Malaria Vaccine: Knowledge, Acceptance and Barriers Among Mothers of Under- Five Children in Owerri, Nigeria: A Cross-Sectional Study
This cross-sectional study of 311 mothers in Owerri, Nigeria, reveals that while knowledge and willingness to vaccinate against malaria are high, actual awareness remains low and uptake is primarily hindered by the need for spousal permission and safety concerns, necessitating targeted male engagement and community mobilization for successful vaccine rollout.

Malaria is a relentless disease that still claims the lives of countless young children across sub-Saharan Africa. It is caused by a microscopic parasite carried by mosquitoes, and for decades, the primary defenses have been bed nets, insecticides, and medicines to treat the fever. While these tools have saved lives, the disease has not gone away, and in many places, it is still rising. In recent years, scientists have developed vaccines to fight this parasite, offering a new layer of protection. However, a vaccine is only as effective as the number of children who actually receive it. For a vaccination program to succeed, the people who care for the children must know the vaccine exists, understand how it works, and feel confident enough to bring their children in for the shot. This is where the human element becomes just as critical as the science itself.
In Owerri, a city in southeastern Nigeria, researchers set out to understand the mindset of mothers regarding this new malaria vaccine. They focused on the mothers of children under five years old, the group most vulnerable to the disease. The team visited a large teaching hospital where these mothers regularly bring their children for check-ups and immunizations. They spoke with 311 mothers, asking them a series of questions to gauge what they knew about the vaccine, where they had heard of it, and whether they would be willing to vaccinate their own children. The goal was not just to count heads, but to uncover the specific thoughts, fears, and family dynamics that might help or hinder the rollout of this life-saving tool.
The results revealed a picture of high hope mixed with significant gaps in information. When asked about the basics of the vaccine, the vast majority of mothers demonstrated a strong understanding. More than eight out of ten mothers knew that the vaccine protects against malaria, that it is given to young children, and that it can prevent serious illness and death. Their knowledge was particularly strong regarding the cause of malaria itself, with nearly everyone correctly identifying the mosquito bite as the source of the infection. However, when the questions turned to the practical details of how the vaccine is given, the knowledge dropped sharply. Less than half of the mothers knew that the vaccine is administered as an injection into the muscle. This suggests that while the general idea of the vaccine is understood, the specific instructions on how it works are not yet clear to everyone.
Awareness of the vaccine's existence was the most significant hurdle. Only about half of the mothers had heard of the malaria vaccine before the researchers spoke to them. For those who had heard of it, the hospital or health clinic was the most common source of information, followed by the internet and friends or family. A large portion of the mothers remained unsure whether the vaccine was actually available in their area, reflecting the fact that the national rollout was still in its early stages. Despite this lack of widespread awareness, the willingness to use the vaccine was overwhelmingly high. Nearly ninety-two percent of the mothers said they would be willing to vaccinate their child. The primary reason for this willingness was a simple, powerful desire to prevent their children from getting seriously sick with malaria. Many also noted that the vaccine being free of charge and part of the standard immunization schedule made it an attractive option.
The small group of mothers who said they would not vaccinate their children pointed to very specific barriers. The most common reason was not a fear of the vaccine itself, but a requirement for permission from their husbands. In many of these households, the final decision rests with the male partner, and without his approval, the mother feels she cannot proceed. Other concerns included doubts about whether the vaccine had been tested enough to be safe, and in some cases, the influence of mothers-in-law in family decision-making. Interestingly, the researchers found that a mother's education level or income did not predict whether she would accept the vaccine; the willingness to vaccinate was high across all social groups. This suggests that the barrier is not a lack of interest or understanding among the poor or less educated, but rather a structural issue of access and family dynamics.
The study concludes that the people in this region are ready for the malaria vaccine. The resistance is not coming from a lack of trust or a refusal to accept new science. Instead, the challenge lies in ensuring that information reaches everyone, clarifying exactly how the vaccine is given, and engaging the entire family, particularly fathers, in the conversation. The high level of acceptance indicates that if the vaccine is made available and the community is properly informed, the uptake could be rapid. The path forward involves strengthening the role of health workers as trusted messengers and creating campaigns that address the specific need for spousal approval, ensuring that the desire to protect children translates into actual vaccination for every eligible child.
