Thailand’s Princess Bajrakitiyabha, the eldest of the king’s children and a potential heir to the throne, collapsed on Dec. 14 while training her dogs for a competition. On Jan. 7, a palace statement said the 44-year-old princess fell into a coma due to a severe arrhythmia, or irregular heartbeat, caused by heart inflammation following a mycoplasma infection.
Mycoplasma is a kind of bacteria that typically affects the lungs, skin or urinary tract, depending on the species responsible for an infection. Most infections are mild, but some can be severe and even fatal. Mycoplasma pneumoniae, for instance, is a common cause of pneumonia, but in rare cases it can spread to other parts of the body, including the heart. Because these bacteria have no cell walls, like most bacteria do, some antibiotics won’t work against them.
The Royal Household Bureau has released three statements about Princess Bajrakitiyabha since her collapse. In the most recent one, from more than a month ago, authorities said the princess remained unconscious and that she was receiving antibiotics and heart, lung, and kidney support.
Despite no mention of COVID-19 vaccination, online articles and social media posts have baselessly claimed that the princess’s condition was caused by a COVID-19 vaccine and that Thai officials were banning Pfizer’s shots.
“Thailand to BAN Pfizer After Thai Princess Falls Into a Coma Following Booster Jab,” reads one Feb. 5 headline from a dubious website.
The claims stem from an interview, widely shared online by anti-vaccine activists, with a retired Thai-German microbiologist named Sucharit Bhakdi. Bhakdi, who has spread misinformation about COVID-19 and the vaccines before, claimed without evidence that the princess collapsed 23 days after a booster. He also said, incorrectly, that a bacterial infection “would never do what she’s suffering from,” and called the diagnosis “so ridiculous.”
Half an hour into the interview, Bhakdi said the vaccine was “deadly” and suggested that Thailand was going to cancel its vaccine contract with Pfizer/BioNTech.
