study cited in this claim is its failure to control for differences between vaccinated and unvaccinated children, such as healthcare-seeking behavior, which can factor into health outcomes. Furthermore, the study used patient data from handpicked pediatric clinics only, which are not representative of the general population.

Vaccines do not cause mercury toxicity or autism, contrary to claim in London Real video

Vaccines do not cause autism or mercury toxicity. The amount of mercury that infants receive through their diet is more than twice the amount ever contained in vaccines. Scientific evidence shows that autism spectrum disorder (ASD) arises through a combination of genetics and environment. Twin studies demonstrate a strong heritable component to ASD, with heritability estimates ranging from about 30 to 90%. Many genes involved in ASD risk are associated with brain and neuronal development.
