EU: Possible virus drug approval 'before the summer'

The European Medicines Agency predicted that there could be licensed drugs to treat the new coronavirus in the next few months and that a vaccine might even be approved in early 2021, in a “best-case scenario.”

Although it typically takes years to develop a vaccine, Cavaleri said that if some of the shots already being tested prove to be effective, they could be licensed as early as the beginning of next year.

“But we can see the possibility that if everything goes as planned, vaccines could be approved a year from now,” he said.

At the moment, there are about a dozen vaccine candidates being tested in China, Britain, Germany and the U.S. The World Health Organization has estimated it could take about 12 to 18 months for an effective vaccine to be found.

While some experts have proposed dropping the requirement for large-scale advanced clinical trials altogether, Cavaleri said that wasn't currently being considered.

“Our current thinking is all vaccines under development should undergo large phase 3 trials to establish what is the level of protection,” he said.

But he acknowledged that could change if the situation worsened.

“Things may evolve as the pandemic will evolve and we will see if we need to do something else,” Cavaleri said.

Some officials have warned that a vaccine might never be found; previous attempts to develop a vaccine against related coronaviruses like SARS and MERS have all failed. But Cavleri was optimistic an immunization against COVID-19 would eventually be discovered, as there are various technologies being tried globally.

“I think it's a bit early to say, but we have good reason to be sufficiently optimistic that at the end of the day, some vaccines will make it,” he said.
