“…Thus, we can draw attention to the study of Rego et al [ 61 ], which presents the case of Kenya, a country where, according to a survey developed on a sample of 11.569 households, the refusal to be vaccinated decreased over the course of a few months (from 24 % in February 2021 to 9 % in October of the same year). Just like Kenya, Zimbabwe, a low-income country, does not have favorable conditions to deploy the entire arsenal required to completely benefit from vaccination programs; its different social problems (poor education, poverty, weak health system and so forth) have made the Zimbabwean society unwilling to absorb new discoveries in the matter of vaccines, as Muridzo et al [ 62 ] emphasized. Therefore, individualized strategies in territories where there is an asymmetrical distribution in terms of HDI shall be put into practice to increase vaccination coverage, as it is outlined in the case of 196 provinces in Peru, which were analyzed by Al-kassab-Córdova et al [ 63 ]; they identify a direct link between the HDI and the COVID-19 vaccination rate.…”
