Florida’s Surgeon General Spins State COVID-19 Vaccine Comparison Study

Florida’s Surgeon General Spins State COVID-19 Vaccine Comparison Study

A new analysis of data from Florida found a higher risk of mortality in those receiving the Pfizer versus the Moderna COVID-19 vaccine in the year after a first dose. It does not establish that the Pfizer vaccine was dangerous or caused deaths, contrary to suggestions by the state’s surgeon general or statements by online purveyors of vaccine misinformation.

Florida’s 2024-2025 COVID-19 Vaccine Guidance Misunderstands, Distorts Existing Science

Florida’s 2024-2025 COVID-19 Vaccine Guidance Misunderstands, Distorts Existing Science

An abundance of evidence indicates the mRNA COVID-19 vaccines are remarkably safe and work well to protect against severe disease. But last month, the state of Florida issued updated vaccine guidance advising “against the use” of the shots entirely — even for people who are older and at higher risk of severe disease. Experts say the advice is ill-informed and “illogical.”

Still No Evidence COVID-19 Vaccination Increases Cancer Risk, Despite Posts

Still No Evidence COVID-19 Vaccination Increases Cancer Risk, Despite Posts

It has not been shown that COVID-19 vaccines cause or accelerate cancer. Yet opponents of the vaccines say a new review article “has found that COVID-19 mRNA vaccines could aid cancer development.” The review conclusions are mainly based on the misinterpretation of a study on mRNA cancer vaccines in mice.

Study Largely Confirms Known, Rare COVID-19 Vaccine Side Effects

Study Largely Confirms Known, Rare COVID-19 Vaccine Side Effects

An international study of around 99 million people confirmed known serious side effects of COVID-19 vaccination. It also identified a possible relationship between the first dose of the Moderna vaccine and a small risk of a neurological condition. Social media posts about the study left out information on the vaccines’ benefits and the rarity of the side effects.

Posts Misrepresent Mouse Study of Pangolin Virus

A study showed a type of lab mouse is highly susceptible to a coronavirus derived from pangolins, a scaly, cat-sized mammal. This doesn’t mean the virus is dangerous to humans. The virus is related to the one that causes COVID-19 but did not descend from it, contrary to claims that it is a “mutant COVID-19 strain.” Nor did scientists “craft” the virus.

COVID-19 Vaccination During Pregnancy Is Safe, Has Multiple Benefits

COVID-19 Vaccination During Pregnancy Is Safe, Has Multiple Benefits

Being vaccinated against COVID-19 helps protect pregnant people from severe COVID-19. When given during pregnancy, the vaccines can also reduce the risk of hospitalization from COVID-19 early in a baby’s life. A new study adds to the evidence that vaccination during pregnancy is safe for babies, contrary to social media and online claims.

COVID-19 Vaccines Have Not Been Shown to Alter DNA, Cause Cancer

COVID-19 Vaccines Have Not Been Shown to Alter DNA, Cause Cancer

Small amounts of DNA from the manufacturing process may remain in the mRNA COVID-19 vaccines. Purification and quality control steps ensure any leftover DNA is present within regulatory limits. There isn’t reason to think that this residual DNA would alter a person’s DNA or cause cancer, contrary to claims made online.

Posts Falsely Push Bill Gates-Connected ‘Air’ Vaccine Conspiracy

Inhalable or spray versions of mRNA COVID-19 vaccines are still in development and don’t have regulatory approval. Posts online are distorting recent research from Yale University to falsely claim that governments have approved such products to mass vaccinate people without their consent in a plot involving Bill Gates.

Posts Push Unproven ‘Spike Protein Detoxification’ Regimen

Serious side effects after COVID-19 vaccination are rare, and there isn’t evidence people need to undergo a “spike protein detoxification” regimen after getting vaccinated, contrary to claims made online. Nor has such a regimen been shown to help people recover from long COVID, or long-term health problems after having COVID-19.

COVID-19 Vaccines Have Not Been Shown to Cause ‘Turbo Cancer’

COVID-19 Vaccines Have Not Been Shown to Cause ‘Turbo Cancer’

People with cancer are particularly vulnerable to severe disease and death from COVID-19. Vaccines provide needed protection. It has not been shown that COVID-19 vaccines cause or accelerate cancer. Nor does a recent paper about a mouse that died of lymphoma “prove” that the Pfizer/BioNTech vaccine induced “turbo cancer,” contrary to social media claims.
