Abstract
Abstract
To eradicate polio, the use of oral polio vaccine (OPV) should be stopped to avoid circulation of vaccine-derived polioviruses (VDPVs). After OPV cessation, transition to inactivated polio vaccine (IPV) is recommended. This can only be accomplished when IPV induce better mucosal protection. This can be achieved by adding mucosal adjuvant to the IPV formulation. In the present study we used wistar rats to elucidate the adjuvant effect of double mutant heat-labile toxin (dmLT) of E. coli and recombinant cholera toxin (TCTA1T) on IPV. Rats were administered by intramuscular injection of 1.0-0.6-1.0 D-antigen units (DU) of Inactivated Polio type 1, 2 and 3 /rat. The E. coli dmLT and TCTA1T was used as adjuvant and was administered subcutaneously along with IPV. The control groups received IPV alone or PBS. Rats were immunized on days 0, 14 and 28 days. After last vaccination mice were sacrificed and spleen cells and blood were collected. IgA secreting cells specific for Polio Type1, 2 and 3 were measured by ELISPOT. Intramuscular immunization results in robust mucosal response in inactivated polio antigens + dmLT group compared to other groups. Further measurement of antibodies in serum doesn’t show significant difference among IPV and adjuvanted IPV groups. Thus the present data suggest that vaccination with IPV and dmLT results in specific induction of mucosal immunity, which will provide barrier to infection from oral fecal route.
