1. In a major study, researchers have revealed that nearly a quarter of the world’s population may not have access to a Covid-19 vaccine until at least 2022.
2. The findings, published in the journal The BMJ, suggest that the operational challenges of the global Covid-19 vaccination programme will be at least as difficult as the scientific challenges associated with their development.
3. By 15 November 2020, several countries had reserved a total of 7.48 billion doses, or 3.76 billion courses from 13 manufacturers, out of 48 Covid-19 vaccine candidates in clinical trials.
4. “Just over half (51 per cent) of these doses will go to high-income countries, which represent 14 per cent of the world’s population,” the study authors wrote.
5. Low and middle-income countries will potentially have the remainder, despite these countries comprising more than 85 per cent of the world’s population.Topics #COVID Vaccines #Population
