Ventilators can be lifesaving for critically ill COVID-19 patients. A social media claim that a new study shows ventilators killed “nearly all” COVID-19 patients is “quite wrong,” according to the study’s co-author. Ventilator-associated complications can contribute to deaths, but patients are typically put on ventilators when they would otherwise die.
Outside of long COVID or very severe cases, most research suggests COVID-19 doesn’t cause lasting damage to the immune system. A few studies have found evidence of some possible damage, but nothing as severe as an immunodeficiency. People on social media, however, are misinterpreting a recent study to incorrectly claim COVID-19 is HIV-like.
People online are touting the results of a Cochrane review to incorrectly claim that it shows masks “don’t work” against the coronavirus. But the primary conclusion of the review is that it’s uncertain from randomized controlled trials whether mask interventions in the community help slow the spread of respiratory illnesses.
Vaccination and infection both provide protective immunity to COVID-19, particularly against severe disease. But gaining immunity through infection is far riskier than vaccination. Posts citing a new Lancet study omit that important context and also misleadingly claim the study shows immunity after infection is superior to vaccination immunity.
Scientists say the experiments Pfizer has performed on the coronavirus are standard for the industry. Baseless claims that the company is mutating the virus for profit, however, have been circulating since the release of a popular undercover video from the conservative activist group Project Veritas.
A vaccine safety surveillance study from the Food and Drug Administration has been misrepresented online. The paper did not establish a link between the Pfizer/BioNTech COVID-19 vaccine and blood clots, as some have claimed — and to date, other, more robust research has not identified such associations.
A blood transfusion from a vaccinated person doesn’t transfer the inoculation to an unvaccinated person. But high-profile purveyors of misinformation have been promoting the long-standing false claim that it does.
What appear to be ordinary postmortem blood clots are held up in a viral online video as supposed evidence that there’s a depopulation plot underway using COVID-19 vaccination to kill people. There’s no evidence for this theory. The hourlong video also repeats numerous falsehoods that have previously been debunked.
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.
