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.

Q&A on Reducing COVID-19 Risk for Elderly, Immunocompromised

Q&A on Reducing COVID-19 Risk for Elderly, Immunocompromised

While the risks associated with COVID-19 generally have decreased over time due to prior exposure to the vaccines and the virus, some people remain at elevated risk, such as the elderly and immunocompromised. The updated COVID-19 vaccines and, in some cases, a new monoclonal antibody can provide increased protection for this group.

Posts Raise Unfounded Concerns About Aluminum in Vaccines

Small amounts of aluminum have been used for many decades to strengthen the immune response to vaccines. Exposure to high levels of aluminum has been associated with brain and bone problems, but there is no evidence that the level of exposure provided by vaccines leads to such toxicity, contrary to social media claims.

Social Media Posts Misinterpret Biden on mRNA Cancer Vaccines

Social Media Posts Misinterpret Biden on mRNA Cancer Vaccines

COVID-19 vaccines are not “being used to cure cancer,” as social media posts falsely claim, misinterpreting President Joe Biden’s reference to mRNA cancer vaccines during his State of the Union address. Biden was referring to the mRNA technology used to make the COVID-19 vaccines and being studied by researchers to treat cancer.

Explaining the New CDC Guidance on What To Do if You Have COVID-19

Explaining the New CDC Guidance on What To Do if You Have COVID-19

Q: Is one day isolation sufficient to stop forward transmission of COVID-19? 

A: People with COVID-19 could potentially transmit it to others well beyond a day after developing symptoms or testing positive. New guidance from the CDC advises people to isolate until they have been fever-free and with symptoms improving for at least 24 hours, and then take precautions for five days, which covers the period when “most people are still infectious.”

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.
