Belgian health authorities announced they have inspected a pharmaceutical factory in Belgium to find out whether expected delays in the deliveries of AstraZeneca’s coronavirus vaccine are due to production issues.

The European Commission had asked the Belgian government to inspect the factory amid a heated public dispute between the 27-nation bloc and the Anglo-Swedish drugmaker.

EU officials are under tremendous political pressures because the bloc’s vaccine rollout has been much slower than that of Israel or Britain.

Chemical manufacturer Novasep’s factory in the town of Seneffe is part of the European production chain for the Oxford-AstraZeneca coronavirus vaccine.

AstraZeneca said last week that it planned to cut initial deliveries in the EU from the scheduled 80 million doses scheduled to 31 million doses because of reduced yields from its manufacturing plants in Europe.

The EU said it would receive even fewer, just one-quarter of the doses that its member nations were supposed to get during January, February and March.

However, the bloc’s executive commission said it remains confident that the AstraZeneca delay will not affect its plans to ensure that at least 80% of EU citizens over age 80 are vaccinated by March.

Stefan de Keersmaecker, the commission’s health policy spokesman, said that target is based on the availability of doses manufactured by Pfizer-BioNTech and Moderna.

“It is an ambitious target, but we believe it is a realistic one,” he said.

The EU, which has 450 million people, has signed deals for six different vaccines, but so far regulators have only authorized the use of two – one made by Pfizer and another by Moderna. T

The European Medicines Agency is scheduled to consider the AstraZeneca vaccine on Friday.

In total, the EU has ordered up to 400 million doses of the AstraZeneca vaccine and sealed deals with other companies for more than two billion shots.

A third round of talks between AstraZeneca and EU officials did not produce immediate results on Wednesday, but the commission still hopes the dispute can be resolved.

“What we have been discussing with AstraZeneca is how they can deliver to us as quickly as possible the doses which we believe are required in order to vaccinate the population,” European Commission spokesperson Eric Mamer said.

“We believe it is in the interest of European citizens.”

More than 400,000 EU residents with Covid-19 have died since the beginning of the pandemic.

According to the EU, the Belgian factory is one of four AstraZeneca sites included in the contract sealed by the commission and the company to produce vaccines for the EU market.

France Dammel, a spokesperson for Belgium’s health minister, said experts from the federal medicine agency inspected the Novasep site. They will now work with Dutch, Italian and Spanish experts before delivering a report in the coming days.

“Manufacturing the Covid-19 vaccine is a pioneering process in terms of scale, complexity and quantity,” Novasep said in a statement to The Associated Press.

“We have worked closely with AstraZeneca and conducted regular and coordinated reviews of the production processes to ensure the active drug substance was delivered on time and met the highest standards for quality and stability.”

Stella Kyriakides, the European Commissioner for health and food safety, said AstraZeneca should provide vaccines from its UK facilities if it is unable to meet commitments from factories in the EU. She also made clear the EU would find out if some of the doses manufactured in the EU were diverted elsewhere.

“No company should be under any illusion that we don’t have the means to understand what is happening,” Ms Kyriakides said. “We do have a knowledge of the production of the doses, where they were produced, and if they have bee sent anywhere, where this is.”

Meanwhile, Germany’s health minister said there are at least “10 hard weeks” ahead amid difficulties in getting large quantities of vaccines.

Health Minister Jens Spahn, who faces political pressure over the slow start to Germany’s vaccination campaign, wrote on Twitter that Chancellor Angela Merkel and the country’s 16 state governors should hold a special meeting to discuss vaccine strategy.

Mr Spahn said vaccine manufacturers also should be invited to “explain how complex production is”. He stressed that “the quality must be very good” in order to protect people.

Mr Spahn wrote that “we will go through at least another 10 hard weeks with the scarcity of vaccine”.

Germany’s current lockdown, its second, was extended until February 14.

Some 1.67 million people in Germany have received the first dose of the vaccine.

New infections are falling, but officials are worried about the impact of coronavirus variants such as the one first detected in Britain.

Germany’s interior minister said the country is planning to implement a ban on travel from so-called “mutation areas”.

Horst Seehofer told reporters on Thursday that the government hoped to decide by Friday on restrictions on travel from Portugal, Britain, South Africa, Brazil and possibly other areas in the coming weeks.

He suggested there could be exceptions made for the flow of goods, but said exceptions for things such as tourism were out of the question.

The country’s disease control centre, the Robert Koch Institute, would determine which countries should be determined “mutation areas”, Mr Seehofer said.

He refused to speculate on how long the restrictions could be kept in place.
