Mpox vaccine maker Bavarian Nordic seeks ‘critical’ EU approval for adolescents after WHO declares health emergency

LONDON – Danish biotech company Bavarian Nordic said on Friday that it had submitted data to the European Union's medicines regulator to expand using its Mpox vaccine in adolescents.

CEO Paul Chaplin told CNBC that the expanded eligibility for 12- to 17-year-olds is critical to contain the outbreak of the most recent virus variant group 1b, which particularly affects teenagers and young children.

Earlier on Wednesday, the World Health Organization declared an escalating MPOX outbreak in Africa a public health emergency after the primary case of the brand new variant outside the continent was confirmed in Sweden on Thursday.

“The latest data we have presented is really, really important because it will hopefully help expand the use of our vaccine in adolescents as well,” Chaplin told Squawk Box Europe.

“More than 70 percent of cases in Africa currently affect people under 18, so it is crucial that our vaccine can also be used in this younger age group,” he said.

Bavarian Nordic's Jynneos vaccine, also often called Imvanex, is currently only approved to be used in adults ages 18 and older. It can also be the one mpox vaccine approved by the U.S. Food and Drug Administration and the European Medicines Agency.

Bavarian Nordic seeks approval of “critical” Mpox vaccine for adolescents, says CEO

If the EMA approves the vaccine for teenagers, the corporate says this might pave the best way for approval for teenagers in Africa. The company can also be currently studying the effectiveness of the vaccine in children aged 2 and over. The results are expected next 12 months.

Following the WHO's declaration of a state of emergency, Bavarian Nordic's share price rose 17 percent on Thursday, as did other stocks within the healthcare sector, as demand for the vaccine was expected to extend. By midday on Friday, the share price in Copenhagen was up one other 17.5 percent.

Chaplin said the corporate has significant stockpiles of the vaccine and it’s “ready to ship” to countries in need, but he pointed to shortages in Africa which have thus far prevented distribution.

The vaccine is currently only approved within the Democratic Republic of Congo – the epicenter of the outbreak – and Nigeria. Chaplin said the corporate continues to work with authorities in affected neighboring countries to enable access to the vaccine.

“There is now an approval in the Democratic Republic of Congo and also in Nigeria. That now opens the door, both for governments to buy the vaccine and for Bavarian Nordic, as we have done, to donate doses and have those doses shipped and hopefully we can start vaccinating people very, very soon,” he said.

So far this 12 months, greater than 15,000 cases and not less than 537 deaths have been reported from the outbreak, in line with to the WHOIt follows an earlier outbreak of a distinct strain of Mpox in 2022, which was also declared a public health emergency.

The European Centre for Disease Prevention and Control warned on Friday of a high risk of infection for travellers to affected countries, however the WHO said it was not recommending border closures at the moment.

Chaplin said authorities were now higher in a position to tackle the outbreak because vaccine doses were already available, particularly in wealthy countries that had built up large stockpiles through the last outbreak. But he urged greater international cooperation to make sure vaccine doses reached those that needed them most.

“Bavarian Nordic is part of the solution, but we are not the only solution,” he said. “The international community needs to work with Bavarian Nordic and really find a way to distribute this vaccine and contain the outbreak.”
