For active immunization of calves with or without maternal antibodies, form the age of 9 days against BRSV and PI3V to reduce the average titer and the duration of excretion of both viruses.
Start of protective immunity: 5 days for BRSV and 10 days for PI3V after a single vaccination.
Protective immunity: 12 weeks after a single dose. The protective immunity over the PI3V fraction may be reduced in animals with maternal antibodies vaccinated before the age of 3 weeks.
