Factors Associated with Uptake of Hepatitis B Birth Dose Vaccine among Newborns at Mubende Regional Referral Hospital, Mubende District
This mixed-methods study at Mubende Regional Referral Hospital reveals that while Hepatitis B birth dose vaccine uptake (69.4%) exceeds national averages, it remains below WHO targets primarily due to caretakers' lack of awareness, vaccine stockouts, and communication gaps, highlighting the critical need for improved health education and consistent supply to achieve elimination goals.

Every year, millions of babies around the world are born into a world where a silent virus waits to infect them. This virus, known as Hepatitis B, can settle in a newborn's liver and cause serious illness that lasts a lifetime, often leading to cancer or liver failure decades later. The most common way this virus passes from a mother to her child happens right at the moment of birth. Fortunately, science has found a powerful shield against this danger: a single shot of vaccine given within the first day of life. This shot is so effective that it stops the virus from taking hold in more than ninety-five out of every hundred babies who receive it. For years, health experts have urged countries to make this shot a standard part of every newborn's care, aiming for nearly every baby to get it within twenty-four hours of being born. Yet, in many places, this life-saving moment is missed, leaving children vulnerable to a preventable disease.
In the central region of Uganda, a team of researchers set out to understand why this critical shot is sometimes missed, even in a major hospital where care should be readily available. They focused their attention on Mubende Regional Referral Hospital, a large facility that serves hundreds of thousands of people across several districts. While the hospital has better equipment and more staff than smaller local clinics, the number of babies receiving this birth dose vaccine there was still far lower than the global goal. The researchers wanted to know what was happening inside the hospital walls. They asked a simple but vital question: what stops a newborn from getting this protective shot, and what helps them get it?
To find the answer, the team spent a year listening to the people who matter most. They spoke with nearly three hundred parents and guardians who had recently given birth at the hospital, asking them about their experiences, what they knew about the vaccine, and what happened during their stay. They also sat down with doctors, nurses, and midwives to hear the challenges they faced on the ground. The researchers looked for patterns in the answers, comparing the stories of parents whose babies got the shot with those whose babies did not. They were looking for the specific factors that made the difference between a baby being protected and a baby being left at risk.
The study revealed a surprising truth about what drives success in this setting. The researchers found that the most important factor was not how much money a family had, how far they traveled to get to the hospital, or how much formal education a parent had received. Instead, the single biggest predictor of whether a baby received the vaccine was whether the parent knew the vaccine was available at the hospital. When a parent was unaware that the shot existed or that it could be given right there, the chance of their baby receiving it dropped dramatically. In fact, parents who did not know the vaccine was available were far less likely to have their child vaccinated, regardless of their other circumstances. This suggests that the barrier is often a simple gap in information rather than a lack of resources or a refusal to accept medical care.
However, the story is more complex than just missing information. The researchers also uncovered a series of practical hurdles that kept the vaccine from reaching every baby. One major issue was the availability of the vaccine itself. The team learned that the hospital sometimes ran out of doses, particularly during weekends, holidays, or night shifts when supply deliveries were delayed. When the vaccine was missing, the opportunity to protect the baby was lost forever, as the shot must be given within the first day of life. Another challenge was the flow of people through the hospital. With a small team of staff trying to care for dozens of newborns every day, long wait times sometimes meant that mothers were discharged before the vaccine could be administered. Additionally, some healthcare workers were not consistently explaining the importance of the shot to parents, or they were unsure themselves about who should receive it. For instance, some staff hesitated to give the vaccine to babies born with low birth weight, even though medical guidelines clearly state that these infants are safe to vaccinate and need it just as much as any other baby.
The human element played a significant role as well. The researchers found that when healthcare workers took the time to explain things clearly and with kindness, parents were more likely to trust the process and ensure their baby got the shot. Fathers who were present and supportive also made a difference, often helping with transport costs or simply encouraging the mother to follow through with the vaccination. But when communication was poor or when parents heard confusing rumors in their communities, trust eroded. Some parents feared side effects or believed false stories about the vaccine, which led them to delay or refuse the shot. These fears were often fueled by a lack of clear, consistent messaging from the hospital staff.
The findings from Mubende offer a clear path forward. The researchers concluded that while the hospital is doing better than many smaller clinics in the district, it is still falling short of the global goal to protect nearly every newborn. The solution does not require building new facilities or finding vast amounts of new money. Instead, it requires fixing the flow of information and the flow of supplies. Ensuring that the vaccine is always in stock, even on weekends and holidays, is essential. Equally important is training staff to communicate clearly and consistently with every parent, making sure they understand that the vaccine is available, safe, and necessary for all babies, including those born small. By closing these gaps in knowledge and logistics, the hospital can move closer to its goal of protecting every child from a lifetime of illness. The work done here shows that in the fight against disease, sometimes the most powerful tool is simply making sure everyone knows the shield is there and how to use it.
