Vaccines are used to prevent infectious diseases worldwide. Unfortunately, many vaccines, like the flu vaccine, are less effective in older adults. This single-centre open label partially randomised, partially placebo-controlled trial evaluates the differences in immune response between young and older adults after vaccination with a quadrivalent inactivated influenza vaccine and an adjuvanted herpes zoster vaccination. Exploring the underlying mechanisms between the differences in immunogenicity can provide important information for future vaccine development.
