Pfizer reports their Covid-19 vaccine, in conjunction with BioNTech, so far appears 90% effective. With 94 people in the clinical trial having gotten Covid-19 so far, that means people in the control group receiving the placebo were about 10 times as likely to get the virus as someone who had received the vaccine.
The drug maker could reach milestone of 2 months since the second dose for half of trial participants in order to apply for Emergency Use Authorization next week. They report no ‘serious’ side effects in the trial. That’s great news, great progress. And it means we should have great optimism for travel.
