BACKGROUND Young adult women find it acceptable to be offered the human papillomavirus (HPV) vaccine postpartum. Little is known about the practice of administering the HPV vaccine during the postpartum period. MATERIALS AND METHODS The Truven Health Analytics MarketScan Commercial Claims and Encounters database was used to develop a cohort of privately insured 18 to 26-year-old women with un...

BACKGROUND Cholera is a diarrheal disease that produces rapid dehydration. The infection is a significant cause of mortality and morbidity. Oral cholera vaccine (OCV) has been propagated for the prevention of cholera. Evidence on OCV delivery cost is insufficient in the African context. This study aims to analyze Shanchol vaccine delivery costs, focusing on the vaccination campaign in response ...

OBJECTIVE To synthesise lessons learnt and determinants of success from human papillomavirus (HPV) vaccine demonstration projects and national programmes in low- and middle-income countries (LAMICs). METHODS Interviews were conducted with 56 key informants. A systematic literature review identified 2936 abstracts from five databases; after screening 61 full texts were included. Unpublished li...

BACKGROUND We compared vaccine coverage achieved by 2 different delivery strategies for the quadrivalent human papillomavirus (HPV) vaccine in Tanzanian schoolgirls. METHODS In a cluster-randomized trial of HPV vaccination conducted in Tanzania, 134 primary schools were randomly assigned to class-based (girls enrolled in primary school grade [class] 6) or age-based (girls born in 1998; 67 sch...

The emergence of duck tembusu virus (DTMUV), a new member of the Flavivirus genus, has caused great economical loss in the poultry industry in China. Since the outbreak and spread of DTMUV is hard to control in a clinical setting, an efficient and low-cost oral delivery DNA vaccine SL7207 (pVAX1-C) based on the capsid protein of DTMUV was developed and evaluated in this study. The antigen capsi...

Pulmonary vaccine delivery has gained increasing attention during the last decade because this vaccination method combines potential advantages such as the fact that it omits the use of needles and may elicit immunity at the port of entry for many pathogens. In this review the current status of pulmonary vaccination, the potential advantages of pulmonary vaccine delivery, the hurdles to overcom...

Strategies to improve vaccine efficacy are still required. The immunogenicity of DNA vaccines is strongly improved by electroporation (EP). The skin is populated with a wide variety of immune cells, making it an attractive tissue for vaccine delivery. Here we describe a method for the EP-mediated intradermal delivery of DNA vaccines in nonhuman primates, as a model for preclinical development o...

Although immunization with two highly efficacious human papillo-mavirus (HPV) vaccines holds great promise for reducing the global burden of HPV-related cancers, the barriers to achieving this goal remain substantial. The cost of HPV vaccination still represents an important obstacle to implementation in many countries but there are several challenges beyond the high cost (1). It has proven dif...

Vaccination, especially mucosal vaccination, is considered to be effective in the management of Helicobacter pylori infections. However, most antigens alone cannot induce immune responses when administered mucosally and need to be co-administered with adjuvants or delivery systems. The current research on the mucosal adjuvant and delivery systems of vaccine against H. pylori, including advantag...

The development of synthetic peptide-based vaccines has many advantages in comparison with vaccines based on live attenuated organisms, inactivated or killed organism, or toxins. Peptide-based vaccines cannot revert to a virulent form, allow a better conservation, and are produced more easily and safely. However, they generate a weaker immune response than other vaccines, and the inclusion of a...
