L’World Health Organization (WHO) called on states later in the vaccination campaign to postpone the boosters. The logic of the request of the international institution dedicated to health, communicated through the words of the director of the agency, Tedros Adhanom Ghebreyesus, it may not be immediate. Why is the WHO, whose purpose has never been of primary importance as in recent years, launches an appeal to stop immunization?
Because the WHO has called on rich countries to postpone the third dose of the vaccine
As the Delta varianteven if herd immunity is achieved, no country is truly safe. The mutation isolated for the first time in India, 40 to 60% more contagious than the Alpha variant, itself 50% more contagious than the original Wuhan strain, is capable of resist – in part – vaccines (here all the data on the effectiveness of the preparations based on the latest studies).
Despite community protection against coronavirus has not been compromised from the most transmissible lineage, many experts draw attention to what is happening in countries that have not had access to the large supplies of doses guaranteed by pharmaceutical companies to richer countries, such as Italy, Great Britain or the United States.
Beyond, of course, the human tragedy, many experts underline that it is in everyone’s interest, even rich nations, to stop the circulation of COVID in the poorest countries, some of which are very populous and dense, such as India and Brazil. In fact the more the virus circulates, the more it mutates. The more there is the risk of the mutation that can test vaccine protection.
WHO’s appeal a stop the vaccination campaign of advanced nations is therefore explained by the urgency to allow the immunization of at least 10% of the population of every country in the world: “We urgently need to change things: from a majority of vaccines that go to rich countries to a majority that goes to poor countries ”, was the reminder of the agency’s number one, who would prefer to secure the elderly and the frail all over the world.
How the United States has responded to WHO requests
White House spokesman Jen Psaki rejected WHO’s request for a moratorium on third doses of the vaccine. The urgency in the US is therefore to vaccinate everyone. More than four billion doses of the vaccine in total which have been administered around the world, beyond the80% was used in high- and middle-income countries, which represent less than half of the world population
On the times to be respected in order not to leave uncovered the immunized who have made the recall and are waiting for the third dose, the Istituto Superiore di Sanità has instead expressed itself: this is what the latest studies taken into consideration by the ISS say to measure the duration of the immune response in people immunized with a full cycle
