According to a new study, the risk of what is known as long COVID drops almost in half after a person receives two doses of coronavirus vaccine.
The study, published Wednesday in the medical journal The Lancet, found that two doses of the vaccine cut the chances of having symptoms for 28 days or more after infection after vaccination.
The study also found that almost all symptoms were less common in vaccinated people, that more people in the vaccinated than the unvaccinated groups were completely asymptomatic, and that COVID-19 was less severe (both in terms of the number of symptoms in the first week infection and hospitalization) in participants after the first or second vaccination dose compared to unvaccinated participants.
The study was based on 1.2 million people who used a COVID symptoms app in the UK. The country used the vaccine jointly manufactured by Pfizer
