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.”
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.
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.
COVID-19 vaccines have been found to be safe and effective in trials and real-world conditions. Yet an online video baselessly claims a French life insurer refused to pay benefits for a man who died after receiving the vaccine because the insurer deemed it “a medical experiment.” It also falsely claims that the same has happened in the U.S.
Retooled COVID-19 booster vaccines that target omicron subvariants of the coronavirus are now available in the U.S. Here, we answer questions about the new shots.
Denmark announced a plan for its fall COVID-19 vaccination drive, saying it will offer omicron-specific booster shots to high-risk individuals, including everyone 50 and over. But U.S.-based misinformation peddlers misleadingly suggest that means the shots are unsafe for those under 50. The Danish Health Authority said that is a misinterpretation.
As the virus that causes COVID-19 has evolved, the vaccines have become less effective in preventing symptomatic infection while remaining highly effective in preventing severe disease and death. This shift has been misrepresented by anti-vaccine influencers who falsely claim that it means the vaccines don’t work and have been ineffective all along.
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.
