The health authorities are working with the idea that between 30% and 40% of the Catalan population, mainly risk groups and essential groups, will be vaccinated by June. Those who are over 80 years old, including the highly dependent, could be vaccinated in a month or two. Although this is a much lower percentage than the one expected by the Ministry of Health, which has set a vaccine immunity of around 70% for the summer, the Government hopes that the protection of the most fragile and also those most exposed to the virus allows for a easing of restrictions within four months. Thus, vaccination could begin to be distributed more widely, using museums and university campuses.
