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.
