“COVID-19 vaccines are going to sterilize our womenfolk,” Take 2
Antivaxxers have long claimed that vaccines, particularly HPV vaccines, can damage the ovaries and cause female infertility. That claim has been resurrected for COVID-19 vaccines. The first example relied on a dubious "similarity" between the SARS-CoV-2 spike protein and a placental protein. This time, it's the lipid nanoparticles attacking the ovaries, echoing very old claims about polysorbate-80. Truly, everything old is new...
The origin of SARS-CoV-2, revisited
Since early in the pandemic, scientists have overwhelmingly concluded that evidence points to a natural origin for SARS-CoV-2, the coronavirus that causes COVID-19, as a far more likely explanation for the pandemic than a laboratory origin. In May, however, there has been a lot of media chatter about the "lab leak" hypothesis, and President Biden even ordered US intelligence agencies to look...
The “deadly” coronavirus spike protein (according to antivaxxers)
Antivaxxers are citing three papers to support their claim that spike protein produced by COVID-19 vaccines is dangerous. Unsurprisingly and as usual, they're misinterpreting the studies and misrepresenting their significance. COVID-19 vaccines are, in fact, very safe.
Spike Proteins, COVID-19, and Vaccines
A new study further elucidates the role of spike proteins in COVID-19.
“The vaccinated are a danger to the unvaccinated because of shedding!”: The latest COVID-19 antivaccine disinformation
Antivaxxers are masters of projection, which is why the latest antivaccine disinformation about COVID-19 vaccines is that they lead the recipient to "shed" spike protein, which can can cause menstrual irregularities or even miscarriages in women who come into contact with the vaccinated and even make people very sick. This trope is nothing more than a clever repackaging of the old antivaccine...
Antivaxxers misrepresent a study to falsely claim that COVID-19 vaccines cause cancer
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.
Can mRNA-based COVID-19 vaccines cause prion disease or Alzheimer’s?
Antivax immunologist J. Bart Classen published a paper claiming that mRNA-based COVID-19 vaccines can cause prion disease leading to neurodegenerative diseases like Alzheimer's dementia. What are prions, and can these vaccines cause prion disease? (Spoiler alert: The answer to the second question is almost certainly no. It's speculation based on highly implausible biology.)
