New Study Shows Vaccines Can Reduce Risk of Developing Alzheimer’s Disease
According to a recent study conducted by researchers at the University of Texas Health, getting vaccinated against various diseases can have a positive impact on memory and reduce the risk of developing dementia, specifically Alzheimer’s disease. The findings suggest that people over the age of 65 should prioritize vaccination to protect their cognitive health.
The study focused on the effects of different vaccines on Alzheimer’s risk, including those against influenza, diphtheria, tetanus, whooping cough, herpes, and shingles. The researchers found that those who had received the influenza vaccine one or more times had a 40 percent lower risk of developing Alzheimer’s compared to their unvaccinated counterparts.
Neurologist Paul Schulz, who initiated the study, wanted to determine if the influenza vaccine was the main cause of this reduced risk. To investigate further, the researchers conducted a large-scale retrospective study with participants over the age of 65 who did not have dementia at the beginning of the eight-year follow-up period. The study compared two groups: one that had received vaccinations against specific diseases and another that had not.
The results showed that, in addition to the influenza vaccine, the whooping cough vaccine was the most effective in reducing the risk of Alzheimer’s, with a 30 percent lower risk. The vaccines against herpes and pneumococci also demonstrated a 25 to 27 percent risk reduction. Schulz emphasizes that these findings highlight the effectiveness of multiple adult vaccines in preventing Alzheimer’s.
While the study does not establish a causal link between vaccines and Alzheimer’s, the researchers propose a hypothesis for why vaccines may contribute to reducing the risk of the disease. Avram Bukhbinder, co-author of the study, suggests that vaccines may alter the immune system’s response to the accumulation of toxic proteins associated with Alzheimer’s. This could improve the efficiency of immune cells in clearing these toxic proteins or minimize collateral damage to healthy brain cells.
However, proving this hypothesis would require withholding vaccinations from individuals, which raises ethical concerns. Nonetheless, these latest findings add to the growing body of evidence supporting the potential benefits of vaccinations for cognitive health.
As the study highlights the positive effects of vaccines on reducing the risk of Alzheimer’s disease, it further emphasizes the importance of vaccination, especially among older adults. By actively protecting their immune system through vaccinations, individuals can potentially lower their chances of developing this devastating disease.]
