FactCheck.org’s SciCheck feature focuses exclusively on false and misleading scientific claims that are made by partisans to influence public policy. It was launched in January 2015 with a grant from the Stanton Foundation. The foundation was founded by the late Frank Stanton, president of CBS for 25 years, from 1946 to 1971.
There is no link between COVID-19 vaccination and an increased risk of stillbirth, despite such claims online. In fact, vaccination has been shown in multiple studies to reduce the risk of stillbirth by protecting pregnant people and their babies from the coronavirus.
A 62-year-old bodybuilder who had heart disease died after contracting COVID-19. But vaccine opponents are falsely suggesting that he died from the COVID-19 vaccine. He didn’t. He’d been vaccinated 18 months before his death.
A rigorous vaccine safety monitoring system has shown that the COVID-19 vaccines are safe and only rarely have serious side effects. But an article shared on social media falsely says that CDC data show more than 18 million people “were injured so badly” by a Pfizer/BioNTech or Moderna COVID-19 vaccine “that they had to go to the hospital.”
Seasonal influenza vaccines are recommended because they help prevent illness and death. Dr. Robert Malone incorrectly suggested that the annual shots are only given in the U.S. to support vaccine manufacturing in case of an influenza pandemic.
To study the role of the spike protein in the severity of COVID-19 illnesses, researchers exposed 10 mice prone to develop severe disease to a hybrid version of the virus. Eight mice died. Social media posts say researchers created a dangerous new variant with an “80 PERCENT Kill Rate,” potentially leaving the false impression that this pertains to humans. Also, the hybrid virus used in the study had a lower mortality rate than the original virus had on mice.
Vaccines are added to the Centers for Disease Control and Prevention’s immunization schedule after consultation with an outside advisory group and when the benefits outweigh the risks. Contrary to claims from Tucker Carlson and others, the COVID-19 vaccines will not become mandatory in schools just by being added to the CDC schedule. States and local districts make those determinations.
The COVID-19 vaccine clinical trials were designed to study the vaccine’s safety and efficacy in preventing symptomatic disease, not transmission. But online publications now misleadingly present the fact that the Pfizer/BioNTech vaccine was not tested for transmission as a “shocking admission” and proof that the company and the government lied.
The state of Florida recently announced that it was no longer recommending that younger males receive mRNA COVID-19 vaccines, based on an unpublished analysis that purportedly found an increased risk of cardiac-related death following vaccination. But experts who specialize in the unique method used in the analysis say it was not properly done — and even if it had been, the findings would not mean that individuals should not get vaccinated.
No evidence suggests it’s dangerous for babies to consume breast milk from mothers who get vaccinated against COVID-19. Online posts, however, have pointed to a study that found temporary, trace amounts of vaccine mRNA in milk after vaccination to claim that the vaccines are unsafe.
The Centers for Disease Control and Prevention hosted an online seminar about the treatment of blood clots, which is expected to grow as the U.S. population ages and the obesity rate increases. But some vaccine opponents misrepresented the webinar to falsely suggest that the projected rise in blood clots is related to the COVID-19 vaccines.
