In the midst of the summer corona wave in Austria and other countries, studies published in the US show the very positive effect of the vaccination: The number of cases of Lung Covid has been reduced, a booster showed a good protective effect against infections in the US top basketball teams Covid-19 , thus the scope of three studies.
The vaccines have so far prevented about 60 percent of threatened pandemic deaths, according to studies in the US. The three publications can be found in the Journal of the American Medical Association (JAMA), one of the most respected medical publications.
Between March 2020 and April 2022, workers were observed in nine Italian health facilities. PCR tests were performed regularly. A total of 2560 people took part in the study. 739 (29 percent) developed the Covid-19 disease. After that, 31 percent showed signs of Long Covid. The share was 48.1 percent in the first Covid-19 wave, only to fall to 16.5 percent in the third wave at the end of the observation period.
Every vaccine dose worked
The studies also show that every vaccine dose makes a difference: 48.1 percent of those unvaccinated with Covid-19 developed Lung Covid, 30 percent got the disease after one dose of vaccine, 17.4 percent after two vaccine doses and finally 16 percent after three partial vaccinations and the disease still occurred.
A second study also looked at a special group of people — American professional basketball players. They had to have been vaccinated at least twice by October 1, 2021 and received the third partial vaccination against Covid-19 by January 5, 2022. The participants in the study were on average 33.7 years old, healthy, but – basketball as a team sport – a lot of indoor training and playing together. In the end, 85 percent had finally received the third partial vaccination.
Booster clearly leads to fewer infections
The effect according to the authors: The third partial vaccination against the pathogen SARS-CoV-2 reduced the risk of contracting Covid-19 by 57 percent. Symptomatic infections were even 61 percent rarer. “This study showed that in young, healthy and well-vaccinated groups of people with frequent check-ups for SARS-CoV-2, a booster vaccination (third partial vaccination; note) resulted in significantly fewer infections.”
A third scientific study estimating the number of Covid-19 infections, hospitalizations due to the disease and deaths from serious illness, by Molly Steele, is based on massive data sets for the entire US for the period from December 1, 2020 to September 30, 2021 by the US National Centers for Disease Control (CDC/Atlanta) and their co-authors. Before the possibility of vaccination against SARS-CoV-2 in the US, there were 16 million cases of Covid-19 and 310,000 deaths between January 19, 2020 and December 12 of the same year.
235,000 American deaths avoided
Taking into account the vaccinations that started in the US on December 12, 2020, the model calculation led to the following results for the period from the beginning of December 2020 to the end of September 2021: “The Covid-19 vaccination has an estimated 27 million infections with SARS. CoV-2 prevention, plus some 1.6 million hospitalizations and 235,000 deaths.The relative effectiveness of the Covid-19 vaccination was finally calculated for September 2021: 52 percent fewer infections, 56 percent fewer hospitalizations and 58 percent fewer deaths than it would have been without the corona vaccines.
