COVID-19 vaccine which was meant to protect people from the virus did not cause adverse effect to most people, but to some it the symptoms were chronic.
Scientists from Yale have however discovered why some people experience the chronic symptoms after receiving the jab in what they term post-vaccination syndrome (PVS).
In their findings the researchers found potential immunological patterns which was unique to people experiencing PVS and their hope is that they could find a treatment and therapies for them in the future.

“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
“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.” he continued
Some of the symptoms experienced by those with PVS include excessive fatigue, exercise intolerance, brain fog, insomnia and dizziness according to Yale researchers.
According to the researchers, those with chronic symptoms were found with low levels of two types of white blood cells and lower levels of antibodies against the SARS-CoV-2 spike protein.
“We don’t know if the level of spike protein is causing the chronic symptoms, because there were other participants with PVS who didn’t have any measurable spike protein — but it could be one mechanism underlying this syndrome,” said Iwasaki
Other factors discovered among those with PVS include autoimmunity, tissue damage and reactivation of Epstein-Barr virus (EBV).
