The use of an E1-deleted, replication-defective adenovirus recombinant expressing the rabies virus glycoprotein for early vaccination of mice against rabies virus.
An E1-deleted, replication-defective adenovirus recombinant of the human strain 5 expressing the rabies virus glycoprotein, termed Adrab.gp, was tested in young mice. Mice immunized at birth with the Adrab.gp construct developed antibodies to rabies virus and cytokine-secreting lymphocytes and were protected against subsequent challenge. Maternal immunity to rabies virus strongly interferes with vaccination of the offspring with a traditional inactivated rabies virus vaccine. The immune response to the rabies virus glycoprotein, as presented by the Adrab.gp vaccine, on the other hand, was not impaired by maternal immunity. Even neonatal immunization of mice born to rabies virus-immune dams with Adrab.gp construct resulted in a long-lasting protective immune response to rabies virus, suggesting that this type of vaccine could be useful for immunization shortly after birth. Nevertheless, pups born to Adrab.gp virus-immune dams showed an impaired immune response to the rabies virus glycoprotein upon vaccination with the Adrab.gp virus, indicating that maternal immunity to the vaccine carrier affected the offspring's immune response to rabies virus.
