RESUMO
Background: Timely administration of vaccines, particularly for hepatitis B birth dose within 24 hours of birth is of immense importance. It is considered as an indicator of quality of immunization programme. This study aimed to assess effect of mode of delivery and type of hospital on immunization among newborns.Methods: This large multi-site study was conducted in Pune district having population of 9.43 million. A total of 13 hospitals were selected which included all government hospitals performing more than five cesarean sections per month, and one government and one private medical college hospital. Cesarean section and vaginally deliveries were enrolled in 1:1 ratio. Their children were followed till discharge. Data were collected by obstetrician or qualified nurse.Results: During study period 3,112 women were enrolled. The relative risk of not getting vaccine Hepatitis B birth dose before 24 hours among cesarean delivered newoborns was 1.08. The relative risk of not getting zero polio and BCG among cesarean delivered newborns was 0.71 and 0.76 respectively. All these differences were significant. The coverage for all vaccines was better in sub district hospitals than others. Coverage of all vaccines in government teaching hospital was better than private.Conclusions: Cesarean section enabled better coverage among newborns probably due to length of stay. Whereas the physical and mental stress after cesarean section resulted lesser coverage of hepatitis B birth dose within 24 hours. Opportunities of timely Hepatitis B birth dose administration were missed probably due to lack of knowledge among health workers about ideal timing.
RESUMO
Background: Hepatitis B is a major public health problem. The efficiency of the vaccine decreases as the time period between the birth and first dose increases. “WHO recommends that all infants should receive their first dose of Hep B vaccine as soon as possible after birth, preferably within 24 hrs. In India the birth dose/ 0 dose coverage was 45% on 2015. Prior to initiation of “Delivery Point Immunization” the birth dose Hep B was 35%. During the course of this programme the challenges and problems faced has been addressed in this study.Methods: It is a prospective observational study for a period of 15 months conducted by postpartum programme department in O&G department. It includes all the babies delivered in the department.Results: After the integration of delivery point immunization with JSY (Janani Surakhya Yojana) programme, the 0 dose hep B coverage was 72%.The coverage of BCG and 0dose OPV remained 89.48%.The most modifiable cause due to which babies were not received 0 dose Hep B vaccine was due to ignorance 36.19% and babies not received due to SNCU (Sick Newborn Care Unit) admission was 36.06%.Conclusions: Initiation of delivery point immunization has definitely increased the 0 dose hep B vaccine coverage. Integration with other maternal and child health programme had further increased the coverage. Though significant percentage of people know about the at birth immunization but are ignorant about the timing of 0 dose hep B vaccine
RESUMO
Background & objectives: This study was undertaken to evaluate a community based programme of antenatal screening for hepatitis B surface antigen (HBsAg) and selective immunization of children commencing at birth, at a secondary care hospital in south India. The primary objective was to assess immunization coverage among children born to HBsAg positive women; secondary objectives were to study the prevalence of HBsAg among antenatal women, prevalence of HBsAg among immunized children (to estimate vaccine efficacy), seroconversion rate and relationship of maternal hepatitis B e antigen (HBeAg) to hepatitis infection. Methods: The prevalence of hepatitis B antigen among antenatal women and immunization coverage achieved with hepatitis B vaccine in a rural block in Vellore, Tamil Nadu were assessed through examination of records. Children born between May 2002 and December 2007 to hepatitis B positive women were followed up for a serological evaluation, based on which vaccine efficacy and the effect of maternal hepatitis B e antigen (HBeAg) on breakthrough infection was estimated. Results: The prevalence of hepatitis B surface antigen among antenatal women was 1.58 % (95% CI: 1.35-1.81%). Vaccine coverage for three doses as per a recommended schedule (including a birth dose) was 70 per cent, while 82.4 per cent eventually received three doses (including a birth dose). Estimated vaccine efficacy was 68 per cent and seroconversion 92.4 per cent in children aged 6-24 months. Maternal HBeAg was significantly associated with either anti-HBc or HBsAg in immunized children, RR=5.89 (95% CI: 1.21-28.52%). Interpretation & conclusions: The prevalence of hepatitis B among antenatal women in this region was low and a programme of selective immunization was found to be feasible, achieving a high coverage for three doses of the vaccine including a birth dose.
RESUMO
Background: Hepatitis B vaccine was introduced in the Universal Immunization Program (UIP) of 10 states of India in the year 2007-08. This assessment was planned and conducted to ascertain the reasons for low reported coverage of Hepatitis B (Hep B) vaccine in comparison of similarly timed diphtheria, pertussis, and tetanus (DPT) vaccine; to identify operational and programmatic challenges in new vaccine introductions, and to derive lessons for further scale up of Hep B vaccination (or for introduction of any new vaccine) in UIP of India. Materials and Methods: Purposive sampling with both quantitative and qualitative data collection. Two districts each were purposively selected from 5 of the 10 states, which introduced Hep B vaccine, in the year 2007-08. A protocol was devised and data was collected through desk review, in-depth interviews and on-site observation at state, districts and facility levels. The assessment was completed in December 2009. Results: Coverage with three doses of Hep B vaccine was lower than similarly timed three doses of DPT vaccine. Poor stock management ("stock outs or nil stocks" at various levels), incomplete recording and reporting, perceived high cost & related fear of wastage of vaccine in 10 dose vial, and incomplete knowledge amongst health functionaries about vaccination schedule were the main reasons cited for reported lower coverage. Hep B vaccine birth dose was introduced in only 3 of 5 states evaluated. The additional reasons for low Hep B birth dose coverage were lack of knowledge amongst Health Workers about birth dose administration, no mechanism for recording birth dose, and insufficient trainings, official communications, and coordination at various levels. Conclusions: This assessment documents challenges faced in the introduction of hepatitis B vaccine in UIP in India and summarizes the lessons learnt. It is concluded that for successful introduction and scale up of any new vaccine in national or state immunization program; clear and timely central level instructions and oversight and improved stock management is required. At state and district levels; quality trainings, effective supervision and monitoring, improving data recording and reporting are key factor for success. The additional focus on Hep B birth dose administration may help in improving coverage. The lessons from this assessment can possibly be utilized for future introduction and scale up of any new vaccine (or other similar interventions) in India or in any other developing country setting.
