1,25-Dihydroxyvitamin D3 (DHVD3) coadministered with monovalent inactivated poliovirus vaccine (IPV) of all 3 serotypes significantly enhances antipoliovirus systemic and mucosal immunity in mice. Although serum immunoglobulin G antibodies are significantly higher in serotypes 2 and 3, and although salivary immunoglobulin A is significantly increased in serotypes 1 and 3, DHVD3 had the most dramatic effect on the level of neutralizing serum antibodies of all 3 IPV serotypes. These findings suggest a possible use of vitamin D3 as an adjuvant for currently used and proposed new Sabin IPVs.
