In the context of limited healthcare budgets In yellow fever,<unk>  with 1/5 of the standard vaccine<unk> , administered intradermally, conferred protection for 10 years, as documented by a randomized clinical trial. In Poliomyelitis,<unk>  has been shown to be effective while reducing overal cost, rendering polio vaccination available to more individuals. In the Covid-19 pandemic In a pandemic wave,<unk>  is considered to accelerate widespread access to vaccination when vaccine supply is limited: In the COVID-19 pandemic, epidemiologic models predict a major benefit of personalized<unk>  strategies with certain vaccines in terms of case load, deaths, and shortening of the pandemic. To reduce side effects In some segments of the population, disease risk is lower but specific vaccine side effect risks may be increased. In such subpopulations,<unk>  might optimize the benefit-risk ratio of vaccination for an individuum and optimize the cost-benefit relation for society.
