 Study: Vaccination reduces long-term symptoms of COVID-19

At least two doses of Pfizer's COVID-19 vaccine significantly reduced most of the long-term symptoms people experienced months after contracting the coronavirus, according to a new study from the University of Bar- Ilan.

“It is becoming increasingly clear that vaccines protect not just against disease, but against the long-term, sometimes life-threatening consequences of COVID-19,” said Professor Michael Edelstein.

In this study, 8 out of 10 most Common symptoms were 50% to 80% less common in those who received at least two doses of the COVID-19 vaccine compared to those who did not.

The study, which was conducted from July to November 2021, involved nearly 3,500 Israeli adults. They each filled out a questionnaire in one of the four common local languages ​​- Hebrew, Arabic, English and Russian – with various questions about previous COVID-19 infection, vaccination status, and any symptoms they experienced.

More half of the participants (2,447) reported never having had COVID-19, while 951 people said they had been infected. Of those who became infected, 637 (67%) received at least two doses of the vaccine. Of the 2,447 people reporting no infection, 21 (0.9%) received one dose, 1,195 (48.8%) received two doses, 744 (30.4%) received three doses, and the remainder were not vaccinated (19.9%).

Researchers compared vaccinated and unvaccinated people in terms of acute symptoms they self-reported after exposure. After adjusting for factors such as age and time elapsed from exposure to survey response, they found that vaccination with two or more doses of the Pfizer vaccine reduced the risk of common symptoms following exposure.
