Mothers’ knowledge and attitudes regarding kid vaccination affect uptake, which is the most effective tool and preventative element of infectious disease outbreaks. The current study examines and measures postnatal moms’ immunization knowledge and attitudes. The current investigation used a cross-sectional study design, with 200 postnatal women identified during their postnatal clinic visits. A questionnaire was used to examine the degree of knowledge and attitude of moms about vaccination. The goals were to investigate the degree of knowledge and attitude of the research subjects, as well as the relationship between knowledge and attitude. The relationship between age, education, occupation, and vaccine knowledge score was shown to be statistically significant. However, ethnicity, job, and method of birth had no effect on mothers’ vaccination knowledge in the research. The education, age, and employment of mothers were shown to be related to their attitudes regarding children immunization. There was no correlation between ethnicity, job, or mode of delivery and attitudes about childhood immunization.

More than half of the moms tested had high vaccination knowledge ratings, and more than two-thirds of the mothers evaluated had positive vaccination attitude scores. The major reason for vaccination resistance in Malaysia, however, was religious misinformation and fear of autism.
