Do mRNA vaccines cause antiphospholipid syndrome?

The Claim:

The self-proclaimed inventor of the optical mouse once again captured your curiosity with a claim about blood clots and mRNA vaccines. According to this tech enthusiast, the vaccines induce antiphospholipid syndrome, a condition where your immune system gets confused and starts attacking the healthy proteins found in your blood.

The Facts:

One of your second favorite links this year is the Yale study at the end of our debunking. Read on!

Frightening anecdotes are always difficult to counter because we never have all the information we need from the medical records to form a complete opinion about the causes and features of a person’s health experience. We do know, from the linked article, that the doctors treating the child during his medical emergencies did not see vaccines as the cause of his blood clots or autoimmune issues. The family received a second opinion from a doctor in Florida who made a name for himself by treating COVID patients with Ivermectin, an ineffective treatment favored by agents of disinformation.

In one study of American veterans aged 45 and older, researchers discovered a slight increase in the risk of VTE (blood clots in the veins) following COVID vaccination with both viral vector and mRNA vaccines. This increase amounted to only 0.10%, or roughly 1.4 additional VTE cases per 1,000,000 vaccinated people, reaffirming the overall safety of these vaccines and the extremely low risk of blood clots.

We do know that COVID infection is far more likely to lead to autoimmune problems. New research from Yale indicates that COVID mRNA vaccines do not lead to the development of autoantibodies, which are self-attacking antibodies commonly found in COVID patients. This finding suggests that vaccination is associated with a substantially lower risk of autoimmune diseases compared to getting infected with the virus. The study highlights the benefits of vaccination in generating protective immunity without the risk of autoantibody development, making vaccination a safer choice for reducing the risk of autoimmune responses.
