Objective. To analyze factors associated with hepatitis B immunization adherence among adolescents attending a sexually transmitted disease (STD) clinic in El Paso, a city in Texas that in on the border between Mexico and the United States of America. Methods. In this chort study with 248 adolescents we obtained date on demographics and health beliefs through personal interviews and medical record abstraction. We monitored each oof the individuals for 8 determine whether the adolescents received a first, second, and third dose of the hepatitis B vaccine. Results. Overall, 32 of the adolescents received the first immunization, 9 the second, and 2 the thrid. The strongest predictor of receiving either one or two does was providing tha vaccine at the STD clinic as opposed to referring adolescents to a separate vaccination clinic (relative risk (RR)for receiving the first immunization=7.3; RR for receining the second immunization=3.8). several health beliefs were also associated with receiving vaccinations. Conclusions. The results of our study indicate that hepatitis B vaccination programs can be improved throug such steps as providing vaccinations at a convenient site, educating adolescents about hepatitis B risk factors, and emphasizing the difficulty of treating hepatitis B infection

Objective. Due to the lack of correlation from 1994 to 1997 between the A H3N2 componet of the influenza vaccine recomended for this period and the circulating viruses in Argentina, we decided to study the antigenic and genomic relationships of the 1998 A H3N2 Argentine circulating strains with the corresponding vaccine component for that year as recomemded by the World Health Organization (WHO). Methods. We selected 18 influenza A H3N2 strains isolated in Argentina during 1998 to carry out an antigenic and genomic study of their hemagglutinin (HA)AND NEURAMINIDASE (NA)protein. For the genomic study we added 3 isolates froms Uruguay. We compared the Argentine and and Uruguayan strains with available reference strains. Results. We found that all18 strins from Argentina were similar to the A/Sydney/597 (H3N2)strain, as opposed to thr A/wUHAM/395/95 (H3N2) strain, which was the vaccine componet. This result was confirmed by the genomic study. Conclusions. The approach that we applied in Argentina has impoved the quality and quantity of information about influenza in the most appropriate vaccine components each year and provide individuals with the best possible protection against influenza
