Two prominent Democratic senators have requested a Government Accountability Office study of why COVID-19 vaccination rates remain far lower among Medicaid enrollees than the general population and what barriers are impeding state efforts to increase immunizations among program beneficiaries, low-income people who have been disproportionately affected by the virus.
Sens. Robert Casey Jr. of Pennsylvania and Ron Wyden of Oregon asked for the inquiry, citing recent stories by KHN and Roll Call that have highlighted the problem and states’ ongoing struggle to raise vaccination rates, according to a letter to the GAO that was provided to KHN. A KHN article published in February reported data from several states — Utah, Washington, Virginia and California — which showed that vaccination rates of the Medicaid population were well below overall state rates. For example, in California, 54% of Medicaid enrollees 5 and older had been at least partly vaccinated, compared with 81% of state residents in that age group.
State and Medicaid health plan officials told KHN that part of the problem was that plans don’t have current addresses or phone numbers for many members, which has made contacting them difficult. In a KHN story published in August, state officials said they were also hampered by a lack of access to data about which members are immunized.
