The suspension of a separate batch of Italy was tied to a person from Sicily who died from a bullet. It is not clear whether a blood clot was involved.
More than 142,000 people in Denmark, with a population of about six million, have been injected with the vaccine produced by AstraZeneca.
Denmark’s Minister of Health, Magnus Hunnicke Said on twitter It is that “it is not possible to conclude at present whether there is a connection.” she added. “We acted quickly, it should be thoroughly investigated.”
Denmark had already withdrawn the goal of ending its vaccination campaign due to delays in childbirth. The security stagnation will delay it further.
AstraZeneca’s vaccine came under scrutiny last year over potential safety issues, while it was tested in clinical trials. Two vaccination volunteers in the UK developed neurological symptoms with transverse myelitis, an inflammatory syndrome that affects the spinal cord and is often caused by viral infections.
Those concerns temporarily halted global vaccine trials, but the investigation eventually found no evidence linking the vaccine’s symptoms. One of the participants who fell ill was later found to have an unplanned case of multiple sclerosis.
More than 70 countries have authorized the vaccine, with the notable exception of the United States, where regulators await some large clinical trial data that are expected in the next few weeks. A decision by the Food and Drug Administration on whether to authorize the AstraZeneca vaccine is likely to exceed one month.
The most comprehensive real-world data on vaccine safety comes from the UK, which administered 9.7 million doses through the previous month. “The number and nature of suspected adverse reactions reported so far are not uncommon compared to other types of regular vaccines,” said the British drug regulator, Medicines and Healthcare Products Regulatory Agency.
