An HIV Vaccine Preparedness Study
Summary
The purpose of this study is to estimate the rate at which a certain population becomes infected with HIV. The individuals examined in this study are people who are expected to take part in future studies of HIV vaccines and nonvaccine HIV prevention studies. This study also examines the chances of becoming HIV-positive based on certain risk factors under conditions that are similar to the conditions that would exist in HIV vaccine and non-HIV prevention studies.
Before studying the effectiveness of a potential HIV vaccine, it is important to learn about the range of HIV risk behaviors in the potential participants of these studies. The probability of HIV infection associated with these risk behaviors should also be examined. This study is designed to increase the ability of HIVNET to put into place HIV prevention trials, to increase the diversity of trial participants, and to target populations at highest risk for HIV infection.
Description
Vaccine preparedness studies are necessary in order to prepare for launching preventive HIV vaccine efficacy trials. It is important to gather information on the risk of HIV infection among recruited populations, the extent and stability of HIV risk behaviors in these populations, and the risk of HIV infection associated with risk behaviors. This vaccine preparedness study is designed to expand the capacity of the HIVNET to implement HIV prevention trials, increase the diversity of its participant population, and further target populations at highest risk of HIV infection.
Participants complete a total of 6 scheduled study visits: 2 at baseline, 2 at follow-up 6 months later, and 2 at follow-up 12 months after enrollment. Participant risk behaviors and knowledge of and attitudes toward HIV vaccine and other HIV prevention trials are assessed at each time point. HIV infection status is tested by standard HIV ELISA and Western blot at follow-up, as well as at participant request throughout the study. Participants are instructed to recognize and report suspected primary HIV infection based on symptoms or high-risk exposures. HIV pre-test, risk reduction, and post-test counseling is provided in accordance with CDC standards of practice. Participants who become infected with HIV during the study are counseled and referred for medical and psychosocial services.

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.
Measles 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 measles or been immunized with live measles vaccine and have no serum antibodies against measles. Children are usually immunized with measles-mumps-rubella combination vaccine. (From Dorland, 28th ed)
