Hepatitis B infection is a major global health problem. Sub–saharan Africa is particularly affected. The aim of this study was to determine the prevalence of HBs antigen (HBs Ag) and to assess the hepatitis B vaccine status among medical and paramedical staff at Dschang District Hospital. A descriptive cross-sectional study was conducted at Dschang District Hospital from November 2018 to June 2019. All medical and paramedical staff of the Dschang District Hospital were included, regardless of sex or age, vaccinated and unvaccinated. We assessed the level of knowledge of hepatitis B, investigated hepatitis B markers like HBs antigen (HBs Ag), HBc antibody (HBc Ab), HBs antibody (HBs Ab); we performed HBs Ab assay, investigated hepatitis B risk factors, and low hepatitis B immunization factors, among an average of 171 health personnel aged 36.48 ± 9.58. Of these, 94.7 % said they knew hepatitis B. The prevalence of hepatitis B was 7%. Nursing and paramedical professions were the main concerned by the HBs Ag positivity. The risk factors found in HBs Ag carriers were unprotected sex, scarification and blood exposure accident. There was an association between HBs antigen portage and unprotected sex (P=0.021), blood exposure accident (P=0.021) and piercing (P=0.004). However, there was no association between HBs Ag carrying and age group (P=0.779), sex (P=0.248) and marital status (P=0.779). On the basis of the statements, without a certificate, 57% of the staff said they had already been vaccinated against hepatitis B; of these, 89% had received at least 3 doses of vaccine, of which 53.3% had acquired immunity from HBV. Advanced age (over 40 years) and overweight were associated with a low response to hepatitis B vaccine. In addition, sex and smoking were not associated with low hepatitis B seroprotection. In conclusion, this study found that the prevalence of HBs Ag is still high in our context and low hepatitis B seroprotection in the study population. Hence the need for awareness-raising, systematic screening and vaccination of health personnel, training of vaccinators and monitoring of the vaccination chain.

Vaccine Immunity

Abstract Background: Immunosuppressive drugs, decreased vaccine coverage, aberrant immunity might be factors of low anti-vaccine antibodies in JIA patients. The study aimed to evaluate vaccine coverage, post-vaccine immunity and risk factors of non-protective levels of antibodies against measles, mumps, rubella, hepatitis B and diphtheria in JIA patients. Methods: A prospective study included 170 children diagnosed with JIA aged 2 to 17 years, who received routine vaccinations against measles, rubella, mumps (MMR) diphtheria and hepatitis B. In all patients, the levels of post-vaccination antibodies (IgG) for measles, rubella, mumps, hepatitis B and diphtheria measured with ELISA.Results: Protective level of antibodies were 50% against hepatitis B, 52% - diphtheria, 58% - measles, 80% - mumps, 98% rubella. The best coverage for MMR had patients with enthesytis-related arthritis-85%, compare to oligoarthritis-70%, polyarthritis-69%, systemic arthritis-63%. Diphtheria coverage was 50%, 51%, 46%, 63%, respectively. Incomplete MMR vaccination had 39% patients, treated with biologics, 22% with methotrexate and 14% with NSAID (p=0.025), and 61%, 46%, 36% for diphtheria (p=0.021). Incomplete vaccination was a risk factor of non-protective level of antibodies against measles (HR=2.03 [95%CI: 1.02; 4.0], p=0.042), parotitis (HR=6.25 [95%CI: 2.13; 17.9], p=0.0008) and diphtheria (HR=2.39 [95%CI: 1.18; 4.85], p=0.016) vaccines, as well as JIA category, biologics, corticosteroids and long-term methotrexate treatment for distinct vaccines.Conclusion: Children with JIA may have lower anti-vaccine antibodies levels and required routine check, especially in children with incomplete vaccination, biologics, systemic arthritis and long-term methotrexate treatment.

Objectives: Despite recommendations for vaccination against hepatitis A virus (HAV) and hepatitis B virus (HBV) for all adults at increased risk of infection, several US states have reported increases in HAV and HBV infections among persons who inject drugs. We investigated hepatitis A and hepatitis B vaccination coverage among a sample of persons who reported injecting drugs and had evidence of hepatitis C virus (HCV) infection. Methods: We searched the Wisconsin Immunization Registry for the vaccination records of persons who underwent HCV testing at syringe services programs from January 1 through August 31, 2018, and were reported to the Wisconsin Division of Public Health as having positive HCV antibody test results and a history of injection drug use. We calculated the percentage of persons who were vaccinated according to national recommendations. Results: Of 215 persons reported, 204 (94.9%) had a client record in the Wisconsin Immunization Registry. Of these 204 persons, 66 (32.4%) had received ≥1 dose of hepatitis A vaccine, 46 (22.5%) had received 2 doses of hepatitis A vaccine, and 115 (56.4%) had received 3 doses of hepatitis B vaccine. Hepatitis B vaccine coverage decreased with increasing age, from 88.0% (22 of 25) among adults aged 20-24 to 30.3% (10 of 33) among adults aged 35-39. Conclusions: These findings suggest that most persons who inject drugs in Wisconsin are susceptible to HAV infection and that most persons aged ≥35 who inject drugs are susceptible to HBV infection. In addition to routine vaccination of children, targeted hepatitis vaccination programs should focus on adults who inject drugs to help prevent future infections.

Objective. We assessed progress toward universal infant immunization against hepatitis B, which was first recommended in November 1991. Methods. Multiple data sources were used to describe vaccination policies and trends in infant hepatitis B vaccine coverage. Results. As of June 1993, 51% of the 63 local, state, and territorial immunization programs recommended hepatitis B vaccination of all newborns shortly after birth. The number of first dosages of hepatitis B vaccine administered to infants in public sector clinics increased rapidly from late 1992 to 1993, and at the end of 1993 was approximately two thirds the number of first dosages of other infant antigens. In a nationwide survey of hospital nurseries 47% offered hepatitis B vaccine to all newborns. Of 3982 sampled newborns in these hospitals, 36.2% had been vaccinated before discharge. In San Francisco and Connecticut, where public health officials encouraged hospitals to offer hepatitis B vaccination, first-dose coverage at discharge was 82.3% in 1994 and 69.1% in 1993, respectively. Coverage was higher in healthier infants and lower in infants of older or bettereducated mothers. Results from the National Health Interview Survey demonstrate that three-dose completion at 12 months of age increased from less than 1% of children born in 1989 to 40% of children born in the fourth quarter of 1992. Vaccination at birth increased from less than 1% of infants born in 1989 to 32% of infants born in the second half of 1993. Conclusions. Infant hepatitis B vaccination has expanded rapidly since national recommendations were made; however, universal coverage has not been achieved.
