The report, published in the April 2001 edition of Journal of Epidemiology and Community Health, notes the initiative's late start prevents associating vaccine efforts with the decrease in HAV infections that followed, but it did serve as a means of enhancing dialogues between gay males, public health workers, and other community members.
Between 1996 and 1997, 15,000 doses of free hepatitis A vaccine were offered to gay male community members in Montreal, Canada. Free hepatitis B vaccines were offered to the men at the same time. R. Allard and research collaborators at several facilities in Montreal sampled three sets of men during that same period: men infected with HAV during the outbreak, men receiving HAV vaccine, and a community sample of gay males in the population.
Ultimately, 10,000 men received the hepatitis A vaccine. "Vaccinees were older than cases, but had many sex partners and comprised more food handlers," described Allard et al.
