[THE NEED FOR REDUCING DISPARITIES IN SARS-COV-2 IMMUNIZATION: THE ULTRAORTHODOX AND ARAB POPULATIONS IN ISRAEL].

INTRODUCTION: Immunization against coronavirus disease 2019 (COVID-19) in Israel began on December 2020, using the BNT162b2 mRNA vaccine. Individuals aged 60 years or older and medical staff were prioritized in COVID-19 immunization, and currently individuals aged 16 years or older are eligible to receive the vaccine. To achieve levels of community immunity (herd immunity) immunization of 60-70% of the population is required. As of mid-February 2021, about 42% of the population in Israel received the first vaccine dose, and the coverage exceeded 70% in individuals aged 50 years or older. Despite this success, the rates of COVID-19 immunization are lower in the ultraorthodox and Arab populations compared to the general Jewish population. We reviewed factors that might affect acceptance of COVID-19 vaccines. Factors that might influence the individual's willingness to be vaccinated against COVID-19 include concerns about the safety of the vaccine, recommendations by employers and treating physicians. Moreover, differences were found in the willingness to be vaccinated according to socio-demographic characteristics, such as employment, age and gender groups, and even political affiliation. Minority populations are vulnerable to misinformation about vaccines. The Arab and the ultraorthodox populations are the main minority groups in Israel, and characterized by lifestyle, and low socio-economic status, which increased, among other factors, the incidence of COVID-19 in these populations. To improve vaccine uptake in the ultraorthodox and Arab populations, there is an urgent need for better tailored solutions to the unique needs of these minority populations, which comprise main risk groups for misinformation related to COVID-19 vaccines. Moreover, a better understanding of the reasons for low uptake of COVID-19 vaccine in these populations is warranted. These activities should be undertaken in parallel to continuous efforts towards reducing socio-economic disparities between sub-population groups.
