Pfizer’s Covid-19 vaccine seems very effectiveEuropost
Pfizer announced on Monday that its experimental Covid-19 vaccine was more than 90% effective, Reuters reported. Pfizer and its German partner BioNTech are the first drugmakers to release successful data from a large-scale clinical trial of a coronavirus vaccine. If proved, it would be a major victory in the fight against the pandemic.
“Today is a great day for science and humanity,” Albert Bourla, Pfizer’s chairman and CEO, said. “We are reaching this critical milestone in our vaccine development program at a time when the world needs it most with infection rates setting new records, hospitals nearing over-capacity and economies struggling to reopen.”
The companies said they have so far found no serious safety concerns and expect to seek US authorisation this month for emergency use of the vaccine. If authorised, the number of doses will initially be limited and many questions remain, including how long the vaccine will provide protection. However, the news provides hope that other Covid-19 vaccines in development may also prove effective.
Pfizer expects to seek broad US authorisation for emergency use of the vaccine for people aged 16 to 85. To do so, it will need two months of safety data from about half the study’s 44,000 participants, which his expected late this month.
