Covid vaccine, the Viola immunologist: “The third dose only for certain categories of patients”

GERMANY and Israel have announced a vaccination schedule to administer the third dose, joining nations such as Russia, China and the UAE that are already inoculating them (in the case of China and the UAE, the reason is the lower efficacy of vaccines developed with inactive parts of the virus). But alongside the countries that advocate this strategy, there are those who believe that the need for a third dose has not yet been demonstrated at this time.
