To this day, almost everyone knows someone who had a serious form of Covid-19 that is requiring hospitalization or even resuscitation, and many families have lost one or more loved ones. In addition, doctors have warned of the risk of collapse of the Healthcare system. In 2020, ethics and the need for care for the population do not allow us to consider this pandemic as benign.

Regulatory agencies, FDA, EMA and MHRA and more agencies, have analyzed the vaccine development in real time and in an extremely rigorous manner. Efficacy results have been exceptional since the FDA required 60% efficacy and the new vaccines have demonstrated 95% efficacy with short-term safety comparable to other existing vaccines.

This is a first of its kind in medicine.

Of course, there are still unknowns about the long-term effects on efficacy and safety. Experts in all fields, including immunologists, hematologists and geneticists, have made the decision to give authorization to use these vaccines, weighing the benefits and the risks of the vaccine against the risk of the disease and emphasizing very close monitoring of the vaccinated individuals.
