The US, Britain, European Union and Japan have so far secured about 1.3 billion doses of potential Covid immunisations, according to London-based analytics firm Airfinity. Options to snap up more supplies or pending deals would add about 1.5 billion doses to that total, its figures show.
“Even if you have an optimistic assessment of the scientific progress, there’s still not enough vaccines for the world,” according to Rasmus Bech Hansen, Airfinity’s chief executive officer. What’s also important to consider is that most of the vaccines may require two doses, he said.
A few front-runners, such as the University of Oxford and partner AstraZeneca Plc and a Pfizer-BioNTech SE collaboration, are already in final-stage studies, fueling hopes that a weapon to fight Covid will be available soon. But developers must still clear a number of hurdles: proving their shots are effective, gaining approval and ramping up manufacturing. Worldwide supply may not reach 1 billion doses until the first quarter of 2022, Airfinity forecasts.
