Teacher:In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.
Teacher: Now, understand the problem? Solve this instance: The antigenicity and protective effect of 3 strains of avian infectious bronchitis virus inactivated by beta-propiolactone were studied. Chickens administered 2 doses of the inactivated Connecticut strain (IBV-46) vaccine by aerosol at 3-week intervals had significant levels of virus-neutralizing antibodies and were resistant to infection by the Massachusetts strain (IBV-41) as determined by virus isolation attempts. Antibody levels in chickens given inactivated Iowa 33 and Iowa 609 were not significant and they were not resistant to infection by IBV-41.
