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.
Studies have found that COVID-19 increases the risk for heart complications, and that the benefits of COVID-19 vaccination outweigh the risks for males and females in all age groups. Social media posts, however, have misinterpreted and publicized a criticized study that claims to have identified a correlation between emergency calls for cardiac events and the vaccination rate in Israel.
A string of unexplained hepatitis cases in children has been reported in the U.S. and in other countries. The cause is not yet known, but the top suspect so far is a strain of adenovirus. Contrary to some social media posts, there is no evidence that COVID-19 vaccination is involved. Most of the children are too young to even qualify for the vaccine.
The American Red Cross and other blood collectors in the U.S. strongly encourage everyone who is feeling healthy to donate blood, including people who have received a COVID-19 vaccine. But a social media post falsely implies the organization does not use the blood from vaccinated people.
A report from the Centers for Disease Control and Prevention found that side effects such as a sore arm or headache following a booster dose of the mRNA COVID-19 vaccines were less frequent than after the second dose. But a Facebook video from a chiropractor misrepresents the report’s findings, the systems that record adverse events and the availability of information on those events.
A Pfizer document recently released by the Food and Drug Administration describes adverse events reported following vaccination and attests to the continued safety of the company’s COVID-19 vaccine. A popular video and other online posts, however, incorrectly imply that the vaccine caused the events.
The Centers for Disease Control and Prevention and Pfizer tweeted in February about the dangers of blood clots in veins, which are relatively common and affect as many as 900,000 Americans each year. A story shared on social media, however, misleadingly linked those public health reminders to the COVID-19 vaccines.
Rare cases of myocarditis have been reported following the mRNA COVID-19 vaccines, particularly among young males after a second dose. Most cases resolve quickly without the need for advanced therapies, although research on any potential long-term effects is ongoing. Nonetheless, the benefits of vaccination outweigh the risks in all populations, even in young males.
