Wie effektiv sind Covid-19 Impfungen?

February 3, 2021 - Eine Einzeldosis der Coronavirus Vakzine von Oxford-AstraZeneca ist zu 76 Prozent für drei bis 12 Wochen nach der Injektion wirksam, das ergaben die Versuche. Die Wirksamkeit steigt auf 82,4 Prozent nach Verabreichung der zweiten Dosis nach 12 Wochen.

The results of the University of Oxford study, which has not yet been formally published, also suggest that the vaccine may have a “substantial” effect on transmission of the virus, the BBC said.

It means the jab could have a greater impact on the pandemic, as each person who is vaccinated will indirectly protect other people too.

The study found the Oxford-AstraZeneca vaccine offered 76% effective protection from a single dose for three months.

With no fall in protection during the three-month period, the researchers said the results supported gaps between first and second doses of between four and 12 weeks. The effectiveness of the vaccine increased with a longer gap of 12 weeks before the booster jab.

When the second dose is given, the study found the level of protection from the Oxford-AstraZeneca vaccine rises to 82%, the BBC said.
