Intranasal vaccination of pigs against Aujeszky's disease: comparison with inactivated vaccines in pigs with low maternal antibody titres.
Intranasal vaccination with an attenuated Aujeszky's disease virus strain was compared with parenteral vaccination with two inactivated virus vaccines, in 10-week-old pigs with low levels of maternal antibody. Intranasal vaccination conferred a much better protection than parenteral vaccination with the two inactivated vaccines against challenge two months later, as evidenced by shorter periods of growth arrest and fever and a greater reduction of virulent virus shedding after challenge-exposure.
