COVID – This is the effectiveness of vaccines against the delta variant

After one dose, Pfizer and AstraZeneca were vaccinated only approximately 10 percent are protected against the Indian delta variant of the coronavirus, according to a recent study published in the scientific journal Nature on Thursday. However, administration of the second dose increases protection to 95 percent.

According to the study, the delta variant is otherwise approx. twice as contagious as the first variant of the coronavirus detected in Wuhan, China, and 60 percent more contagious than the variant detected in Britain.

The delta is currently the predominant coronavirus variant in almost every country where the number of infected people is increasing, but the disease is now largely spread only among unvaccinated people.

In high-vaccination countries, therefore, another wave has not yet been accompanied by a surge in deaths and a strain on hospitals, in low-graft areas, however, these indicators have also jumped.

Incidentally, the study suggests that the delta variant is already able to avoid certain antibodies that target parts of the coronavirus, and therefore poses a serious threat.
