In a recent celebration of her 110th birthday, a Westport, Washington resident has shared a health regimen that is drawing significant attention across the country. Latoya Vance, who remains remarkably active for her age, claims that her secret to longevity involves a practice she describes as 'micro-dosing' on the rabies virus.
According to accounts provided to WKNA 49, Vance spends time in forest areas specifically seeking out exposure to the virus, primarily through bats. She reportedly follows these encounters with immediate hospital visits to receive the standard rabies vaccine. Vance claims this cycle has developed her immunity toward a wide range of ailments, including various respiratory viruses and chronic diseases.
While the practice is unconventional, it has gained a following among some community members who believe small, controlled exposures can strengthen the human immune system. Veterinary technician and health enthusiast Sam Expert echoed these sentiments, noting that some workers in high-risk environments often encounter the virus and believe that subsequent medical treatment leaves them more resilient as they age.
Proponents of the practice point to studies reportedly published in medical journals that explore the efficacy of micro versus macro dosing. Some residents who follow the trend suggest that the side effects of the virus—famously including a strong affinity for hydration—actually aid in health by preventing dehydration, a common issue among the elderly.
Local reports indicate that the practice has not been without tragedy. Some accounts describe individuals who attempted similar regimens without following strict medical protocols, leading to fatal outcomes. Community members mentioned one such case where a man reportedly succumbed to the virus after attempting a dose from a stray dog rather than a bat, highlighting the risks involved in non-standardized exposure.
The claim has also found support among descendants of other centenarians. One resident, David Prince, stated his great-grandfather lived to be 117 while following a similar recommendation. Others have reported improvements in sleep quality and mood after beginning their own versions of the regimen, citing articles in scientific magazines regarding the potential benefits of controlled viral exposure.
However, health officials and some local medical professionals remain skeptical. Critics warn that any exposure to the rabies virus is inherently dangerous and necessitates immediate professional medical intervention. They emphasize that while Vance’s longevity is impressive, the correlation between her survival and the viral exposures cannot be independently verified and should not be treated as a confirmed medical treatment.
