Two panels show how PD-L1 on tumor cells binds to PD-1 on T cells to block immune response, and how anti-PD-L1 or anti-PD-1 drugs block this interaction, allowing T cells to kill tumor cells.

The opposite of “turbo cancer”: COVID-19 vaccines sensitize cancer to immunotherapy

A new preliminary study published in Nature suggests that COVID-19 vaccines might actually boost the immune system to make immunotherapy more effective. If confirmed in followup studies, this result suggests that the vaccines do the opposite of causing "turbo cancer."

Two prescription pill bottles labeled Eltroxin (100 mcg) and Synthroid (88 mcg), both containing levothyroxine tablets, are placed side by side on a gray surface.

What do mRNA vaccines, Synthroid, and pharmaceuticals have in common (according to MAHA)?

If you want to understand why Secretary of Health and Human Services Robert F. Kennedy Jr. has halted $500 million in funding for mRNA vaccine development, look no further than Synthroid and herbal medicines.

Two clear bottles with red caps, filled with raw cow milk, sit side by side on a countertop against a white tile backsplash. Each bottle is labeled “RAW COW MILK FOR CATS & DOGS.”.

Dr. Vinay Prasad: Bodily Autonomy Applies to Raw Milk, Not Vaccines

This is what it looks like when disinformation doctors pretend to value data and science to further their true objective, MAHA politics.

Turbo cancer?

COVID-19 vaccine-caused “turbo cancer” nonsense just keeps getting more turbocharged

No matter how implausible it is or how weak the evidence for it is, the myth that COVID vaccines cause "turbo cancer" just won't die. Quite the contrary, alas. Antivaxxers are—dare I say?—turbocharging it with bad science.

Frameshift mutation

Do mRNA vaccines produce harmful “junk proteins” that “gunk up” the cell and cause unintended “off-target” immune responses?

A new study is making the rounds in the antivax crankosphere. The study found that the modified mRNA used in the Pfizer vaccine can cause a frame shift (to be explained) that results in the production of proteins besides the intended spike protein. The findings are, as you probably guessed, a big nothingburger compared to how they are being spun.

Steve Kirsch: How “anti-COVID-19 vaccine” antivax often becomes radicalized and just plain antivaccine

Tech bro turned COVID-19 misinformation superspreader and antivaxxer Steve Kirsch has now fully embraced "old school" vaccine-autism conspiracy theories, demonstrating how anti-COVID-19 vaccine antivaxxers frequently become just antivaxxers.

Risk of Myocarditis Following COVID-19 Vaccine

Risk of myocarditis following mRNA vaccines is real but tiny, and far outweighed by the benefit of vaccines.

COVID-19 vaccines versus “purity of essence,” revisited

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".
