Immunization by aerosol with La Sota strain of Newcastle disease virus.
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.
