To get out of the Covid nightmare, every country must have extensive vaccination coverage. This concept is clear to Boris Johnson who, over the weekend, said he will urge G7 leaders to speed up the vaccination campaign around the world by the end of 2022. Ambitious goal, but is it feasible? It depends on the definition that one wants to attribute to the words of the British Prime Minister.
Aim for herd immunity
In reality, 100% coverage will be impossible: no country will vaccinate every single adult, so the real goal is to vaccinate enough to obtain herd immunity that could come once the two doses have been injected to 60% or 70% of the world population. A possible goal to be achieved by December 2022, experts say, but only if the leading economies of the G7 are currently on the right path to get out of the nightmare: so far, 75% of vaccines in the world have been distributed in just 10 countries.

The Covax program and the bad stop
The United Nations Covax program seems to be the road to vaccination for low-income countries, to date Covax has signed contracts with manufacturers to purchase 2 billion doses by the end of this year. But the first obstacles have arisen: the main supplier is the Serum Institute of India, which is now producing vaccines in response to the dire wave of internal cases and deaths in India and will not be able to fulfill its contracts with Covax or individual countries before the end of 2021. The UK has bought enough doses to immunize the ‘entire population several times: more than 500 million doses of eight different vaccines and the British government has promised to donate the surplus to Covax following the problems that arose in the Serum Institute.

The problem is that the doses can be sent from December but experts suggest starting immediately with donations: especially in the face of the great wave of coronavirus that is rising in Nepal, in India and for the potential concern about the increase in cases in Africa, where precise counts are not always possible. By the autumn, there should be an increase in vaccine production and supplies will reach low-income countries.

The need for infrastructure
Together with vaccines however, an effort in infrastructure will also be requiredThere are few clinics and administration points within many low-income countries and there is a risk that incoming doses may be in excess and expired. The solution is to receive constant supplies so that systems that work can be built and that would require training a workforce and international funding. AstraZeneca, which aims to be the leading low-cost global vaccine, has contracted with over 20 of the world’s leading vaccine factories including the Serum Institute in India.

“Vaccinating the world is not ambitious but necessary”
Romilly Greenhill, UK director of the international non-profit organization One, said the goal of vaccinating the world might seem ambitious, but it is all the more necessary: actually we have to aim for some sort of global herd immunity – 70% coverage – a type of levels, by the end of next year ». Greenhill then added that the risks of a world not covered by vaccines is high: “we could find ourselves with some variants and with increases in infections. We need the G7 to really step forward and commit to the plan, the resources, which are necessary to achieve this goal ».
