Surveillance of the swine influenza vaccination program at the Royal Military College, Kingston

In a prospective study symptoms appearing in a previously healthy population within 6 weeks after inoculation with monovalent swine influenza vaccine (A/New Jersey/76) were tabulated. Of the 703 persons (ranging in age from 17 to 55 years) participating in the follow-up 54% reported experiencing symptoms, usually within 24 hours of vaccination; the symptoms were usually minor and none of the participants displayed evidence of Guillain-Barré syndrome.
