Neonatal Immunization With Pneumococcal Conjugate Vaccine in Papua New Guinea
Summary
The National Health Plan 2001-2010 calls for investigation of the feasibility of pneumococcal vaccines for Papau New Guinea. The Papua New Guinea (PNG) Institute of Medical Research, the Telethon Institute for Child Health Research and the Department of Paediatrics, University of Western Australia will collaborate to examine very closely the safety of neonatal vaccination, particularly with regard to impact on the development of immunity and response to other vaccines given to infants. This study will also provide a unique opportunity for training of PNG and Australian scientists in both countries.
Description
In order to obtain the earliest possible protection against invasive pneumococcal disease, achieve optimal coverage and reduce burden of early carriage, neonatal pneumococcal conjugate vaccine (PCV) immunization needs to be considered. This study in the PNG highlands will enrol 312 infants at birth, who will be randomised to receive PCV either at 1-2-3 months (infant schedule according to PNG national EPI schedule) or 0-1-2 months of age (neonatal schedule) or receive only routine immunizations (controls). Blood samples will be taken at birth-2-3-4 months of age, pre- and post-pneumococcal polysaccharide booster (23vPPV) at 9-10 months of age (to assess immune memory) and at 18 months at study completion. Carriage will be assessed weekly for the first month of life and at regular intervals thereafter. There will be ongoing surveillance for respiratory and other diseases throughout the study. In addition to serotype-specific IgG, we will examine IgG avidity, IgG subclasses, mucosal IgA and T-cell cytokine responses to PCV and pneumococcal protein antigens. To ensure immunological safety, particularly for neonatal PCV, immune responses to concomitant vaccines and viral and environmental antigens will also be examined as well as overall T-cell maturation.

Medical and Biotech [MESH] Definitions
Pneumonia, Pneumococcal
A febrile disease caused by STREPTOCOCCUS PNEUMONIAE.
Diphtheria-tetanus Vaccine
A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.
Poliovirus Vaccine, Oral
A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)
Brucella Vaccine
A bacterial vaccine for the prevention of brucellosis in man and animal. Brucella abortus vaccine is used for the immunization of cattle, sheep, and goats.
Mumps Vaccine
A live attenuated virus vaccine of chick embryo origin, used for routine immunization of children and for immunization of adolescents and adults who have not had mumps or been immunized with live mumps vaccine. Children are usually immunized with measles-mumps-rubella combination vaccine.
