AstraZeneca said on Monday its COVID-19 vaccine could be around 90% effective, giving the world another weapon to fight the global pandemic and potentially cheaper to make, easier to distribute and faster to scale-up than rivals.
The British drugmaker said it will have as many as 200 million doses by the end of 2020 - around four times as many as U.S. competitor Pfizer. Seven hundred million doses could be ready globally as soon as the end of the first quarter of 2021.
The vaccine was 90% effective in preventing COVID-19 when it was administered as a half dose followed by a full dose at least a month later, according to data from late-stage trials in Britain and Brazil. No serious safety events were confirmed, the company said.
The vaccine’s cost works out at just a few dollars a shot, a fraction of the price of drugs from Pfizer and Moderna, which use a more unconventional technology.
And it can be transported and stored at normal fridge temperatures, which proponents say would make it easier to distribute, especially in poor countries, than Pfizer’s, which needs to be shipped and stored at -70C, the sort of temperature typical of an Antarctic winter.
The effectiveness of AstraZeneca’s vaccine depended on the dosing, and fell to just 62% when given as two full doses rather than a half-dose first. But scientists cautioned against seeing this as evidence that it would be less useful than rivals. Vaccines from Pfizer and Moderna each prevented about 95% of cases according to interim data from their late-stage trials.
Strategists at Deutsche Bank described the news from AstraZeneca on Monday as a “big deal,” saying a string of encouraging vaccine developments in recent weeks constituted “an unprecedented victory for science.”
They suggested that emerging markets, most notably Brazil, Mexico, India and Indonesia, were likely to be the “big beneficiaries” of the AstaZeneca vaccine. That’s because “the cheaper cost of production and distribution of AstraZeneca is especially relevant for lower and middle-income countries,” they said.
