Immunization by aerosol with La Sota strain of Newcastle disease virus

Avian Pathol. 1973 Jul;2(3):231-3. doi: 10.1080/03079457309353798.

Abstract

The respiratory symptoms observed after aerosol vaccination with the La Sota strain of Newcastle disease virus were eliminated by mixing the anti-inflammatory compound benzydamine with the vaccine prior to aerosol administration. Benzydamine had no effect on the vaccine virus or on the development of haemagglutination-inhibiting antibodies.
