‘Epidemic is a prisoner’s dilemma’


She noted, however, that game theory assumes that people are rational in their decision-making. Fear can suppress vaccinations to “insufficient levels to prevent outbreaks,” he said.

A 2019 investigation using game theory to study vaccination showed that vaccine contractility could be explained by a math mechanism called “hysteresis”. In general terms, hysteresis occurs when the effects of the force persist even after the force is removed – the reaction stops. The paper clips attached to the magnetic field are still glued together after the field is closed; Recovery Unemployment rates may remain high even in the recovery economy.

Similarly, even after the vaccine is considered safe and effective, the uptake rate is always low.

A doctoral student in mathematics at Dartmouth College Ledge, and co-author of the paper, the mathematician and co-author of the paper, said the “hysteresis effect makes the population vulnerable to vaccine risk.” Biomedical data scientists (who have recently applied a similar approach to the dilemma of social distance).

“It boils down to a fundamental problem known as the Commons tragedy,” Ms. Said Chen. “There is a mismatch between personal interests and social interests.” To address the hysteresis effect, he said, vaccination should be promoted as an act of philanthropy – an individual contribution to defeating the epidemic.

Subsequent repetitions of coronavirus game-theory studies discovered how vaccine adherence affects the number of deaths prevented. If a small subset of the population chooses not to be vaccinated, it affects all of us, says author and poet Dr. His book, A New Index for Disaster Management, contains poems composed of words from his scientific papers.

(One poem, “The Strategy of the Majority” was drawn from his first paper on human-environmental systems, which inspired the current study. The last sentence: “The cost of finding balance is increasing.”)

Sebastian Funk, an infectious disease epidemiologist at the London School of Hygiene and Tropical Medicine, said the coronavirus study highlighted the importance of assessing how the objectives of the outbreak controls could affect human behavior. “Excluding this from infectious disease transmission models can be a big limitation.”
