Scientists at Yale and Harvard say they are starting to pay attention to conditions that may be caused by COVID-19 vaccines, which has been dubbed “long vax” in media outlets this week.
They said that symptoms of the so-called long vax, a term that was spawned from “long COVID,” can mimic those of long COVID, including fatigue, headaches, abnormal heart rate, and blood pressure issues.
Patients also describe electric shock-like sensations, burning pain, tingling, and blood circulation issues that come hours, days, and weeks after getting the COVID-19 shot, the article said. Some patients also have symptoms like postural orthostatic tachycardia syndrome (POTS), such as swings in heart rate and blood pressure, fatigue, mental clarity problems, and weakness.
“It’s my obligation, if I truly am a scientist, to have an open mind and learn if there’s something that can be done,” Dr. Harlan Krumholz, a cardiologist at Yale University who is conducting research into the phenomenon. “I’m persuaded that there’s something going on” with the side effects, the doctor told Science, which described long vax as “rare.”
Illness after vaccinations are “a long, relentless disease,” Lawrence Purpura, an infectious disease specialist at Columbia University, told Science, saying that he treats both long COVID and vaccination-related symptoms.
“LISTEN researchers will analyze the data for insights about the health of people in the study, including those with long COVID and those with syndromes after vaccination,” it says. “We will characterize demographic, clinical, social, and environmental factors associated with health status. We will share some results back with participants when analysis is completed. We will also treat participants with respect, listen to their suggestions about the study, and engage them in interpreting and disseminating results.”

Dr. Peter Marks, director of the Food and Drug Administration’s vaccine division, told the outlet that the agency “can’t rule out rare cases” of POTS after COVID-19 vaccinations. And individual doctors and medical professionals “may want to take seriously the concept [of] a vaccine side effect” that lasts longer than a few days, he said.“Two vaccines have been released since the last report. Since release, the number of incoming COVID-19 reports has significantly exceeded the estimated maximum of 1,000 reports per day,” General Dynamics Information Technology (GDIT) told U.S. Centers for Disease Control and Prevention in a status report published on Jan. 15, 2021. “As a result, GDIT is unable to meet processing and other timeframes (data processing, telephone inquiries, clinical [inquiries], etc.).”
“When I was told I had an irregular heartbeat, I asked the doctor if it could be related to the shot and if it could be myocarditis. He was hesitant to connect it to the vaccine,” Mr. Paquette, who was 33 at the time, said.
The Epoch Times contacted the FDA for comment about the claims on Friday.
