Infectious diseases are a major cause of illness and death among older adults. Vaccines can prevent some of these diseases but the uptake of vaccination among older adults varies across settings and groups. Communication with their healthcare worker can help older people makes decisions about vaccination and this is explored in the July 2021 Cochrane qualitative evidence synthesis of healthcare workers’ perceptions and experiences of communicating with people over 50 about vaccination. In this podcast, two authors of this synthesis, Simon Lewin from the Norwegian Institute of Public Health and the Norwegian University of Science and Technology, and Claire Glenton from the Western Norway University of Applied Sciences, discuss why they did the review and what they found.
