Why won the annual flu vaccine protect people against pandemic influenza?
Influenza vaccines are designed to protect against a specific virus, so a pandemic vaccine cannot be produced until a new pandemic influenza virus emerges and is identified. Even after a pandemic influenza virus has been identified, it could take at least six months to develop, test and produce vaccine.
