To investigate the feasibility of using recombinant adeno-associated virus type 1 vector as prophylactic vaccine against HPV16 infection, rAAV1-mod. HPV16L1, the recombinant AAV1 vector containing codon-modified HPV16 L1 gene, was constructed. C57BL/6 mice were immunized with purified rAAV1 vector through intramuscular and intranasal inoculation routes, and the titer of neutralizing antibody was determined by neutralization assay based on HPV16 pseudovirus. The result shows that the single dose of rAAV1-mod. HPV16L1 can induce specific neutralizing antibody in serum through both inoculation routes. Compared with intranasal group, intramuscular group can induce higher titer of neutralizing antibody. Eliciting strong and prolonged neutralizing antibody in serum, the rAAV1-mod. HPV16L1 is one of promising HPV16 prophylactic vaccine candidates.
