abstract: The extreme antigenic lability of the influenza A viruses accounts for the less-than-ideal immune responses to them. With a possible swine flu pandemic in the offing, the "vaccine strategy" required is critical, particularly as the medical and public health communities in the United States embark on the first systematic attempt in history to blunt preemptively the impact of a pandemic.
