The cost of delivering COVID-19 vaccines in Vietnam.

The implementation of COVID-19 vaccination in Vietnam in 2021 was unprecedentedly challenging in scale and complexity, yet economic evidence on the cost of delivery vaccines thought the program was lacking.

Methods: This retrospective costing study utilized a bottom-up, ingredient-based approach to estimate the cost of delivering COVID-19 vaccines in Vietnam in 2021, from a payer perspective.

Coverage of the expanded program on immunization in Vietnam: Results from 2 cluster surveys and routine reports.

Unlabelled: The Expanded Program on Immunization (EPI) in Vietnam began in 1981 and reached a 87% national coverage rate in 1987. To investigate the vaccination coverage and trends in time of the EPI in Vietnam, 2 vaccine coverage cluster surveys have been conducted in 2003 and 2009. Information on EPI-vaccine coverage in children (aged 0-23 months - 7 y of age), in women of childbearing age and in pregnant women, was collected through '30 cluster surveys' in 2003 and 2009 (according to the World Health Organization (WHO) methodology) and through routine annual EPI coverage reports for the period 2001-2008.
