Multiple studies show that COVID-19 vaccines don’t cause pregnancy or fertility problems, despite widespread claims on social media

Pregnant women are more likely to develop severe COVID-19 compared to non-pregnant women. COVID-19 also increases the risk of pregnancy complications, including preterm delivery and stillbirth. COVID-19 vaccines can prevent these risks and aren’t associated with any safety issues during pregnancy. Therefore, public health authorities recommend that pregnant women get a COVID-19 vaccine.

No evidence that COVID-19 vaccines cause “fibrous lung clots”, contrary to claim by Jane Ruby

A rare medical condition called plastic bronchitis can result in the formation of gelatinous masses in the airways. These masses, called bronchial casts, can replicate the shape of the airways in the lungs. Plastic bronchitis, which was identified in the 1800s, can be due to several causes, including infection or leaking of lymphatic fluid into the lungs. This condition was already identified in the 1800s and there isn’t scientific evidence that shows COVID-19 vaccines cause plastic bronchitis.

Cases of severe acute hepatitis of unknown origin in children are unrelated to COVID-19 vaccines

Since October 2021, almost 200 cases of a severe acute hepatitis of unknown origin have been detected in young children from several European countries and in the U.S. One of the disease’s most striking features is its unusual severity, with 10% of the cases requiring liver transplantation. The leading hypothesis so far is that an adenovirus infection is causing or contributing to the disease, but health authorities are continuing to investigate other potential causes, including exposure to a toxic agent or infection by a novel pathogen.

Comparing SARS-CoV-2 infection rate of vaccinated and unvaccinated populations doesn’t reflect the real COVID-19 vaccine effectiveness

Vaccinated and unvaccinated populations may differ in many characteristics, such as age, population size, social behavior or health seeking behavior. These differences must be taken into consideration when comparing the SARS-CoV-2 infection rates between vaccinated and unvaccinated populations. Failure to do so may lead to biased conclusions. Studies accounting for these differences showed that COVID-19 vaccines effectively reduce the risk of getting sick.

Higher myocarditis risk after COVID-19 than mRNA vaccination; contrary to Peter McCullough’s claim, young persons decrease their risk by getting vaccinated

Myocarditis, an inflammation in the heart muscle, is typically caused by viral infections. In rare instances, myocarditis can also occur after COVID-19 vaccination. During the global COVID-19 vaccination campaign, the mRNA vaccines have been linked to rare cases of post-vaccine myocarditis that are usually mild and resolve; these have occurred primarily in young males. On the other hand, COVID-19 itself carries a much higher risk of heart complications, including myocarditis. Moreover, the COVID-19 vaccines decrease the risk of COVID-19-related myocarditis, meaning that COVID-19 vaccination continues to be recommended to young persons.

COVID-19 mRNA vaccines are safe; they don’t alter our DNA and aren’t subjected to federal regulation on bioweapons

mRNA COVID-19 vaccines don’t meet the U.S. FDA criteria to be considered a form of gene therapy, as the vaccines don’t modify the genes of the vaccinated person. Furthermore, mRNA vaccines for COVID-19 don’t contain chimeric viruses nor produce chimeric organisms. COVID-19 vaccines aren’t subjected to federal regulation on biological agents and don’t turn the human organism into a bioweapons factory.

CDC’s COVID Data Tracker revised COVID-19 deaths downward, but more reliable mortality data still indicate that COVID-19 is a major cause of death in the U.S.

The U.S. Centers for Disease Control and Prevention (CDC) removed more than 70,000 deaths from its COVID Data Tracker, including 416 pediatric deaths. According to the CDC, this correction was required due to an algorithm error that mistakenly included deaths not due to COVID-19. That said, the downward revision of COVID-19 deaths in the COVID Data Tracker isn’t evidence that COVID-19 is less deadly than initially thought. On the contrary, the more reliable mortality data from the U.S. National Center for Health Statistics, which uses death certificate data, reports a COVID-19 death toll that exceeds that of the COVID Data Tracker.

Fox News article listing alleged mistakes in COVID-19 public health response mixes accurate information with unsubstantiated claims

The evolving nature of the COVID-19 pandemic and the lack of knowledge about SARS-CoV-2 made policymaking extremely challenging at the early stages of the pandemic. As scientists made discoveries and acquired new knowledge, public health policies changed accordingly. Contrary to the article’s claim that public health officials followed “medical dogma”, they adapted policies, and even reversed them when needed, based on our evolving knowledge about the virus. This is precisely how the scientific method is applied and is in fact the opposite of dogma. When scientists realize that the evidence doesn’t support their initial hypothesis, they acknowledge this and incorporate that new evidence into our understanding of the world. Gathering evidence, however, takes time, which is why policies also take time to catch up.

Assessing the effect of COVID-19 vaccines on mortality: a story of confounding factors and their role in COVID-19 misinformation

Introduction COVID-19 vaccines have been instrumental in our fight against the pandemic and our return to a normal life, thanks to their ability to reduce the number of cases, hospitalizations, and mortality. Their effectiveness against severe COVID-19 and death was proven in randomized controlled trials (RCT) that involved tens of thousands of people[1,2]. While RCTs … Continued
