Denmark has stopped using AstraZeneca’s COVID-19 vaccine because of potential serious side effects.

The country has halted use of the vaccine for at least 14 days after several cases of blood clots among vaccinated people, the Danish health authority said Thursday. One of these cases was related to a death in Denmark, it said.

Magnus Heunicke, the Danish health minister, said that it wasn’t yet clear whether the clots were linked to the vaccine.

In a statement, the Danish health ministry said that there was good evidence that the vaccine, developed by AstraZeneca and the University of Oxford, was both safe and effective, but that it must react to reports of serious side effects.

A further six European countries have halted the use of a vaccine batch from AstraZeneca, the Danish authorities said.

Austria has stopped using a batch of AstraZeneca shots while investigating a death from coagulation disorders and an illness from a pulmonary embolism.

The Danish Medicines Agency said it has launched an investigation into the vaccine.

The investigation is being carried out by corresponding agencies in other EU-countries as well as the European Medicines Agency (EMA).

The EMA is in charge of the evaluation and supervision of medicinal products in the EU bloc.

Reacting to the reports, AstraZeneca maintains its vaccine is safe to use.

AstraZeneca said its shots are subject to strict and rigorous quality controls.

It said there have been “no confirmed serious adverse events associated with the vaccine.”

Kenya last week received the first batch of Astra Zeneca Vaccine, a milestone promise for a better tomorrow following an otherwise difficult year in dealing with the ravages of the COVID-19 pandemic.

The 1.02 million doses of the Astra Zeneca-Oxford COVID-19 vaccine, arrived at Jomo Kenyatta International Airport, Nairobi, on Wednesday March 3, 2021 as part of the COVAX facility.
