SUMMARY

The present study evaluates the humoral and cellular immune responses in 35 volunteers submited to short antirabies vaccination schedules with the Fuenzalida & Palacios vaccine based on the administration of doses on non consecutive days.
The volunteers were divided into two groups. The first group received a total number of five doses given on days 0, 4, 7, 20 and 35. The other group received four doses, the first one being a double dose given on day 0 and than three other single doses on days 7, 20 and 35.
The evaluation of humoral immune response was carried out by serum neutralization (SN) and indirect immunofluorescense (IIF) tests, while the cellular immune response was evaluated by lymphoblastic transformation assay (LTA) and skin test (ST).
According to our results these reduced schedules elicited early and effective humoral and cellulafimmune responses to rabies antigen suggesting that new reduced schedules should be extensively studied in order to give the proper bases to the proposition of changes in the current long-term schedule.

Key words: Antirabies vaccination; Reduced schedule; Cellular immunity.


RESUMO

O objetivo do presente trabalho foi estudar um novo esquema de vacinação anti-rábica humana, com um menor número de doses, administradas em dias não consecutivos (5 doses nos dias 0, 4, 7, 20 e 35).
A avaliação da resposta imune humoral foi feita pela prova de soroneutralização e pela reação de imunofluorescência indireta, enquanto que a resposta imune celular foi avaliada pela transformação linfoblástica em cultura de sangue total e pelo teste cutâneo de leitura tardia.
Foram estudados um total de 35 voluntários, submetidos ao esquema reduzido de vacinação, e os resultados encontrados permitem afirmar que, embora o número de casos seja relativamente pequeno, este novo esquema de vacinação mostrou-se capaz de induzir a produção de imunoglobulinas anti-rábicas, bem como de eli-citar a resposta imune celular ao antígeno rábico.
