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.
Expanded reporting requirements and intense scrutiny of the hundreds of millions administered COVID-19 vaccine doses have driven record reporting of potential side effects to one of the government’s vaccine safety monitoring systems. Social media posts, however, have misleadingly insinuated that the increase in reports means the vaccines are unsafe.
Social media posts are misrepresenting an old photo from France by suggesting the sea of people in the streets shows “[p]eople are waking up against vaccine tyranny.” The photo actually shows a celebration in Paris after France won the 2018 World Cup.
Federal vaccine monitoring systems have identified no safety concerns with the COVID-19 vaccines for pregnant people. Preliminary Centers for Disease Control and Prevention data show that miscarriage is not more frequent than expected in vaccinated people. Online posts, however, falsely contend that such data, as reported in a CDC publication, show an 82% miscarriage rate.
The COVID-19 vaccines have been shown in trials and real-world application to be safe and effective. But a paper shared widely online claimed that vaccines cause two deaths for every three lives saved. Experts say the analysis misinterpreted data and was flawed — and it has now been retracted by the journal that published it.
There is no evidence to indicate that the spike proteins generated by human cells following vaccination are a toxin or that they circulate in the body and damage tissues, contrary to what a Canadian virus immunologist recently claimed.
Clinical trials and medical studies have indicated that the COVID-19 vaccines are safe for pregnant people. But online posts misrepresent unverified reports submitted to vaccine monitoring systems in the U.S. and Europe to misleadingly suggest “920 women” lost babies because they received COVID-19 vaccines.
The COVID-19 vaccines have been the subject of peer-reviewed studies that found they were effective and safe, but a meme has been circulating on social media falsely claiming that no such studies have been conducted.
The COVID-19 vaccine from Moderna uses an ingredient called SM-102 to deliver the mRNA that carries instructions for how to develop antibodies against the novel coronavirus. A widely shared video is now spreading the falsehood that SM-102 is harmful, but the warning label it shows is for chloroform, not SM-102.
A Food and Drug Administration presentation on monitoring the safety of COVID-19 vaccines listed possible adverse events the agency might track. But an Instagram post misrepresents the document, falsely claiming it shows the vaccines are known to cause harmful side effects — including death.
