Covid-19: This is how well vaccinated people are protected

How well vaccinations work and what came out of vaccination priorities and vaccination privileges at the vaccination summit on Monday

According to the authorities and experts in Germany, all four Covid-19 vaccines previously approved in Europe are equally suitable for protecting individuals and containing the pandemic. It is believed that they prevent the majority of serious and potentially fatal disease courses.

Vaccinated people have a lower risk of developing Covid-19

Depending on the vaccine, vaccines are less likely to contract Covid-19 than those who have not been vaccinated - by up to 70 percent for the vector-based vaccine from Johnson & Johnson, up to 80 percent for Astrazeneca up to a maximum of 95 percent for both mRNA- Preparations from Biontech / Pfizer and Moderna.

This emerges from an overview by the Paul Ehrlich Institute (PEI). However, a direct comparison of these percentages says little: in clinical studies, the preparations were not compared with one another. With three of the four vaccines currently available, two doses are required for full protection.

Unclear how long the vaccination protection lasts

According to the recommendation of the Standing Vaccination Commission (Stiko), there should be six weeks for mRNA vaccines and twelve weeks for Astrazen. The protection does not appear immediately after the injection: According to the PEI, it is from day 7 after the second vaccination for the agent from Biontech / Pfizer, for Moderna from day 14 and for Astrazeneca from day 15.

After the single dose of Johnson & Johnson, protection exists from day 28. How long vaccinated people will be protected cannot yet be said. It is assumed that fully vaccinated people play a lesser role as carriers of the virus than unvaccinated people. The Stiko writes: It can be assumed that the virus excretion is greatly reduced in people who have become infected despite having been vaccinated twice.

To a limited extent, however, they seem to be able to pass on an infection. This is why vaccinated people are also recommended to continue to adhere to protective measures. According to a study, people benefit from the first dose of vaccine - regardless of whether they received Biontech / Pfizer or Astrazeneca.

Vaccines also protect against mutations

A large-scale study by Oxford University in cooperation with the British statistics agency ONS and the country's Ministry of Health recently showed that the risk of corona infection fell by 65 percent three weeks after vaccination, the university recently announced.

Regarding the role of virus variant B.1.1.7, which now dominates in Germany, the Stiko explained that all of the vaccines approved in Europe offer “very good protection against symptomatic disease”. The protective effect against symptomatic diseases by the mutant B.1.351 discovered in South Africa is "on the other hand significantly reduced"; According to data from the Robert Koch Institute (RKI), this variant has consistently made up a very low proportion in Germany.

According to Stiko, study data indicate a protective effect of all approved vaccines against severe courses - even if B.1.351 is present.

Soon vaccinations without prioritization

Corona vaccinations should be possible for everyone in Germany by June at the latest - i.e. without the previous prioritization with a fixed order. "That does not mean that everyone can be vaccinated immediately," said Chancellor Angela Merkel (CDU) on Monday in Berlin after consultations with the Prime Minister. "But then everyone can try to get a vaccination appointment and they will be given according to the supply."

Federal Minister of Health Jens Spahn (CDU) had also spoken out in favor of vaccination approval in June - after the third group was to come into play in May. In addition to those over 60, this includes supermarket salespeople, bus drivers, judicial officers and teachers in secondary schools. They couldn't work from home. The next step is the end of the prioritization in June, he said on the TV channel world. If more vaccine comes, “sooner, too”.

Berlin's Governing Mayor Michael Müller (SPD) emphasized that in addition to vaccination practices, the regional vaccination centers of the federal states would be needed for a long time. There are those who have already booked second appointments there. “But we will still have large population groups that we will want to vaccinate quickly, if you think of the younger ones, the students, the trainees.” At the same time, the company doctors should also be involved in the vaccinations as quickly as possible.

Bavaria's Prime Minister Markus Söder (CSU) called the Bund-Laender Round a Prime Minister's Conference (MPK) “of hope” and predicted: “We will overcome Corona. And we will take huge steps forward in the next few months. "

Criticism from the opposition

Merkel shared this assessment, but stressed that there were still many problems. The danger of overloading the health system has not been averted. "That's why weeks of exertion are still necessary."

The Left criticized: "The fact that there has been no signal to deal with vaccinated and convalescents is unacceptable," as parliamentary group leader Dietmar Bartsch told the newspapers Funke media group said. FDP boss Christian Lindner also missed a signal there for the involvement of specialist and company doctors in the vaccinations.
