**8. Conclusions**

Before the responsible governments, both at the national and regional levels, promote vaccination campaigns against Covid-19, in the different scenarios that are foreseen in the future, it will be necessary to increase the levels of institutional confidence in the population, in order to guarantee the success of vaccination program(s). Only in this way will it be possible to achieve the desired levels of immunization in the population during this pandemic situation. This will only be possible if, together with the concrete measures that we have proposed to be implemented by the different governments, a concept of prevention is promoted which encourages individual ethical behavior aimed at achieving the good of health for both the individual and for his or her community. This concept of prevention, based on individual responsibility, must include all preventive measures in the spread of Covid-19, including vaccination measures. The success of future vaccination programs against Covid-19 will depend on the assumption of this ethic of responsibility, not only by individuals, but also by the various governments involved.
