Abstract
The gap between the number of vaccines administered in rich countries and in the developing world “is growing every single day, and becoming more grotesque every day”, declared Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization (WHO), on March 22. The latter statement referred to the fact that only 0.1% of the doses of vaccines distributed in the world had been received by the 29 poorest countries, which represent 9% of the global population.
