Multiple vaccine comparison in the same adults reveals vaccine-specific and age-related humoral response patterns: an open phase IV trial

M. V. D. Heiden, S. Shetty, et al.

This study explores the reduced vaccine responsiveness in older adults, revealing critical insights into how age influences humoral responses to various vaccines. Conducted by a team of experts, including Marieke van der Heiden and Sudarshan Shetty, the research highlights the challenges faced by older males in responding effectively to vaccines.

Abstract
Vaccine responsiveness is often reduced in older adults. Young, middle-aged, and older adult participants (n=315) in the VITAL clinical trials were vaccinated with a quadrivalent influenza (QIV) booster, followed by a pneumococcal-conjugate (PCV13) vaccine, and then a SARS-CoV-2 mRNA-1273 vaccine. Booster QIV induced comparable H3N2 hemagglutination inhibition titers across age groups, but primary PCV13 and mRNA-1273 induced lower antibody concentrations in older adults. Humoral response persistence was shorter in older adults for all vaccines. Approximately 10% of participants, mainly older males, were low responders to multiple vaccines. This study identifies risk groups for low vaccine responsiveness.
