The fact-check does a good job of showing that the claim all vaccines are based on fake data is false. It points out that while there were problems with things like the Wakefield study, those were rare and have been proven wrong. It also uses trusted sources like the FDA and Johns Hopkins to back up its points. However, it could be clearer when talking about mRNA vaccines. Not all vaccines use mRNA only some newer ones, like the COVID-19 vaccine. It could also explain more about how vaccines are tested and approved to show how thorough the process is. Finally, it could mention more about the real harm caused by vaccine misinformation, like outbreaks of diseases when people refuse to get vaccinated. Overall this a pretty solid factcheck, with really credible and reliable sources, but could improved in some areas.
