Covid19 Immunization Equality

Considering COVID19 the rate of reported cases varies in different neighbourhoods. Some neighbourhoods have a significantly higher rate of cases than others. If a group of vulnerable people live in the same neighbourhood, the health risk will dramatically be higher compared with the same rate of COVID cases in a low vulnerable neighbourhood. The question is that how we can help to balance this risk (generated by the vulnerability of groups of people and the high rate of COVID cases).
