Research into the development of vaccines against Covid-19 continues. However, there is already debate on the strategy to be used to vaccinate the population. It is clear that scientists do not agree among themselves and that there are different strategies.
Most research teams say they can achieve the launch of a vaccine within one to two years . Let us quote all the same the University of Oxford (United Kingdom) having recently indicated that it will be able to finalize a vaccine by September 2020. Obviously, there are still a few steps to validate before arriving at this point, but the researchers seem confident.
Thus, no vaccine is ready yet, but various researchers are currently debating how to vaccinate the population . According to a Wired article published on May 12, 2020, experts are not in complete agreement on the hierarchy to be put in place for the administration of the vaccine. Should we give priority to the elderly, to young people, to people considered vulnerable or to healthcare workers?
Obviously, the success of the development of a vaccine will undeniably lead to its marketing . However, it will obviously not be possible to vaccinate everyone at the same time. Choices will therefore have to be made. For example, it would be possible to vaccinate the elderly first, that is to say the most vulnerable to Covid-19. On the other hand, vaccinating the nursing staff will not risk losing these very important people in the medical field. In addition, Latinos and African Americans are particularly affected in the United States. We can therefore also consider them as a population at risk and vaccinate them first.
Another strategy concerns herd immunity, which could be achieved by vaccinating people with the best immune systems. These people do not need much protection but could indirectly protect others . The idea sounds pretty incredible but is taken seriously by various doctors.
Another question remains:why develop a single vaccine, when many possibilities are being studied? In reality, it is incumbent to prepare several types of vaccines , in particular to gradually benefit from better quality compared to their first versions. The future will inevitably tell us when one or more vaccines will emerge and what the vaccination strategy will be. Will it be the same in all countries? No one is able to say for the moment.
