OSLO 鈥 Danish biotechnology company Bavarian Nordic said on Monday the European Commission had given permission for its Imvanex vaccine to be marketed as protection against monkeypox, as recommended last week by the European Medicines Agency (EMA).

The approval comes just one day after the World Health Organization issued a high-level alert declaring the rapidly spreading monkeypox outbreak as a global health emergency.

鈥淭he availability of an approved vaccine can significantly improve nations鈥 readiness to fight emerging diseases, but only through investments and structured planning of the biological preparedness,鈥 Bavarian Chief Executive Paul Chaplin said.

Bavarian鈥檚 vaccine, the only one to have won approval for the prevention of monkeypox disease in the United States and Canada, has in the European Union (EU) so far only been approved to treat smallpox.

But the company has supplied the vaccine to several EU countries during the current monkeypox outbreak for what is known as 鈥渙ff-label鈥 use.

The approval is valid in all European Union Member States as well as in Iceland, Liechtenstein, and Norway, Bavarian Nordic said in a statement.

The development of Imvanex was made possible through significant investments from the US government during the past two decades, the company added.

Bavarian鈥檚 share price has risen by 122% in the last three months, driven by strong demand for the monkeypox vaccine. 鈥 Reuters
