A
peer-reviewed study of a Stage 3 trial using the Russian "Sputnik V" COVID vaccine found it was >90% effective 21 days after the first shot.
Each vaccine that makes it across the finish line brings our world that much closer to a new normal :-)
Also, if we want to reduce the proliferation of new COVID variants, we need to vaccinate as many people around the world as possible, and then continue with annual booster shots for the new variants. So we need a global COVID vaccine industry that has the capacity to manufacture and deliver 8 billion doses per year. Reportedly, over 1 billion doses of the Russian vaccine have been ordered by over 50 countries, so Russia will be a big player in this global market.
Controversially, Russia did not wait until its Stage 3 data were publicly available or independently reviewed before pushing out its vaccine, both domestically and internationally. Personally I wouldn't have accepted one of their jabs until now.
I don't expect the US to approve Sputnik V for use here, because of our long-standing geopolitical rivalry with Russia.
China has rolled out its own vaccine also, but I'm not aware of it having been peer-reviewed by a Western publication as yet. They claim 79% efficacy.
The British AstraZeneca vaccine has been approved by the EU and UK, but not yet by the US. AstraZeneca made some notorious mistakes in its earlier Stage 3 trials, so the US turned it down. AstraZeneca started a new Stage 3 trial in the US, let's hope that one goes well.
And the J&J vaccine should be applying for US approval any day now, after the company released preliminary data last week.
Meanwhile in the US we've got the (German) Pfizer and (US) Moderna vaccines, steadily pumping along, 27 million people have received at least their first dose so far.
2021 is the Year of the Vaccine.
