AFP's fact-check service debunks misinformation spread online. Here are some of our recent articles on false claims in the United States: Social media posts claim that there is no "office of president-elect" and accuse Joe Biden of appropriating the title. This is misleading; nearly-complete election results confirm Biden's victory, and the office of the president-elect -- though an informal term -- is not new. US presidents including Donald Trump used it in press briefings during transition phases in the past. Videos viewed hundreds of thousands of times claim President Donald Trump won the election in a landslide but it was rigged so that he lost by millions of votes. This is false; Democrat Joe Biden is projected to have won the Electoral College and the popular vote, government experts and independent monitors have vouched for the ballot's integrity, and even Republicans have criticized the lawyer who made the claims without ever providing evidence. Instagram and Facebook posts claim that the Pediarix vaccine, which protects against polio and other diseases, injects an unsafe amount of aluminum into infants. The claim is false; Pediarix was tested for safety and has been approved for use since 2002, aluminum increases the immune response to the vaccine, and the amount contained in a dose is less than that ingested by infants via breast milk or formula. 1. 2. 3. afp
