A leader of Germany's Greens, set to be part of a new government, has expressed support for mandatory vaccinations as the number of infections jumped again.

Germany registered 66,884 new coronavirus infections and 335 more deaths due to the virus, bringing the total number of deaths close to 100,000, according to figures by the Robert-Koch-Institute of infectious diseases on Wednesday.

Katrin Goering-Eckardt, the parliamentary leader of the Greens, said continual lockdowns and restrictions on social contact were a bigger imposition than demanding vaccination.

Initially, mandatory vaccinations were needed in care facilities to protect particularly sensitive groups, she told Deutschlandfunk radio. Introducing compulsory vaccination would not mean that this would be enforced by police, she added.
