AFP's fact-check service debunks misinformation spread online. Here are some of our recent articles about inaccurate claims in the United States: Social media posts claim that people who have received a Covid-19 shot are ineligible to donate plasma to the American Red Cross because the vaccine destroys antibodies -- an assertion the non-profit organization says is false. An online video says the Moderna Covid-19 vaccine contains a cancer-causing ingredient that is not fit for human use. But the warning in the data sheet used to "prove" the claim is about chloroform, a toxic compound that regulators do not list as being in the vaccine. Social media posts claim Hamas, the Gaza Strip's Islamist rulers, bought "weapons of mass destruction" with $150 million provided by US President Joe Biden. But while Washington announced that amount of funding for the United Nations agency for Palestinian refugees, both the aid organization and the US State Department say the money is subject to strict monitoring to prevent abuses, and it is for five locations, not just Gaza. Facebook posts claim a whistleblower revealed that millions of votes were changed to favor President Joe Biden by election technology company Dominion, with some attributing the information to former New York City mayor Rudy Giuliani. This is false; Dominion says there is "no truth" or evidence of such a claim, while US federal investigators have not found any credible cases of such fraud in the 2020 election. 1. 2. 3. 4. afp
