Norway, where four people died after receiving their AstraZeneca shot and one in 20,000 developed serious side effects, is still investigating a broader connection. Several experts have since argued that it will be difficult to resume the use of AstraZeneca after a hiatus.
Frode Forland, the director of infection control at the Norwegian Institute of Public Health, described the events as "very serious", stressing that a thorough investigation is in store. Forland cited a recent study conducted by the University of Tromsø that indicated a likely link between vaccination and the serious side effects including an unusual form of coagulation disorder that led to blood clotting and low platelet count which can cause a haemorrhage. According to Frode Forland, the Tromsø study suggested antibodies to the platelets as a possible mechanism.
"We look at the individual cases, but also at the epidemiological level where the benefit to the population is weighed against possible side effects", Frode Forland emphasised in an interview with the Swedish daily Dagens Nyheter.
However, the recent alarm combined with delayed deliveries have increased scepticism about AstraZeneca's vaccine, both among ordinary Norwegians, whose willingness to vaccinate dropped by 11 percent in a recent poll, and the medical community.
The chairwoman of the Association for General Practice, Marte Kvittum Tangen, said it will be difficult to resume the use of Astra Zeneca's vaccine if you are looking for a high vaccination turnout. According to reports from Norwegian general practitioners, the willingness to vaccinate has declined significantly .
Vaccine researcher from the University of Oslo Gunnveig Grødeland plainly said that it is unlikely that AstraZeneca's vaccine will be used in Norway again, citing strong reasons to abstain."There is no report of general vaccine resistance, but people clearly say that they don't want the AstraZeneca vaccine. There is great uncertainty and scepticism", Marte Kvittum Tangen told national broadcaster NRK.
"Those who have experienced the side effects of the vaccine are not in a risk group for getting serious symptoms of COVID-19. This makes it even more important to find out what the cause is", she told TV2.
