Official title
Rapid Vaccination of Hard-to-Reach Populations
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to develop and determine the effectiveness of a multi-level community participatory intervention designed to rapidly immunize hard-to-reach populations, including substance users, within disadvantaged minority communities. Specific Aims of the project are as follows: 1. To identify the relative contributions of personal factors and structural barriers to immunization status in hard-to-reach populations. 2. To estimate the size of the hard-to-reach population in specified disadvantaged urban communities using venue-based sampling, probability-based sampling, capture-recapture methods and modified Delphi techniques. 3. To compare vaccination rates in hard-to-reach populations between neighborhoods that receive a community-based vaccine outreach intervention versus neighborhoods where vaccines are offered through standard public health programs, using an incremental crossover multilevel community intervention design.
