Amid the summer Covid 19 wave in Austria and neighboring countries, studies published in the U.S. show the very positive effect of vaccination: the rate of long Covid cases is reduced, and a booster showed good protective effects against infection in top U.S. basketball players and their teams. So far, according to the studies, vaccines have prevented about 60 percent of impending pandemic deaths in the United States.
The three publications are in the Journal of the American Medical Association (JAMA), one of the most respected medical publications. Elena Azzolini of the IRCCS Humanitas Research Hospital in Milan and her Italian co-authors recently published a scientific study on the effect of Covid-19 vaccination on the incidence of long-term health problems (Long Covid) after illness (doi:10.1001/jama.2022.11691).
Workers in nine Italian healthcare facilities followed between March 2020 and April 2022. Regular PCR testing was performed. A total of 2,560 people participated in the study. 739 (29 percent) developed a covid-19 disease. Subsequently, 31 percent showed signs of long covid. The proportion was 48.1 percent in the first Covid-19 wave, eventually dropping to 16.5 percent by the third wave at the end of the observation period.
