RIEUMONT, Emilia Rosa et al. Duration of immune response against VHB in carrier children and mothers, Consolación del Sur. Rev Ciencias Médicas [online]. 2009, vol.13, n.1, pp. 32-41. ISSN 1561-3194.
The Ministry of Public Health in Cuba has set as one of its goals the total elimination of Hepatitis B, and to fulfill this objective, a national program is carried out which started with the vaccination program of children born from hepatitis B carrier mothers back in 1991, covering later all newborn babies in 1992. One of the parameters to evaluate immunogenicity in a vaccine is its post vaccine everlasting response that shows the need or not of a back up dose. Taking into consideration this research, a quantitation of antibody levels against Hepatitis B was done (Anti-HBsAg) in 10 year old children born in 1994, belonging to school centers in Consolacion del Sur, Pinar del Río province, as well as Hepatitis B carrier mothers and their children whose births occured in the same period. The serological samples were evaluated by means of the immunoenzimatic method (ELISA), obtained in the Higher Institute of Medical Sciences and used in the Department of Hepatitis B of the National Center of Medical Genetics. In those individuals who tested negative for HBsAg and with titles of Anti-HBsAg< 10UI/L, a booster was applied and the immunological memory response was evidenced in a 100% of the researched children.
