A new study finds that flu vaccination was associated with a 40% reduced risk for Alzheimer’s disease over a four-year period.

Over the course of four years, those who received at least one influenza vaccine were 40% less likely than their non-vaccinated peers to acquire Alzheimer’s disease, according to a new study from the University of Texas Health Science Center at Houston.

Researchers compared the risk of Alzheimer’s disease incidence between patients with and without prior flu vaccination in a large nationwide sample of U.S.

“We found that flu vaccination in older adults reduces the risk of developing Alzheimer’s disease for several years.

The research study – which comes two years after UTHealth Houston researchers found a possible link between the flu vaccine and reduced risk of Alzheimer’s disease – analyzed a much larger sample than previous research, including 935,887 flu-vaccinated patients and 935,887 non-vaccinated patients.

Bukhbinder, MD, a recent alumnus of McGovern Medical School at UTHealth Houston, was first author on the study.

These results underscore the strong protective effect of the flu vaccine against Alzheimer’s disease, according to Bukhbinder and Schulz.

“Since there is evidence that several vaccines may protect from Alzheimer’s disease, we are thinking that it isn’t a specific effect of the flu vaccine,” said Schulz, who is also the Umphrey Family Professor in Neurodegenerative Diseases and director of the Neurocognitive Disorders Center at McGovern Medical School.

Additionally, as more time passes since the introduction of the COVID-19 vaccine and longer follow-up data becomes available, Bukhbinder said it will be worth investigating whether a similar association exists between COVID-19 vaccination and the risk of Alzheimer’s disease.

Co-authors from McGovern Medical School included Omar Hasan, research coordinator in the Department of Neurology and student at The University of Texas MD Anderson Cancer Center UTHealth Houston Graduate School of Biomedical Sciences; Kamal N.

Co-authors from UTHealth Houston School of Biomedical Informatics included Yaobin Ling, graduate research assistant; Xiaoqian Jiang, PhD, the Christopher Sarofim Family Professor in Biomedical Informatics and Engineering; and Yejin Kim, PhD, assistant professor.

Qian Xiao, PhD, MPH, assistant professor in the Department of Epidemiology and Disease Control with UTHealth School of Public Health, also co-authored the study.
