Exterior the physique, the virus does not final lengthy, making airborne droplet infections uncommon.

Is there a vaccine towards the Marburg virus?

Vaccines towards the Marburg virus haven’t but been authorized by regulators, however they exist already, Stephan Becker, director of the institute for virology on the College of Marburg, instructed DW.

“It is really not tough to develop vaccines towards Marburg virus, and there are already vaccines that work very properly in animal fashions. However the scientific research required for approval have to this point been missing,” Becker mentioned.

Not like with outbreaks similar to COVID-19, there’s a lack of political will and financial incentive to provide a vaccine, he added.

“It is precisely the identical state of affairs as with Ebola in 2013,” Becker mentioned. “We bought along with many others on the time and carried out Part I research comparatively rapidly, which then had been accomplished by Part II and Part III research in West Africa. The vaccine was actually superb and the pharmaceutical firm Merck then produced many a whole lot of 1000’s of doses for an outbreak of the Ebola virus within the Congo in 2018.”

This vaccine has since been authorized.

“There may be additionally a really comparable vaccine towards the Marburg virus that’s probably even higher than the one towards the Ebola virus,” Becker mentioned. “In monkeys, the vaccine was even efficient after an infection, so it really works as a sort of therapeutic vaccination.”

As soon as the required scientific trials have been accomplished and the required approval obtained, a vaccine might be produced rapidly, Becker mentioned.

Becker additionally mentioned medication recognized for his or her affiliation with COVID-19 might be used to deal with Marburg virus. One instance, he mentioned, might be remdesivir, which was initially developed to deal with Ebola.

 “The enzyme that replicates the RNA of the virus is comparatively comparable between the Marburg and Ebola viruses,” he mentioned.
