Even after two doses of the vaccine, it is possible to be infected with covid-19. No vaccination offers complete protection against an infection. This episode discusses why this is the case and why protection against the virus decreases over time especially in the elderly.

The Science in a Minute project carries on. Promoted by the Swiss School of Public Health, it aims to provide, through a series of short videos, some of the answers to the most frequently asked questions about scientific facts and topics related to public health in order to make them clear and accessible to everyone.

Dr Rebecca Amati, project manager of the Corona Immunitas Ticino project, guides us on this path, explaining complex concepts and processes in layman's terms. The series is constantly updated according to the evolution of the pandemic. A weekly one-minute clip tackling a different topic will be available.
