Brief Summary:
Evaluation of the safety and immunogenicity immunological reactivity of HIVAC-1e vaccine An additional goal is to determine which dose level of vaccine might be most effective Specific questions to be addressed in this part of the study include Are there adverse reactions to gp160 vaccine when given to vaccinees previously immunized with a vaccinia-recombinant Does gp160 vaccination of prior HIVAC-1e vaccine result in stimulation of neutralizing antibody and other humoral immune responses Does vaccination with gp160 enhance the development of cell-mediated immune responses in HIVAC-1e vaccinees Is the magnitude of immune response to gp160 booster immunization greater following priming with GP160 recombinant vaccinia HIVAC-1e vaccination than priming with three doses of purified recombinant gp160 AMENDED An 80 mcg dose of gp160 has been chosen for the booster because this dose has been shown to be safe and immunogenic in previous trials and allows comparison of the late boost in this protocol with the late boost in the protocol in which patients were primed with three doses of gp160 Original design HIVAC-1e vaccine is a preparation of the envelope protein of HIV the virus that causes AIDS The protein is produced by genetic modification in vaccinia virus The purpose of a vaccine is to produce an artificially increased immunity to a particular disease in this case AIDS Since there is no known cure for AIDS the control of this disease necessitates the development of effective prevention such as vaccines
Detailed Description:
AMENDED An 80 mcg dose of gp160 has been chosen for the booster because this dose has been shown to be safe and immunogenic in previous trials and allows comparison of the late boost in this protocol with the late boost in the protocol in which patients were primed with three doses of gp160 Original design HIVAC-1e vaccine is a preparation of the envelope protein of HIV the virus that causes AIDS The protein is produced by genetic modification in vaccinia virus The purpose of a vaccine is to produce an artificially increased immunity to a particular disease in this case AIDS Since there is no known cure for AIDS the control of this disease necessitates the development of effective prevention such as vaccines
AMENDED Participants in the amended study will be given one injection in the deltoid muscle of gp160 vaccine The injection of gp160 will be given 2 months after the first take with the HIVAC-1e vaccine After each inoculation volunteers will be observed for one hour For four days after each inoculation each participant will be interviewed daily to monitor side effects and asked to record their temperature and symptoms twice daily It is anticipated that a cohort of approximately 20 HIVAC-1e recipients from the participating AIDS Vaccine Evaluation Units will agree to receive the booster immunizations of gp160 and that this number of patients will be adequate to determine the booster effect of gp160 Original design Study patients receive two immunizations one at the beginning of the study and a second one eight weeks later These immunizations are administered by scarification on the arm the same way that smallpox vaccines were given for several years The patients are divided into two groups The control group receives a derivative of the smallpox vaccine that is used to produce HIVAC-1e vaccine The treatment group actually receives HIVAC-1e Whether a patient receives the parent virus or the vaccine is determined randomly by computer and neither the patient nor the physician knows who actually receives the vaccine The group receiving the parent virus and the group receiving HIVAC-1e are then divided into three subgroups receiving different doses of HIVAC-1e in order to test the effectiveness of different doses of HIVAC-1e Following the first inoculation and the booster inoculation eight weeks later patients have the vaccination site covered with a special waterproof bandage until the vaccination site has healed Participants are counseled on how to avoid contact spread of the vaccine virus including hand washing management of the bandage and separation from persons at high risk for the complications of the virus infection Patients are closely followed for the first four weeks following immunization and then followed for a minimum of one year Women are included only if willing to provide continuing information on sexual practices and menstrual patterns and furnish urine samples as appropriate for pregnancy testing on the day ofbefore vaccination and every other week throughout the 56th day after receipt of vaccine At the Johns Hopkins site patients are compensated depending on how far they have to travel as long as they commit to every-other-day visits for the first 30 days This is to change the bandage and check on healing Interested patients should call collect for additional information about travel pay
