Denmark became the first country to stop using AstraZeneca's vaccine on Wednesday.
The Danish health agency made their decision based on a potential link between AstraZeneca's COVID 19 vaccine and a rare but serious blood clot.
Astrazeneca said it respected Denmark's choice and would continue to provide it with data.
Meanwhile, this decision pushes Denmark's vaccination drive back to early August.
The new timeline assumesit will start using the Johnson and Johnson vaccine, but that isn't certain either as the J&J rollout in Europe has been delayed over similar clotting concerns.
In other parts of Europe countries have resumed using the AstraZeneca shot, with some restricting it to mostly those aged above 50 or above 60.
