At times, reports about medical breakthroughs appear quite odd: a beer-based vaccine, a smart toilet, or a chewing gum diagnostic. However, behind these unconventional formats lie genuine research efforts. We have analyzed three instances where scientific proposals initially provoked amusement but later garnered significant interest.
Virologist Chris Buck, affiliated with the National Cancer Institute, put forward an unconventional method for vaccinating against polyomaviruses—delivery via a beverage featuring a distinctive foam. This group consists of small, non-enveloped viruses containing DNA. They are widespread in nature; estimates suggest that 35 to 90% of the population is infected. In the majority of individuals, polyomaviruses remain asymptomatic, showing no outward signs. Nevertheless, under conditions of severe immunodeficiency, they can become active, potentially leading to serious illnesses and skin cancer.
Buck developed a yeast strain augmented with virus-like particles designed to elicit an immune response. These particles present the pathogen to the immune system without containing the actual virus. Buck tested the vaccine on himself, adding the yeast bearing the particles into homemade beer. According to him, this resulted in the appearance of antibodies against several polyomavirus subtypes in his blood. The scientist intended to submit these findings to a scientific journal, but the Research Ethics Committee of the National Institutes of Health deemed such self-experimentation unacceptable and therefore did not approve the paper. Consequently, rigorous scientific studies on a beer vaccine for polyomaviruses are lacking. Although similar vaccine delivery technologies have long been under investigation, no one had previously progressed to human experimentation.

The Laboratory Toilet

Researchers from Stanford University introduced the concept of a “smart” toilet capable of analyzing feces and urine. The device incorporates sensors, a user recognition system based on fingerprints, and anatomical features.
The toilet can assess physical parameters (volume and flow rate of urination, duration and intensity of the stream, shape and consistency of stool), chemical composition (urine pH, levels of glucose, protein, ketone bodies, erythrocytes, and leukocytes), and microbiological content (presence of pathogenic bacteria and viruses). The researchers suggest that such a toilet could serve as a daily screening tool, aiding in the early detection of intestinal and genitourinary system diseases.
The development successfully operated as a prototype. Subsequently, commercial ventures featuring similar concepts appeared, albeit in limited deployment. In the authors’ view, this technology holds the potential to streamline the prevention of serious health conditions.
Vaccine Gum and Diagnostic Gum
In 2024, a team from the University of Pennsylvania created chewing gum capable of neutralizing influenza and herpes simplex viruses. The scientists engineered this medicinal chewing gum using seeds from the Lablab purpureus bean. This plant contains FRIL, a naturally occurring antiviral trap protein. Laboratory tests indicated that this gum could neutralize 95% of two types of herpes simplex virus (HSV-1 and HSV-2) and two strains of influenza A (H1N1 and H3N2).
This is not the sole application of chewing gum in the service of science. Scientists at the University of Würzburg in Germany fabricated a gum that can determine if an individual has the flu. They synthesized a specific “decoy” molecule and incorporated it into the gum. Laboratory experiments using saliva samples revealed that when the “decoy” encounters neuraminidase (an influenza virus enzyme), thymol (an aromatic compound) is released, imparting a distinct flavor. Notably, this molecule reacts exclusively to the virus, ignoring bacteria.

The main takeaway: Modern medicine frequently surprises with unconventional ideas.
Behind strange concepts like the beer vaccine, the “smart” toilet, or chewing gum lies real science. A creative approach facilitates the search for novel methods of prevention, diagnosis, and drug delivery. While most of these technologies remain at the prototype stage, the future may very well belong to them.
