The Czech Republic has declined an offer to buy AstraZeneca Plc’s coronavirus vaccines from an intermediary in the United Arab Emirates, Czech officials said on Wednesday.

Health Minister Jan Blatny said the offer was not officially from the UAE but that it came from an unnamed third party. “An offer arrived from this country from an intermediary,for a purchase from India,” he said on Twitter.

“It concerned a batch that does not have a permission for the European Union,” he said.

Prime Minister Andrej Babis later said he did not take the offer – or a similar proposition last month – seriously. AstraZeneca said there should be no private sector supply for sale or distribution of the vaccine in Europe.

“If someone offers private vaccines, it is likely counterfeit, so should be refused and reported to local health authorities, a company spokesperson said.

AstraZeneca has licensed the Serum Institute of India (SII),the world’s largest vaccine maker, to manufacture the shot mainly for poor and middle-income countries.

A spokesperson for SII was not immediately reachable for comment.

The number of infections, hospitalised patients and deaths in the Czech Republic, a country of 10.7 million, has spiked in recent days.

The country ranks among the worst-hit places in the world.

The government deployed more police officers and soldiers on Monday to help enforce new lockdown measures that seek to confine people mostly to their home districts.

Last month, Babis said in parliament that he and three other prime ministers in Europe had been offered AstraZeneca shots by a Dubai intermediary but he did not consider the offer to be reliable.
