Do sleep dimensions predict primary and secondary antibody responses to vaccination?

Abstract
The immune system may contribute to associations between disturbed sleep and increased disease risk. Until recently, however, much of the work examining immune correlates of sleep employed in vitro measures of immunity of unknown clinical relevance. To address this limitation, we prospectively examined associations of several sleep parameters (sleep duration, efficiency, and quality) with the magnitude of primary and secondary antibody responses to the hepatitis B vaccination series among a community sample of 125 relatively healthy, older adults. Participants completed electronic sleep diaries for 7 consecutive days (3 days prior, the day of, and 3 days following) at each of the 3 hepatitis B injections. In addition, a subset of participants (n=104) wore an actigraph on the 3 days prior and 3 days following the first injection to provide an objective measure of sleep behavior. In regard to primary antibody responses following the first dose of the vaccine, poorer sleep efficiency, greater sleep fragmentation, and greater night to night variability in sleep duration were associated with higher antibody responses; however, these associations were reduced after adjustment for sociodemographic covariates, including age, gender, race, and body mass index (BMI). In contrast, shorter sleep duration, measured via actigraphy alone or averaged across all available nights of sleep assessment, was associated with lower secondary antibody levels, assessed 5-months after the second injection, and a poorer likelihood of being a clinically protected at the conclusion of the vaccination series. Participants with low and high variability in sleep duration also displayed lower secondary antibody levels and decreased likelihood of being clinically protected. These findings remained largely significant after adjustment for sociodemographic covariates. Taken together, these findings provide preliminary evidence for the influence of sleep on primary and secondary antibody responses to the hepatitis B vaccine. Further exploration of the role of poor sleep in susceptibility to infectious illness is warranted.
