It is the second time this year that the British-Swedish company has delivered less than promised.

The EU and AstraZeneca had agreed that the company would deliver 180 million vaccines, but now there would be only 90 million.

What that means for the Netherlands is not clear.

The expected shortage would be due to a lack of raw materials in the first quarter.

"We are working very hard to increase our European production and so hope that we will be able to bring our deliveries back into line with the agreements," said an AstraZeneca spokesperson, who declined to comment on the news.

It is the second time that AstraZeneca is supplying fewer vaccines to the EU.

In January, the company warned Brussels that it could not meet its delivery goals.

If all goes according to expectations, AstraZeneca will have delivered 130 million doses to the EU by June, far less than the 300 million planned.
