COVID VACCINE: At the least efficient towards COVID LONG

Thus, 8 of the ten most ceaselessly reported signs within the lengthy types of the illness are, after 2 doses of the COVID-19 vaccine (right here mRNA vaccine BioNTech, Pfizer) reported between 50 and 80% much less usually, than in folks much less vaccinated.

At the least 2 doses of COVID vaccine considerably scale back the danger of lengthy COVID

The research analyzed knowledge from practically 3,500 contributors, on their historical past of an infection, their vaccination standing and their attainable signs associated to COVID-19.

  • greater than half of contributors reported no earlier SARS-CoV-2 an infection,
  • 951 declared an an infection of which 67% had acquired a minimum of 2 doses of vaccine;

  • the most typical signs together with fatigue, headache, weak point and protracted muscle ache are lowered by 62%, 50%, 62% and 66% respectively;
  • the symptom of shortness of breath is lowered by 80%.

The research informs us for the primary time about this protecting dimension of long-term COVID vaccination. Thus, vaccination, if it doesn’t “forestall” the an infection, reduces the danger of extreme varieties but additionally of lengthy types of the illness.

“As a result of the prevalence of long-term COVID seems to extend over time, it was necessary to check whether or not vaccines might assist mitigate its long-term, generally disabling results on independence and day-to-day functioning.”
