Many people in Germany have already received two corona vaccinations. However, virologists and doctors are now assuming that the previous protection will not be sufficient.
Munich – There is more and more talk of a third vaccination when it comes to combating the corona pandemic. Experts assume that this will be absolutely necessary in order to get the coronavirus and its mutations under control. Because: research results one Israeli study show that immunity will not last long after the first vaccinations.
According to the study, immunity should last six to twelve months after vaccination against the coronavirus. This means that the first people could receive a third vaccination this year. How long this booster vaccination will last is still unclear. Prof. Dr. Dr. Franz-Xaver Reichl from LMU Munich is in the video interview Merkur.de (see above) but assume that the vaccination protection will not last longer than a year even after the third vaccination. The booster vaccination should initially be distributed primarily to risk groups, according to the expert.
Booster vaccination in the fight against the coronavirus: every year like influenza vaccination?
“In the end, it will probably come down to the fact that a booster vaccination should take place every year, similar to an influenza”, suspects toxicologist and microbiologist Reichl. Data on the third vaccination are not yet available. The pharmaceutical companies Biontech and Pfizer are currently in the process of testing the booster vaccination with volunteers, says Reichl.
The main thing about the booster vaccination is that it should work against the mutations of the coronavirus. At the moment, when fully vaccinated, all vaccines are more than 90 percent effective against the virus variants, as Reichl explains. The first vaccines, such as Biontech / Pfizer, are already being adapted to the Delta variant. And Reichl gives hope: The development of the vaccines only takes one to two months and is progressing relatively quickly. Thus, the vaccines could be adapted annually to possible mutants.
Which vaccine can be vaccinated with is subject to the vaccination-free, explains Reichl. This means that each person can choose which vaccine they would like to be vaccinated with. Cross-vaccinations with AstraZeneca and Biontech / Pfizer, for example, can even produce a higher level of vaccination protection. But: The vaccination intervals should be strictly adhered to, according to the expert.
Corona pandemic: Expert looks to the future
“If the situation remains as it is now, herd immunity of 90 to 95 percent could be achieved with the Delta variant,” says the Munich microbiologist in an interview. However, this only applies as long as no new virus variants appear. However, in the next one and a half to two years, every unvaccinated person would be one hundred percent infected with the corona virus, says Reichl.
The microbiologist also considers it likely that there will also be a general vaccination recommendation in the future STIKO for children and adolescents from the age of 12: “The permanent vaccination commission in Germany is still a bit cautious, but not against it”. For Reichl, it is important that children under the age of 12 also have the opportunity to be vaccinated. This age group often has milder courses, but often long-covid consequences.
