Pfizer Inc. stated that early efficacy tests of its coronavirus vaccine show that it's 90 percent effective.

On Monday the CEO Albert Bourla said that the pharmaceutical company and its collaborator BioNTech found in a phase 3 study that the potential COVID-19 vaccine was "found to be more than 90 percent effective in preventing COVID-19 in participants without evidence of prior SARS-CoV-2 infection in the first interim efficacy analysis."

"The results demonstrate that our mRNA-based vaccine can help prevent COVID-19 in the majority of people who receive it," said Bourla. "This means we are one step closer to potentially providing people around the world with a much-needed breakthrough to help bring an end to this global pandemic," Bourla said.

"This is a first but critical step as we continue our work to deliver a safe and effective vaccine," he added.

Bourla went on to say that more data is needed before the company can apply for FDA Emergency Use Authorization, and clinical studies are still ongoing.

"We look forward to sharing additional updates in the coming weeks and will continue to work closely with regulatory authorities to provide access to our anticipated vaccine for those who need it most," added Bourla.
