"Two trains are racing towards each other," warns SPD health expert Karl Lauterbach in a tweet.
The third wave has started and cannot be stopped.
In addition, the B.1.1.7 mutation will "become fully established" in Germany, he predicts.
On the other hand, everyone wanted to finally relax.
Lauterbach therefore calls for two measures to be combined.
On the one hand, an "immediate change in the vaccination strategy" is necessary.
The first vaccination of all vaccines must be brought forward, after all, this can prevent more than 80 percent of hospital admissions.
The vaccine from AstraZeneca should also be used for the elderly.
Lauterbach believes that the proposal by Bavaria's Prime Minister Markus Söder to offer the AstraZeneca vaccine to all those willing to be vaccinated is wrong.
With younger people it is less urgent, the risk lies with older people.
"If we use it for the elderly, no vaccine is left lying around and numerous deaths are prevented," says Lauterbach.
As for the easing, Lauterbach suggests that an antigen test be carried out once a week in factories and schools.
You are only allowed to go to shops on the day of the test - upon presentation of the certificate.
Those who cannot be tested in school or in the company should go to the test center.
As soon as enough antigen tests are available, testing can be expanded to twice a week - "then you can go to the shops on two days," says Lauterbach.
With this strategy, the R value drops to below 1, even for the B.1.1.7 mutant, he is convinced.
Saxony, Bavaria and Thuringia want to help the Czech Republic with a corona vaccine.
Saxony's government spokesman Ralph Schreiber said on Sunday the delivery of a total of 15,000 vaccine doses to the neighboring country is planned for Monday.
"MDR Aktuell" had previously reported on it.
The Czech government will therefore decide on the further distribution.
The Czech Republic currently has the highest infection rate in the entire EU.
The country with 10.7 million inhabitants has registered around 1.2 million infections since the beginning of the pandemic.
More than 20,000 corona patients died.
