Introduction

1.1 Background of the Study

The concept of maternal vaccination to safeguard her infant is not new (Cinicola et al.2021). Early on, in the history of public health practice, there were efforts to protect infants through deliberate infection, usually named “variolation” or “inoculation”. We speak of vaccination, of course, in English, a word dating back to the time of the Anglo-Saxons (Boyd, 2022). There has been, from earliest times, a concern among health care professionals to protect the mother’s health, which will lead to the fetus’s good health and also protect infants during their first few months of life. Vaccinating mothers in countries with a high rate of vaccine-preventable diseases will reduce the risk of these diseases (Avila et al.2023).

Protecting young infants from infectious diseases is of growing importance to clinicians and parents (Haiek et al.2021). Thanks to the actions of various organizations and governments, infant mortality has fallen dramatically in much of the world due to improved sanitation, access to medical care, and vaccination against selected childhood diseases (Wolf et al.2023). With these advances, causes of infant death that formerly were uncommon are now proportionately more important. One such cause of infant mortality that is attracting increasing attention, the focus of this essay, is pertussis, or whooping cough. Pertussis is a highly contagious bacterial infection that affects the respiratory system. The disease causes severe complications in young infants and is fatal in a small percentage of reported cases. A whole-cell pertussis vaccine, containing killed whole Bordetella pertussis bacteria, was licensed in the first half of the 20th century and is considered an effective and safe vaccine (Dubois & Locht, 2021).

Immunization during pregnancy aims to protect both mothers and young infants from common infections. A non-systematic high-level search identified in excess of 50 reviews and/or guidelines relating to these programs and about 150 articles from developed countries (Edwards et al.2024). We outline the benefits of protecting a young infant against infections. A potential strategy for reducing spread is to attempt to reduce the duration of carriage or modify the severity of the disease by maternal immunization. However, pertussis can cause very severe disease in neonates, and it may be necessary to administer at least one dose of pertussis vaccine early in the neonatal period to provide immediate protection (González-López et al.2022).

Immunization can provide some immunity to the neonate due to the transfer of transplacental compounds involved in the mother’s vaccination, and it can help protect the neonate when the first vaccine doses are postponed (Verhasselt et al., 2024). Morbidity or mortality from infectious diseases that occur in the first few months of life, at a time of limited exposure and limited immunity, can be prevented or ameliorated through maternal immunization. Despite its universal acceptance in routine practice, a significant percentage of women refuse to accept influenza vaccination during pregnancy. In addition, the time course of possible vaccine risks and potential effects does not allow some vaccine studies to be performed; the relative rarity of unexpected adverse events and the short follow-up times limit maternal immunization studies. Despite these challenges, there is a large number of maternal immunization options available. (Castillo et al.2021) During pregnancy, vaccination is patient-specific and based on age, risk factors, lifestyle, symptoms, and immune status. A high baseline rate of infection may influence the recommendation for a particular vaccine in countries with lower disease rates or vice versa. There are proposed categories for the adoption of vaccines in pregnant or lactating women when the risk to the fetus is present in this setting to an extent that clearly outweighs possible benefits to the mother. Despite these guidelines, vaccines may be administered to pregnant and breastfeeding women if the benefit of vaccination to the expectant mother outweighs the risk to the fetus. Interestingly, there is a growing body of evidence indicating that the benefits of vaccines far outweigh the potential risks (Garg et al., 2021).

1.2 Statement of the Problem

While there are uncertainties concerning the safety and efficacy of maternal vaccinations during pregnancy, and remaining knowledge gaps, the evidence indicates that maternal immunization holds considerable interest and promise in protecting infants’ health (Abu-Raya & Maertens, 2021). Each day across the globe, pregnant women are confronted with decisions about utilizing vaccines and need to weigh the pathogens that vaccines prevent against the risks posed by the vaccines themselves. In pregnancy, these decisions become more complex as the impact of pathogens and vaccines may extend beyond the woman to her unborn child, with potential for further maternal and infant immune programming. Although vaccines provide immunologic protection and historical data indicate reduced vaccine efficacy in very young infants, limited trial data in humans prevents any conclusions at this time regarding maternal immunization impacts on infant health outcomes (Jarvis et al.2020). With the demonstrated capacity of detecting maternal vaccinations and other antenatal therapies in post-licensure data linkages, providing evidence that might enhance antenatal healthcare provider and expecting mother confidence in relation to harm and benefit rates of influenza and pertussis vaccines during pregnancy is clearly desirable. Influencing public health policy above and beyond such personal considerations will be how maternal immunization opportunities are impacted by the outcomes of this work. In order for public health interventions to work, it is recognized that societal concerns along a continuum are to be addressed, from individual to collective health needs in society as a whole (Cattaneo et al.2022). Advanced drivers of society find interest in a visibly healthier populace, which accompanies reduced economic and other disparities, because these trends contribute positively to a nation’s gross domestic product through increased workplace productivity and decreased healthcare costs. Upstream determinants of health often operate in more negative social gradients; that is, the more individuals face conditions in society that reduce health, the more likely they are to become ill or even die prematurely (Raphael, 2024). Reflexes on such intergenerational determinants exist, and it is generally better for society’s health to ameliorate circumstances of poor determinants further upstream, starting in pregnancy if tools are available through such interventions, such as vaccines. Thus, the theoretical points regarding the societal interest of healthier mothers and infants, as well as parental choice and vaccine hesitancy, are addressed, including existing societal concerns regarding immunization during pregnancy based on available scientific evidence.
