Antivaxxers frequently make the false claim that mRNA-based COVID-19 vaccines "permanently alter your DNA". These claims are really a concern about "impurifying" their "purity of essence" and have now gone into some truly disturbing territory, such as antivaxxers calling themselves "purebloods".
Ars Technica recently published a story about Hacker X, who helped Mike Adams expand his online empire of health fraud into an empire of fake news and political disinformation, thus intertwining health and political misinformation into the deadly combination we see now.
COVID-19 and antivaccine conspiracy theorists like Joe Mercola, Michael Yeadon, and Peter McCullough are spreading the conspiracy theory that COVID-19 vaccines are intended as a tool for "global depopulation". This is nothing more than an old antivaccine conspiracy theory repurposed for the pandemic. As ridiculous as it might seem, it is nonetheless very appealing to antivaxxers.
The latest antivaccine disinformation consists of pointing to the large numbers of reports of death (and other adverse events) to the VAERS database. It's nonsense.
Reports of enlarged lymph nodes under the arm after COVID-19 vaccination have led doctors to tweak mammography guidelines. Antivaxxers, unsurprisingly, have tried to weaponize this observation to spread fear and confusion about these vaccines.
The latest antivaccine propaganda claims that a 2018 research paper published by researchers at Memorial Sloan-Kettering Cancer Center shows that the RNA in the Moderna and Pfizer COVID-19 vaccines can cause cancer. As usual, it's a complete misapplication of a cherry picked study grounded in a lack of understanding of molecular biology. Same as it ever was.
