Moderna will increase its deliveries to 1.33 million doses a week in July from 733,000 previously expected, raising the figure to 2.57 million a week in August and 2.95 million a week in September, the ministry said.
Moderna said last week it hopes to be able to deliver the COVID-19 vaccines it has promised to Germany more quickly than originally planned, without giving figures.
Health Minister Jens Spahn said on Saturday that supply of vaccines in Germany will soon outstrip demand, which will allow it to offer shots to passers-by in city centres or at places of worship.
The government will deliver an additional 5 million doses of AstraZeneca vaccine and 1 million from Johnson & Johnson to the regions next week, the ministry said.
