During an outbreak of avian influenza or swine influenza, influenza vaccination is recommended for:46
people who work in the poultry or pork industries
people in regular close contact with poultry or pigs
Routine seasonal influenza vaccination does not protect against avian or swine influenza. However, it is possible that, if a person is co-infected with avian or swine and human strains of influenza virus, the 2 strains could reassort and form a virulent strain. This strain could then spread from human to human and start a pandemic.47
