MARTINEZ SANCHEZ, Raydel et al. Reactogenicidad e inmunogenicidad de la vacuna cubana inactivada trivalente contra la leptospirosis humana según diferentes esquemas. Rev Cubana Med Trop [online]. 2002, vol.54, n.1, pp. 37-43. ISSN 1561-3054.

A controlled, randomized assay was performed to evaluate the reactogenecity and immunogenecity of Cuban trivalent vaccine against human leptospirosis (vax-SPIRAL) in healthy volunteers, using different vaccination schemes. A Russian-made vaccine was used as control. Adverse effects were local symptoms and signs (pain, rush, local infiltration, itching, necrosis and abscess) and general symptoms and signs(fever, low-grade fever, headache, lipotimia, nausea, vomiting, rash and general malaise). The results showed that the vaccine is innocuous since no serious adverse effects were observed. Low-grade fever and slight local pain were the symptoms and signs that occurred at acceptable levels. Fever was present in a small number of volunteers. Similar adverse reactions were reported in the groups immunized with Cuban vaccine under different vaccination schemes and in those immunized with the Russian-made vaccine. Most of the symptoms and signs disappeared after 72 hours. Seroconversion was similar to other bacterines against leptospirosis. The achieved results allowed concluding that the Cuban vaccine is safe and low reactogenic for human adults.
