Scientists find clues on why COVID vaccine causes chronic health problems in some

For a majority of people, the COVID vaccine doesn’t cause adverse health effects — but a small percentage experience chronic symptoms that can last for months or even years. Yale researchers recently made some discoveries about why certain people experience this condition, which they have dubbed “post-vaccination syndrome” (PVS).In early findings, the team recognized “potential immunological patterns” that are unique to people with PVS.The hope is that this discovery will help to enable future treatments and therapies for those who are affected.“This work is still in its early stages, and we need to validate these findings,” said co-senior study author Akiko Iwasaki, Sterling Professor of Immunobiology at Yale School of Medicine, in a press release.“But this is giving us some hope that there may be something that we can use for diagnosis and treatment of PVS down the road.”People with this condition may suffer from excessive fatigue, exercise intolerance, brain fog, insomnia and dizziness, according to the Yale researchers. These typically develop within a day or two of vaccination and can worsen over time.“It’s clear that some individuals are experiencing significant challenges after vaccination.

Our responsibility as scientists and clinicians is to listen to their experiences, rigorously investigate the underlying causes, and seek ways to help,” said co-senior author Harlan Krumholz, professor of cardiology at YSM, in the release.“Post-vaccination syndrome is real, and has been found [to occur] from many vaccines, including COVID,” Dr.Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, told Fox News Digital.The researchers analyzed blood samples from 42 study participants who experienced symptoms of PVS and 22 who did not.Those with symptoms were shown to have lower levels of two types of white blood cells.

People with PVS who had never had COVID also had lower levels of ant...
