Ponies held in isolation for 40 months were vaccinated and revaccinated with four commercial equine influenza vaccines. Little or no HI antibody was detected after the first inoculation; second and subsequent annual revaccinations produced peak HI antibody titres between 7 and 14 days. Titres fell quickly between 14 and 28 days and less quickly thereafter. The decline of HI antibody appeared to be related more to the initial titre attained and to the period after vaccination than to the composition of the vaccine. The response to a first annual revaccination was superior to that produced by a second annual revaccination. Ether-treated antigens were required to identify primary and secondary responses to the equine-2-component of vaccines.
The observations reported in this paper were obtained as part of a long term surveillance programme designed to monitor the efficacy of influenza vaccines and study the prevalence of influenza and other respiratory viruses among horses in Britain. Inactivated influenza vaccines were found to be effective in protecting horses from disease caused by influenza A/equine-1 but were less successful in protecting horses against influenza A/equine-2. The paper presents the clinical, epidemiological virological and serological findings obtained between 1971 and 1976.

This paper examines the steps which nurses and other health care staff can take to lessen the likelihood that prisoners will take ilicit drugs--both during their sentences and following release. It presents a range of possible approaches, ranging from the relatively straightforward to the sophisticated, from which nurses can choose the most appropriate intervention to use with a particular client.
