the steps taken by WHO to help distribution of corona vaccine to the different countries.
Answers
Answer:
Nearly 70 poor countries will only be able to vaccinate one in ten people against COVID-19 next year unless urgent action is taken by governments and the pharmaceutical industry to make sure enough doses are produced, a group of campaigning organisations warned today, as the UK begins vaccinations this week).
By contrast, wealthier nations have bought up enough doses to vaccinate their entire populations nearly three times over by the end of 2021 if those currently in clinical trials are all approved for use. Canada tops the chart with enough vaccines to vaccinate each Canadian five times. Updated data shows that rich nations representing just 14 per cent of the world’s population have bought up 53 per cent of all the most promising vaccines so far.
Explanation:
Vaccine developers who have already reported promising phase III trial results against COVID-19 estimate that, between them, they can make sufficient doses for more than one-third of the world’s population by the end of 2021. But many people in low-income countries might have to wait until 2023 or 2024 for vaccination, according to estimates from the Duke Global Health Innovation Center in Durham, North Carolina.
Manufacturers have scaled back their short-term production estimates over time, says Rasmus Bech Hansen, chief executive of Airfinity, a life-sciences market analytics firm in London. But the makers of the three vaccines that seem closest to widespread distribution — AstraZeneca, Pfizer and Moderna — estimate a total production capacity of 5.3 billion doses for 2021, which could cover between 2.6 billion and 3.1 billion people, depending on whether AstraZeneca’s vaccine is administered in two doses or one and a half (see ‘Vaccine pre-orders’). And a vaccine created at the Gamaleya National Center of Epidemiology and Microbiology in Moscow could cover another 500 million people per year outside Russia from 2021, says the Moscow-based Russia Direct Investment Fund, which is supporting its development. (It hasn’t disclosed capacity within Russia.)
