There seems to be an end in sight to the global pandemic ravaging countries across the world as Pfizer Inc. declared its latest findings from its Phase 3 trial of COVID-19 vaccine candidate, which has shown more than 90% efficacy in participants without prior evidence of SARS-CoV-2 infection.

Pfizer in conjunction with the German drugmaker BioNTech, announced their milestone discovery on Monday, following a first formal review of data by external panel of experts.

In a release obtained from Pfizer’s website, both pharmaceutical manufacturers revealed their intention to apply for emergency use of the vaccine by end of November, while they compile safety data as specified by the Food and Drug Administration, FDA.

The vaccine has been tested on 43,500 people in six countries and no safety concerns have been raised while it continuing to enroll and is expected to continue through the final analysis when a total of 164 confirmed COVID-19 cases have accrued.

With today’s news, we are a significant step closer to providing people around the world with a much-needed breakthrough to help bring an end to this global health crisis.
