“…For example, almost all the low birth weight (LBW) infants had both timely and complete vaccinations compared to normal weight infants. This is contrary to earlier reports where there were delayed vaccination of LBW infants ( 48 , 49 ). This is a concern because mortality of LBW infants has the highest contribution to under five mortality and death from VPDs due to delayed vaccination will be an unnecessary and avoidable added cause of mortality among this group of infants.…”

Nigerian urban slums have a high population of infants with suboptimal vaccination despite previous interventions. Older women traditionally play supervisory roles in infant care in Nigeria but their influence is untapped in infant vaccination. This study sought to determine if training of older women (≥35 years) in urban slum communities in Ibadan, South west Nigeria, and involving them in infant vaccination will improve infant vaccination timeliness and completion. This was a randomized experimental community study and pregnant women in their third trimester, residing in seven urban slum communities were randomized using their antenatal clinics (ANCs) into intervention (six ANCs) and control groups (six ANCs). The older women who will supervise the care of the infants of pregnant women in the intervention group had seven sessions of training on the importance of infant vaccination timeliness and completion. The vaccinations of the infants from both groups were compared from birth till 9 months. Data were analyzed using descriptive statistics and Chi square test at α = 0.05. There were 96 older women, 198 pregnant women (105 in intervention group and 93 controls) and 202 infants (109 in intervention group and 93 controls). Infants in the intervention group (67.9%) significantly had both timely and complete vaccinations compared with those in the control group (36.6%). Vaccines given at birth were the least timely in both groups. More infants whose older women caregiver were married had timely and complete vaccinations. Also, a higher proportion of male infants, low birth weight babies and infants with older women caregiver with at most two children had timely and completed vaccinations but these were not statistically significant. Training of older women caregivers improved infant vaccination timeliness and completion in these urban slum communities. This model may improve infant vaccination in other similar urban slum settings.

“…Studies from other countries have found that infants born most preterm and with the lowest birth weight are less likely to receive vaccinations on time 5,7,13–17,23,28 . This international trend of vaccination delay has been ascribed to parents' and health workers' beliefs regarding preterm and low birth weight infants' frailty 3,23,28,29 . The reason the extremely preterm infants are more likely to receive vaccinations on time in our cohort could be explained by some of them still being hospitalised at the time of vaccination and by the recommendation in Denmark of in‐hospital vaccination for the first childhood vaccination.…”

In Denmark, preterm births (<37 weeks of gestation) comprise 6.5% of annual births, corresponding to approximately 4000 births. 1 Of the preterm infants, 77% are born between weeks 32 and 36, 15% are born between weeks 28 and 32, and 8% are born <28 weeks of gestation. 1 Preterm birth is associated with increased susceptibility to infections due to immunological immaturity and insufficient transfer of maternal antibodies. [2][3][4] Particularly, vaccine-preventable diseases like pertussis and pneumococcal disease compose significant risks with higher incidence and severity for preterm infants.

National Immunization Program-version 2016 (ISIV-NIP-v2016) recommended a 4-dose hepatitis B vaccine (HepB) schedule for preterm birth (PTB) and low birth weight (LBW) infants born to HBsAg-positive mothers. However, the implementation of this immunization strategy in the past five years has not been fully evaluated in China. We reviewed the data of pregnant women and live-born infants from 24 hospitals between 2016 and 2021 in Lu’an, Anhui province, to estimate the prevalence of PTB, LBW, and hepatitis B virus (HBV) infected pregnant women. We analyzed the vaccination status of HepB and HBIG among PTB and LBW infants born to HBsAg-positive mothers. A total of 160 222 pregnant women and 159 613 live-born infants were included in this study. The estimated prevalence of PTB, LBW and HBV-infected pregnant women was 3.86% (range: 3.28%-5.10%), 2.77% (range: 2.12%-3.66%), and 3.27% (range: 3.03%-3.49%), respectively. We screened 340 PTB and LBW infants born to HBsAg-positive mothers between 2016 and 2020. We found that the coverage of HepB and HBIG among them was 100% and 99.39%. However, the timely vaccination rate of the HepB birth dose was only 78.59% and only four children (1.22%) received the 4-dose HepB as recommended by ISIV-NIP-v2016. The 4-dose of HepB for PTB and LBW infants born to HBsAg-positive mothers recommended by ISIV-NIP-v2016 was not fully implemented. A strong public health intervention should be taken to close the policy-practice gap in China in the future.
