Studies have repeatedly found that COVID-19 vaccination does not increase the risk of miscarriage. Bogus claims that 44% of pregnant women in the Pfizer/BioNTech COVID-19 vaccine trial miscarried rely on a faulty tally of miscarriages that counted each miscarriage twice and included miscarriages from people in the placebo group.
After a long delay marred by manufacturing troubles, a COVID-19 vaccine from Novavax became the fourth such vaccine authorized in the U.S. We review how it works and how it’s different from its competitors.
It’s estimated that COVID-19 vaccines have saved millions of lives, but false claims continue to cast doubt on their safety and efficacy. One such claim that has spread around the world falsely suggests that three Canadian doctors died from the shots. But they each died of a long-term illness unrelated to the vaccines.
Viral claims have repeatedly misrepresented unverified data from a U.S. vaccine safety system that encourages reports of any potential side effects — whether they’re likely to be caused by the vaccine or not. Now we’re seeing the same phenomenon with a similar system in Germany. Some have wrongly claimed Germany found the COVID-19 vaccine caused “serious side effects” in a large number of people.
The mRNA COVID-19 vaccines teach the immune system to recognize and fight the coronavirus, greatly reducing the likelihood of severe disease if a person is infected. There is no evidence the vaccines impair immunity, as some, including Fox News’ Tucker Carlson, have baselessly claimed.
In young children, the Pfizer/BioNTech and Moderna COVID-19 vaccines are expected to primarily protect against severe disease. Both shots successfully met the set benchmarks for vaccine effectiveness, which involved comparing antibody responses to those of adults. Online posts critical of government recommendations for the pediatric vaccines, however, fail to mention these essential data.
Children under 5, including those as young as 6 months of age, are now able to be vaccinated against COVID-19. Here, we explain what’s known about the two coronavirus vaccines for the youngest children.
An executive at the German pharmaceutical company Bayer referred to mRNA vaccines used against COVID-19 as an example of innovation in biotech at the World Health Summit 2021. But a website post takes the executive’s words out of context to falsely claim he said the vaccines are gene therapy.
Pop star Justin Bieber announced he has Ramsay Hunt syndrome, a form of facial paralysis caused by a reactivation of the virus that causes chickenpox. Social media posts have claimed his condition was caused by COVID-19 vaccination, but there is no established link between vaccination and the syndrome. Some posts have also baselessly claimed vaccination was behind a mini-stroke suffered by Bieber’s wife, Hailey.
Sudden Arrhythmic Death Syndrome, or SADS, has been studied for decades and is caused by genetic heart problems. But social media posts suggest, with no evidence, that SADS is related to COVID-19 vaccines.
