The Corona mutant from India has now arrived in all 16 federal states.
Do the approved vaccines also work against the Delta variant?
50.1 percent of Germans have been vaccinated against the corona virus at least once (as of June 18, 2021). But the delta variant, which was first detected in India and classified as "worrying" by the World Health Organization (WHO), has meanwhile also spread in Germany. In Great Britain it is already the predominant variant. There she is now responsible for 96 percent of all new infections. In Germany too, it is expected that
variant B.1.617.2 could be the dominant one
by
autumn
at the latest
- immunologists warn against this. But do vaccinations from Biontech / Pfizer, AstraZeneca, Moderna and Johnson & Johnson also protect against the mutation?

The Indian mutant is more resistant to corona vaccines
Several laboratory tests show that the
Indian variant is more resistant to vaccines
than others.
A British study was published in
The Lancet in
early June
.
This shows that the number of antibodies after two vaccine doses from Pfizer / Biontech was six times lower in the Delta variant than in the original type of corona virus.
The so-called antibody titer was weakened by a factor of 2.6 against the British alpha variant and by a factor of 4.9 against the South African variant beta.
However, initial investigations under real conditions give cause for hope.

Complete vaccinations prevent severe courses - even with the delta variant
According to a study by the British health authority Public Health England (PHE), severe disease courses in the Delta variant can be avoided with a full corona vaccination. The vaccination for the alpha variant is just as effective. Two doses of the Pfizer / Biontech vaccine prevented inpatient treatment in the Indian variant in 96 percent of the cases. For the Astrazeneca vaccine, the rate was 92 percent. And a study published by the British health authorities comes to similar results.
Only a single dose provides only limited protection against the novel mutant.
For example, the French Pasteur Institute stated that a single dose of Astrazeneca had “little to no effectiveness” against the Delta variant.
This is also supported by data from the UK government.
They found that three weeks after the first vaccination, both vaccines were only 33 percent effective against a corona disease caused by variant B.1.617.2.
