The London School of Hygiene and Tropical Medicine study warned more than 280,000 people could end up in hospital in Germany. This come as Europe is facing a new wave of the deadly virus.
The authors warned death and hospitalisations could rapidly rise in Covid restrictions are not tightened further.
Sheryl Chand, an infectious-disease modeller from the University of Sydney, said: “The numbers are shocking and they may or may not happen, but people need to be aware that COVID-19 isn’t over.”
According to new figures, Europe as a whole accounted for more than half of the seven-day average of infections globally and at least half of the latest Covid deaths.
Researchers collected data on Covid deaths across a range of age groups in 19 European countries.
They then estimated the total number of people who had been infected in each nation by early November 2021.
This figure was used to calculate the share of people who do not have Covid immunity because they either have not had both jabs or have not tested positive by the virus.
The researchers stressed this was a “worst-case scenario” that looked at what would happen if governments across Europe relaxed all Covid restrictions.
The study – which was published on MedRxiv and is yet to be peer-reviewed – also took into account people at risk despite having already been exposed to Covid.
