When the University of Oxford asked the Netherlands for a ten-million euro investment at the Halix vaccine plant in Leiden, it opened the door for the country, and likely the entire European Union, to gain access to millions more Covid-19 vaccine doses compared to what AstraZeneca delivered to the EU in the first quarter of 2021. The
university's scientists were days away from securing the backing of the pharmaceutical firm for its AZD 1222 vaccine
in late April when they approached the Netherlands with the request, anonymous sources told
broadcaster NOS.
The Halix facility was already under contract to produce the Oxford vaccine even as clinical trials intensified. "There will probably be a huge demand for vaccines if they successfully pass the tests. Most likely, the quantities of available vaccines will be limited for several months," a letter from the university, received by Prime Minister Mark Rutte, stated. "To avoid major delays, production capacity must be increased now."

The broadcaster viewed key elements of the letter, which said that the investment would be used to reduce bottlenecks at the Halix facility. By that point, t
he British government had already committed to a 25-million euro investment at the Halix plant in Leiden, making it possible to produce 200-liter barrels of a vaccine.

The University of Oxford asked the Netherlands to invest in boosting production capacity at the Halix pharmaceuticals plant in Leiden in April last year, broadcaster NOS said on Tuesday. But although there were some preliminary talks, the deal disappeared from the negotiating table after AstraZeneca signed its deal with Oxford, NOS said. The broadcaster bases its claims on ‘background talks’ and a letter to prime minister Mark Rutte. It says that
Oxford asked the Dutch government to invest €10m in Halix, around the same time as the British government put in €25m.
So, by Apr 20, the UK had invested 25M Euro into the plant and had a contract in place.
