    ABSTRACT

    Purpose

    To assess adverse neurological risks following influenza vaccination in older adults.

    Methods

    Using a linked database of healthcare administrative claims data and vaccination records from an urban city in Japan (April 1, 2014, to March 31, 2020), we conducted an observational study utilizing a self‐controlled case series design. We identified individuals aged ≥ 65 years who experienced adverse neurological outcomes, defined as hospitalizations related to epilepsy, paralysis, facial paralysis, neuralgia, neuritis, optic neuritis, migraine, extrapyramidal disorders, Guillain–Barre syndrome, or narcolepsy. We used conditional Poisson regression to analyze within‐subject incidence rate ratios, comparing the risk of these outcomes during risk periods following influenza vaccination (0–6 days and 7–29 days after each vaccination) with nonvaccination periods. Our analysis was adjusted for age and season groups as time‐varying covariates.

    Results

    We enrolled 3283 eligible individuals (men: 1643; mean [standard deviation] age: 76 [7.3] years). The incidence rate ratio for the outcome during the risk periods was 0.93 (95% confidence interval, 0.66–1.30) in risk period 1 (0–6 days after vaccination) and 1.14 (0.96–1.35) in risk period 2 (7–29 days after vaccination), respectively.

    Conclusions

    We found no evidence that the risk of adverse neurological events was increased after influenza vaccination in older adults. These results may help reassure older adults who are hesitant to receive influenza vaccination because of concerns regarding adverse neurological outcomes.
