Characteristics of the protective subcellular coccidioidal T27K vaccine.
COCCIDIOIDOMYCOSIS: SIXTH INTERNATIONAL SYMPOSIUM(2007)
摘要
While the whole killed spherule vaccine, protective in mice and monkeys, did not prevent coccidioidal disease in humans, the 27K vaccine, a soluble derivative, retains protective activity in mice with little irritant action. Gel filtration and anion exchange fractions of thimerosal-inactivated spherules (T27K), when administered with alum adjuvant, also protect mice against lethal respiratory coccidioidal challenge. However, the superb protection afforded by T27K antigens is maintained for some 3 months, but may then diminish. This appears unrelated to the aging of the mice. Prolongation of the protective action may require addition of a different adjuvant or administration of booster doses of vaccine.
