This increases the protection rate against the course of a disease with the need to go to an emergency room or immediate medical intervention to 87 percent. This is the result of a new US study from California.
Sara Tarof and her co-authors from Kaiser Permanente Health Insurance in California analyzed data from 3,168 adolescents regarding immunization coverage after two or three doses of Covid-19. The frequency of use of emergency departments or acute medical care caused by Covid-19 between November 1, 2021 and March 18, 2022 served as a benchmark. The mean age of the test persons was 15 years. The vaccine used was the Pfizer/BioNTech mRNA vaccine.
The results
Two doses of vaccinations resulted in 89 percent fewer cases of acute medical needs due to Covid-19 following infection with the delta variant of SARS-CoV-2 within the first two months after immunization. At Omikron, the protection rate was 73 percent. Up to six months after the second partial vaccination, the protective effect for infections with the delta variant was reduced to 49 percent and only 16 percent against the omicron variant.
As the authors finally found in the study published online in the network of the American Medical Society with the information from the US health insurance company, which is known worldwide in epidemiological circles, the third partial vaccination brings decisive advantages.
“A third dose of BNT162b2 (Pfizer/BioNTech mRNA vaccine; note) was associated with improved protection against omicron compared to two partial vaccinations. This underlines the importance of the ‘booster’ (third partial vaccination in Austria; note) for Adolescents between the ages of twelve and 17,” the experts wrote. This was already the case for the first month after the third partial vaccination, in which the protection rate was 87 percent.
Basically, this also corresponds to the Austrian recommendations for all people: “The third vaccination completes the so-called basic immunization. It is necessary for the best possible vaccination protection – including protection against severe courses. For people with a healthy immune system, a third vaccination is recommended from the age of five Recommended from six months after the second vaccination.”
