What drives small-scale farmers to vaccinate their multiple livestock species animals against common infectious diseases in Myanmar?

Abstract

Livestock rearing is an important income source for small-scale farmers in Myanmar, but Foot and Mouth Disease (FMD) and Newcastle disease (ND) are major constraints to livestock production. A study was conducted to identify perceptions of farmers about FMD and ND disease risks and perceptions about vaccination practices by using the modified health belief model. The majority of livestock farmers (>70%) reported that they were aware of the risk and impact of FMD and ND and were willing to vaccinate their livestock (>60%). Focusing on three main livestock farmer groups, about 17.0% of cattle, 15.4% of village chicken, but only 2.3% of small ruminant owners, indicated that the non-availability of vaccinations in the villages was the major constraint to vaccinations (p<0.001), while in contrast twice as many small ruminant farmers compared to cattle and village chicken farmers indicated they had no knowledge about vaccinations and no funds to conduct vaccinations. Limited accessibility to vaccines and vaccinators was related to size of villages (p = 0.001 for cattle; p = 0.027 for small ruminants; p = 0.005 for village chicken). Willingness to vaccinate small ruminants against FMD was associated with the perceived impact of the disease on sales and accessibility of information about vaccination. Accessibility to information about ND vaccination influenced the willingness of village chicken farmers to conduct vaccinations. In addition, beliefs in the effectiveness of vaccinations played a major role in the willingness to carry out vaccinations on both, cattle (β = 0.3, p = 0.018) and village chicken farms (β = 0.5, p<0.001). Our study highlights that policies that increase the accessibility of vaccines and the dissemination of information about disease prevention and vaccination practices in villages of all sizes, have the potential to increase FMD and ND vaccination rates and thereby reduce outbreak occurrence in Myanmar. On the other hand, indirect factors, such as village size strongly influenced the availability of vaccinations.

Utilization of health belief model in comprehending diarrheal disease dynamics: a case of cryptosporidiosis in Uganda

“…The livestock farmers periodically vaccinate, monitor disease signs and symptoms, treatment and promotion of hygiene in homes. This could perhaps be due to the triggers such as ownership and livestock being taken as a source of livelihood for some communities [25]. Therefore, a farmer would do all it takes to ensure that the animals are safe from diseases such as cryptosporidiosis which would rather claim lives of their animals.…”

Foot-mouth disease outbreak and vaccination among beef breeders: a case study in Bone Regency, South Sulawesi

“…The study demonstrated that despite not achieving the desired vaccination coverage, the large-scale FMD immunization program was highly received by participating farmers and was successful in halting the spread of the disease in Laos. According to [16], The main obstacle to vaccination was a lack of vaccine coverage in villages, whereas more than double the number of small ruminant farmers compared to cattle farmers and village chicken farmers said they did not know about immunizations and did not have the resources to perform them. In smaller villages, vaccine availability and vaccine providers were more limited.…”

“…Such interventions have the major advantage or creating accessibility of information. Taking the example of vaccination, a farmer's beliefs in the effectiveness of vaccinations plays a major role in their willingness to carry it out on their own livestock (Win et al, 2021).…”
