Geospatial Variation in Rotavirus Vaccination in Infants, United States, 2010–2017

Abstract

We evaluated rotavirus vaccination rates in the United States by using records from a nationwide health database. From data on 519,697 infants, we found 68.6% received the entire rotavirus vaccine series. We noted pockets of undervaccination in many states, particularly in the Northeast and in some western states.

Spatio-Temporal Impact of Self-Financed Rotavirus Vaccination on Rotavirus and Acute Gastroenteritis Hospitalisations in the Valencia Region, Spain.

“…(19) , (18) RV vaccination and hospitalisations could, therefore, vary from time to time and between places for different reasons, including complex interaction of population demographics, socioeconomic inequalities, environmental factors, circulation of RV strains and their interactions across space and time. Spatial variation in RV vaccination coverage (20) and in RV hospitalisations has been previously shown in the USA, Germany, Brazil, New Zealand. The Valencia Region of Spain has approximately 4 900 000 inhabitants.…”

Letter to the editor in response to: Rotavirus vaccine administration patterns in Italy: potential impact on vaccine coverage, compliance and adherence

“…More than 98% of IIS and VSD doses were administered within the recommended 6-32 weeks schedule. Vaccination coverage in the United States (where RV5 is the most widely used vaccine 12 ) has increased since 2007, with the highest vaccination coverage for the complete series achieved by any state increasing from 72% in 2009 to 80% in 2011 and 85% in 2017. 13 Martinelli et al further note that: "Another study conducted within the Medicaid system evaluated compliance rates and adherence to the vaccination schedule in a cohort of 673,956 children under the age of one year, comparing the two approved RV vaccines, HRV [RV1] and HBRV [RV5]".…”
