All 13 patients were nursing home patients and were at least 80 years old. While officials do not express extreme concern, they are amending their guidelines on who should receive the vaccine.

„Doctors must now carefully study who should be vaccinated,“ he added. „Those who are extremely vulnerable and who at the end of life can be vaccinated after an individual assessment.“
