You’ve heard of “long COVID,” the cases of people who can’t shake the lingering symptoms of COVID-19.
Now comes “long vax” — a rare, but baffling set of symptoms that follow a small number of people for months after receiving the COVID-19 vaccine.
“You see one or two patients and you wonder if it’s a coincidence,” Dr. Anne Louise Oaklander, a neurologist and researcher at Harvard Medical School, told Science.
“But by the time you’ve seen 10, 20 [patients],” she said, “where there’s smoke, there’s fire.”
Cases are very rare — even less common than the few reported cases of long COVID — and medical experts are still analyzing data to determine what might be behind them.
Symptoms of long vax can mimic those of long COVID: headaches, intense fatigue and abnormal heart rate and blood pressure.
