Sin embargo, si se dispone de una vacuna prometedora –y si unos ensayos inocuos en voluntarios humanos sanos que no corran riesgo de infección demuestran que no daña–, denegársela a quienes atienden a los enfermos y agonizantes, con gran riesgo para su propia salud, no parece ético.
Yet if a promising vaccine is available – and if safety trials in healthy human volunteers who are not at risk of infection demonstrate that it does no harm – to deny it to those who are tending to the sick and dying, at great risk to their own health, seems unethical.
