Seroprevalence of anti-tetanus antibodies in mothers and cord blood and associated factors in health-care settings in Lao People's Democratic Republic

BACKGROUND

Maternal neonatal tetanus (MNT) was eliminated from Lao People's Democratic Republic (PDR) in 2014. WHO recommends 80% coverage of 2 or more tetanus vaccinations (TT2+) in pregnancy to maintain MNT control. Vaccination coverage in Lao PDR varies among regions although the reasons are not clear.

METHODS

185 pregnant women giving birth in three district hospitals in Savannakhet province, Lao PDR were recruited. A questionnaire was administered to determine factors associated with seroprotection and blood was taken from mother and cord blood to be tested for anti-tetanus antibodies by ELISA.

RESULTS

77% of mothers and 79% of newborns had sufficiently protective antibody titres (>0.5 IU/ml) against tetanus. Only 70% of the mothers received one dose of TT vaccination during antenatal care (ANC) consultation and 45% received the recommended two injections. Although most of the vaccination took place during ANC 1 and 2, many were missed at these time-points. Anti-tetanus seroprotection in the mothers was associated with maternal age, number of ANC visits, number of TT vaccinations during and before pregnancy and gestational age.

CONCLUSION

Seroprevalence of anti-tetanus antibodies in mothers and newborns was intermediate but TT2+ coverage was low in healthcare settings in Lao PDR. TT2+ coverage during ANC is likely to be significantly lower in settings with less robust ANC practices. Missed opportunities to vaccinate in ANC 1 and 2 suggest a need to promote vaccine awareness and vaccination at first ANC visit. A booster dose of TT containing vaccine should be considered for children aged between 4 and 7 years old.

Knowledge, attitudes and practices related to tetanus toxoid vaccination in women of childbearing age: A cross-sectional study in peri-urban settlements of Karachi, Pakistan

Backgound

A higher incidence of neonatal tetanus implies failure of the vaccination program in Pakistan.

Objectives

The objective of this study was to assess knowledge, attitudes and practices related to tetanus toxoid (TT) vaccine in women of childbearing age.

Methods

We performed a cross-sectional survey in peri-urban Karachi, Pakistan, among women of childbearing age, stratified into three mutually exclusive groups as: married pregnant; married non-pregnant; and unmarried. Descriptive and inferential analyses were performed to estimate vaccine coverage and knowledge attributes.

Results

A total of 450 women participated, of which the largest proportion were married and non-pregnant (n = 185/450, 41%). Over 50% of women (n = 258/450) had not received TT vaccine. Most unmarried women (n = 139, 97%) were unvaccinated. Non-vaccination predictors included: women aged <25 years without any formal education (adjusted odds ratio [OR], 2.1; 95% confidence interval [CI], 1.0-4.4), lack of knowledge about free vaccination (adjusted OR, 4.0; 95% CI, 1.64-10.20), poor knowledge of tetanus disease/vaccination (adjusted OR, 4.6; 95%, 2.2-9.6), living with extended family (adjusted OR, 2.0; 95% CI, 1.04-3.96); family non-supporting vaccination (adjusted OR, 5.7; 95% CI, 2.3-13.9); and husband/other family member deciding upon issues related to women's health (adjusted OR, 2.9; 95% CI, 1.3-6.6).

Conclusion

Low coverage of TT vaccine is largely influenced by poor knowledge, family structure and family decision-making in the local communities of Pakistan.

Awareness and attitude regarding breastfeeding and immunization practices among primigravida attending a tertiary care hospital in southern India

INTRODUCTION

Infant mortality rate (IMR) is considered as one of the most sensitive indicators of health status of a community. Infant mortality figures in India are very high and the two important causes which contributes maximum to the IMR is inadequate breastfeeding and immunization. The major cause of death among under five children in India is neonatal sepsis, diarrhea and pneumonia and breast milk is protective against all the three diseases. Immunization along with breastfeeding reduces a significant number of infant and maternal mortality. Disease like neonatal tetanus is rampant in our country and it can be prevented by vaccination of the women during pregnancy. This study tries to find out the awareness and attitude among the primigravida females regarding breastfeeding and immunization.

MATERIALS AND METHODS

This facility based cross-sectional study was conducted among 186 primigravida who came to the hospital for delivery and antenatal check-up during March 2014 in three associated teaching hospitals of Kasturba Medical College, Mangalore, which is situated in coastal South India. Approval was obtained from the Institutional Ethics Committee (IEC) of KMC (Manipal University), Mangalore, India. A pre tested, semi structured questionnaire was used as the data collecting tool.

RESULTS

Majority (n=163, 87.6%) were Hindus followed by Muslims (n=16, 3.2%). Nearly half of the participants (n=92, 49.5%) were in the 21-25 y age group, 54.8% participants were not aware of correct position of baby during feeding and 10.8% (n=20) believed that immunization should be stopped if it showed side effects.

CONCLUSION

Breastfeeding and Immunization is an effective way of reducing child and maternal mortality. The results from our study showed that many participants had lacunae in knowledge and attitude and adequate health education should be given to the pregnant women.
