Swiss drugs regulator swissmedic on Wednesday said it saw no link between the death of a 91-year old person in the canton of Lucerne and the Covid-19 vaccine, adding the deceased suffered from multiple illnesses before getting the shot.
"Clarifications by cantonal health authorities and swissmedic determined that, as a result of the illness history and disease course, a link between the death and the Covid-19 vaccine was highly unlikely," the regulator said in a statement.
Swissmedic said previous illnesses would be listed on the death certificate as the person's "natural cause of death".
Lucerne was the site of the first vaccinations in Switzerland last week, with a shot from Pfizer and its German partner BioNTech given primarily to elderly people.
Switzerland has received 107 000 Pfizer/BioNTech doses so far, and expects to get 250 000 per month starting next year.
Pfizer and BioNTech's vaccine is the only inoculation approved so far in Switzerland. It was approved on an emergency basis in the United States and Britain, and has conditional marketing approval in the European Union after trials in tens of thousands of people.
