ANKARA, Nov 10 — US drugmaker Pfizer and German biotech firm BioNTech announced Monday their COVID-19 vaccine candidate is more than 90 per cent effective against the novel coronavirus, Anadolu Agency reported.

The pharmaceutical firms said in a statement their vaccine candidate “has demonstrated evidence of efficacy against COVID-19 in participants without prior evidence of SARS-CoV-2 infection.”

The study had 43,538 participants, with 42 per cent from diverse backgrounds, and analysed 94 confirmed COVID-19 infections, with no serious safety concerns observed.

The companies said they will submit the vaccine candidate to the US Food and Drug Administration for emergency use authorisation, expected to occur in the third week of this month. 

“The case split between vaccinated individuals and those who received the placebo indicates a vaccine efficacy rate above 90 per cent, at seven days after the second dose,” the statement noted.

“This means that protection is achieved 28 days after the initiation of the vaccination, which consists of a two-dose schedule,” it added. 

There are currently more than 170 vaccine candidates for COVID-19 around the world tracked by the World Health Organization, while none has been approved yet for general use.

Globally, there are nearly 50.5 million infections and more than 1.2 million deaths from COVID-19, according to Johns Hopkins University data.
