Only in a very few isolated cases do vaccinated people become so seriously ill with Covid-19 that they have to go to a clinic. This emerges from figures from the Berlin Senate, which are available to the Tagesspiegel: According to this, there were 13 patients in Berlin who, two weeks after a full vaccination – i.e. the second dose – were so difficult with one of the three previously common substances from Astrazeneca, Biontech and Moderna infected with Sars-Cov-2 that they were hospitalized.
Vaccinated persons are considered immune 14 days after the second dose. The counting date was June 4th of this year; two weeks earlier, more than 505,000 Berliners had been fully vaccinated. The current data comes from a response from Berlin’s State Secretary for Health Martin Matz (SPD) to the request of FDP MP Florian Kluckert.
Whether these 13 Covid-19 sufferers had to be treated in an intensive care unit, is unclear – “It is not possible to differentiate between normal inpatient treatment and intensive medical treatment cases,” writes Matz. The numbers say nothing about how many vaccinated people have contracted the coronavirus in total, because most courses are mild – after an immunization anyway. Doctors apparently rightly said that vaccination primarily protects against getting seriously ill with Covid-19.
How effective are Biontech, Astrazeneca & Co.?
Most Berliners have so far been vaccinated with the drug from Biontech, including the 13 people who still fell ill with Covid-19 had received this preparation. In its answer, the Senate also lists those cases of inpatient Covid 19 patients who had previously received a corona vaccination. Accordingly, after an injection with Moderna two, after Astrazeneca seven and after Biontech 48 Berliners had to go to a clinic because of Covid-19. On the reporting date, more than a million Berliners had been vaccinated for the first time.
This first dose is only partial protection for the vaccines mentioned. In the meantime, the vaccine from the US pharmaceutical manufacturer Johnson & Johnson, for which one dose is sufficient, is also used in Berlin. How effective the preparations used so far are for corona mutations is being debated. According to a recently published study, the vaccine from the German company Biontech also protects against the new virus variant Delta (B.1.617.2), which first appeared in India.
According to a British study, a full corona vaccination, i.e. consisting of two doses, can prevent severe disease progression even with the delta variant of the coronavirus. The vaccine also protects against other Sars-Cov-2 variants – such as the mutation B.1.525 that occurred in Nigeria, scientists from the University of Texas in Galveston write in the specialist journal “Nature”: The effectiveness of the antibodies was lower than in the variants in the case of a coronavirus type that was already isolated in January 2020, but it is still “robust”.
In Berlin, almost 50 percent of the population are currently vaccinated – and just under 25 percent fully vaccinated.
