Earlier, Norwegian officials said that 23 people had died in the country, shortly after receiving their first dose of the vaccine, and most of them were over eighty years old.
Of these deaths, 13 bodies have been autopsied so far, and the results indicated that common side effects may have contributed to severe reactions in the elderly, according to the Norwegian Medicines Agency.
According to official statistics, more than 30,000 people received the first dose of Pfizer Bionic vaccine Or “Moderna” in Norway, since the end of last December.
The Norwegian Institute of Public Health said: “For those who are very debilitated, even relatively mild side effects of the vaccine can have severe consequences. (For them) the benefit of the vaccine may be marginal or irrelevant.”
“The authority recorded fever and nausea as side effects. It may have resulted in deaths among some weak patients,” said Sighard Hurtemo of the Norwegian Drug Authority, in the first report on side effects.
However, the authority’s medical director, Steiner Madsen, said: “We are not worried about this. It is quite clear that these vaccines have a very low risk, with the exception of a small number in the case of weaker patients.”
He continued: “Doctors now have to be careful about who should receive the vaccine. The weakest and the oldest must undergo individual evaluation.”
The new head of the European Medicines Agency, Emer Koc, had said earlier that tracking the safety of Corona vaccines, especially those that rely on new technologies such as “mRNA”, will be one of the biggest challenges once they are widely distributed.
Allergic reactions after receiving anti-Corona vaccines are not yet common.
And in United StateFrom December 14 to December 23, the authorities reported 21 cases of severe allergic reactions after administering about 1.9 million initial doses of the “Pfizer Bionic” vaccine, at a rate of 11.1 cases per million doses, according to the Centers for Disease Control and Prevention.
Although the two “Covid 19” vaccines approved so far in Europe, “Pfizer Bionic” and “Moderna”, have been tested on tens of thousands of people, including volunteers in the late eighties and nineties, the average participants in the trials were in Early fifties.
And the first people to be vaccinated in many places were older than that, as countries scrambled to vaccinate nursing home residents at risk of contracting the virus.
Norway gave at least one dose to about 33,000 people, with a focus on those considered most at risk if they contract the virus, including the elderly.
