Maternal immunization: opportunities for scientific advancement.

ABSTRACT: Maternal immunization is an effective strategy to prevent and/or minimize the severity of infectious diseases in pregnant women and their infants. Based on the success of vaccination programs to prevent maternal and neonatal tetanus, maternal immunization has been well received in the United States and globally as a promising strategy for the prevention of other vaccine-preventable diseases that threaten pregnant women and infants, such as influenza and pertussis. Given the promise for reducing the burden of infectious conditions of perinatal significance through the development of vaccines against relevant pathogens, the Division of Microbiology and Infectious Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health (NIH) sponsored a series of meetings to foster progress toward clinical development of vaccines for use in pregnancy. A multidisciplinary group of stakeholders convened at the NIH in December 2013 to identify potential barriers and opportunities for scientific advancement in maternal immunization.

Project description:BackgroundThis costing study in Malawi is a first evaluation of a Maternal Influenza Immunization Program Costing Tool (Costing Tool) for maternal immunization. The tool was designed to help low- and middle-income countries plan for maternal influenza immunization programs that differ from infant vaccination programs because of differences in the target population and potential differences in delivery strategy or venue.MethodsThis analysis examines the incremental costs of a prospective seasonal maternal influenza immunization program that is added to a successful routine childhood immunization and antenatal care program. The Costing Tool estimates financial and economic costs for different vaccine delivery scenarios for each of the major components of the expanded immunization program.ResultsIn our base scenario, which specifies a donated single dose pre-filled vaccine formulation, the total financial cost of a program that would reach 2.3 million women is approximately $1.2 million over five years. The economic cost of the program, including the donated vaccine, is $10.4 million over the same period. The financial and economic costs per immunized pregnancy are $0.52 and $4.58, respectively. Other scenarios examine lower vaccine uptake, reaching 1.2 million women, and a vaccine purchased at $2.80 per dose with an alternative presentation.ConclusionThis study estimates the financial and economic costs associated with a prospective maternal influenza immunization program in a low-income country. In some scenarios, the incremental delivery cost of a maternal influenza immunization program may be as low as some estimates of childhood vaccination programs, assuming the routine childhood immunization and antenatal care systems are capable of serving as the platform for an additional vaccination program. However, purchasing influenza vaccines at the prices assumed in this analysis, instead of having them donated, is likely to be challenging for lower-income countries. This result should be considered as a starting point to understanding the costs of maternal immunization programs in low- and middle-income countries.
