Abstract

A phase 2 clinical trial was conducted to evaluate the antibody responses to bovine parainfluenza virus type 3 (bPIV3) vaccination in young infants. Three groups were tested as follows: placebo (n = 66) and 105 (n = 64) or 106 (n = 62) TCID50 of bPIV3. The vaccine or placebo was administered intranasally at ages 2, 4, 6, and 12-15 months, and serum specimens were collected at ages 2, 6, 7, 12-15, and 13-16 months. Serum hemagglutination inhibition (HI) and IgA antibody titers against bPIV3 and human PIV3 (hPIV3) were measured. The results indicate that antibody responses to bPIV3 vaccination are more likely to be detected by the bPIV3 IgA and HI assays than by the hPIV3 IgA and HI assays, that bPIV3-induced antibody response can be differentiated from hPIV3-induced antibody response most reliably by comparing bPIV3 and hPIV3 HI titers, and that bPIV3 vaccine prevents vaccine recipients from developing antibody profiles of hPIV3 primary infection.
