The study, which is yet to be peer reviewed, looked into the cases of 44 vaccinated and 22 non-vaccinated long COVID patients.
Before vaccination, most patients showed serious symptoms and complained of fatigue, breathlessness and insomnia.
In January and February, a few of the participants received their vaccine shot, following which their symptoms were matched to those who were yet to get vaccinated. A month later, both the groups were reassessed and were asked whether their symptoms had improved, worsened or stayed the same.
Researchers found a 5.6 per cent decrease in worsening symptoms and 23.2 per cent increase in symptom resolution among the vaccinated participants in opposition to 14.2 percent and 15.4 percent for the unvaccinated respectively.
However, the scientists clarify that the study is too small “to make firm conclusions.” According to them, more research needs to be conducted in support of the claim.
