Who should be vaccinated first according to science?
The order of vaccination is continually debated, but what do the various studies say about it?
The coronavirus vaccination campaign is proving particularly difficult In all countries. The need to vaccinate all citizens starting from scratch and the gradualness with which the doses arrive encourages a debate in which many factors are taken into account, but in this article we are going to stop at the information published by different studies.
At the moment, vaccination with the population most at risk and health workers, despite the fact that some people have committed illegalities and reprehensible acts. But what are the next steps: by age? By job sector?
According to information from epidemiologists at the University of Colorado published in Science, the first step is being the correct one: first to the most vulnerable and then to contagioners, in this case medical or nursing home staff who can transmit the virus to them, in addition to being continuously exposed to it.
In 20 minutes recalled a study conducted by the Norwegian Institute of Public Health which detailed which have been the most infected professionals: toilets and public transport drivers, but also waiters, assistants, shop assistants … This has opened the key debate: once the most vulnerable population is vaccinated, is work the scale to take into account?
In this same message is where the New York University study for the magazine fits Advanced Theory and Simulations that you bet on prioritize those with the highest exposure, a factor in which work is essential when organizing the population.
But here we face a problem, published studies end with different conclusions about who are the most exposed people, there are those where the agriculture or fisheries sectors and in others the social and education workers. And all this without taking into account other aspects, such as differences by sex or age.
From all this information, several notes can be drawn, the first is that the studies do not place politicians among the groups to prioritize, but also that each country is going to take a different direction when organizing vaccination, since the studies lack the necessary temporal distance for their conclusions to sentence the debate.
