BACKGROUND Little is known about the impact of the recent varicella vaccine shortage. To assess the temporal trend in varicella vaccine administration before 18 and 24 months of age in a community cohort of children prior to, during and after the recent varicella vaccine shortage. And to compare the temporal trends in varicella vaccinations to trends of an older, more widely accepted vaccine, t...
Large immunization clinics are commonly held to deliver influenza vaccine to seniors and others. Vaccine is typically dispensed from multi-dose vials but pre-filled syringes are now available, offering time savings for vaccinators. To determine if the higher purchase price of such syringes is offset by savings in time and injection supplies, we did a controlled comparison of syringe and vial fo...
BACKGROUND This 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 ...
INTRODUCTION In England, antenatal pertussis immunization using a tetanus/low-dose diphtheria/5-component acellular-pertussis/inactivated-polio (TdaP5/IPV) vaccine was introduced in October 2012. We assessed infant responses to antigens in the maternal vaccine and to those conjugated to tetanus (TT) or the diphtheria toxin variant, CRM. METHODS Infants of 141 TdaP5/IPV-vaccinated mothers in S...
Transfection of modestly immunogenic tumors to express B7 family co-stimulator molecules results in their rejection by syngeneic mice, suggesting a possible clinical application in cancer patients. Immunization of naive mice with irradiated B7-1-transfected P1.HTR cells is sufficient to induce specific cytolytic T lymphocytes (CTL) and to protect against tumor challenge. However, patients to be...
BACKGROUND Parents' knowledge about immunization is an important predictor factor for their children's immunization status. The aims of this study were to assess parents' knowledge and to evaluate the effect of a short educational intervention on improving parents' knowledge of childhood immunization. METHODS A cross-sectional study using a pre- and post-test intervention survey of a single g...
BACKGROUND The development of an HIV/AIDS vaccine has proven to be elusive. Because human vaccine trials have not yet demonstrated efficacy, new vaccine strategies are needed for the HIV vaccine pipeline. We have been developing a new HIV vaccine platform using a live enterovirus, coxsackievirus B4 (CVB4) vector. Enteroviruses are ideal candidates for development as a vaccine vector for oral de...
BACKGROUND Immunization of healthy volunteers during receipt of chemoprophylaxis with Plasmodium falciparum sporozoites (CPS-immunization) induces sterile protection from malaria. Antibody responses have long been known to contribute to naturally acquired immunity against malaria, but their association with sterile protection after whole sporozoite immunization is not well established. We there...
