Achieving compliance with influenza immunization of medical house staff and students: a randomized controlled trial
Article Abstract:
Medical residents and students who are directly offered the influenza vaccine at conferences and clinics are more likely to be vaccinated than those who are offered the vaccine by other methods. A total of 442 medical residents and students were sent a memorandum regarding vaccination, then half of the remaining unvaccinated individuals were sent a personal letter, half of the letter recipients received a telephone call, and the remaining unvaccinated individuals were directly offered vaccination at conferences and clinics. During the three weeks following the memorandum, 87 individuals (20%) were vaccinated. Five weeks after the letter, 61 individuals (34%) who received letters were vaccinated, compared to 30 individuals (17%) who did not receive letters. By the end of the study, 275 individuals (62%) were vaccinated, 29 (7%) refused and 138 (31%) did not receive the notices. The number of individuals who were vaccinated did not increase significantly after telephone notification. Ninety percent of the individuals offered the vaccine at conferences and clinics were vaccinated, and 10% refused.

Control of influenza A outbreaks in nursing homes: amantadine as adjunct to vaccine -- 1989-1990
Article Abstract:
Amantadine may be used in addition to influenza vaccine to reduce the incidence of influenza in high-risk groups. During November and December, 1989, 113 residents of a nursing home were vaccinated against influenza. An outbreak of an influenza-like illness occurred at the end of December. Influenza A(H3N2) virus was isolated from three patients. Twenty-one (19%) of the vaccinated patients became ill, compared to 14 (16%) of 88 unvaccinated patients. When the outbreak was reported to the state health department, the department recommended every resident receive 100 milligrams of amantadine once a day for 10 days. Following the beginning of amantadine therapy, the number of new cases of influenza-like illness dropped from an average of 1.6 per day to 0.3 per day. Five residents experienced side effects, which resolved when the drug was discontinued.
