Parental Knowledge Toward Meningococcal Disease and Vaccination in Makkah Region, Saudi Arabia: A Cross-Sectional Study.

Background Invasive meningococcal disease (IMD) is a bacterial infection caused by Neisseria meningitidis, which primarily affects the meninges, with a high incidence in young children. The most effective technique for preventing IMD is vaccination, which has been available for over 40 years through meningococcal polysaccharide capsule-containing vaccines. This study aims to assess the parental knowledge of meningococcal disease and vaccination in the Makkah region of Saudi Arabia. Methodology A cross-sectional study was conducted between September and December 2023 among 597 parents in the Makkah region using a validated online survey. The collected data were analyzed using the Statistical Package for the Social Sciences (SPSS). Results The study sample included 597 parents, of which 339 (56.8%) were female and 258 (43.2%) were male. Our research demonstrated that 388 (65%) participants had an insufficient understanding of IMD, while 209 (35%) had a sufficient understanding. There was a significant correlation between the knowledge score and the completion of the routine vaccination and whether vaccinating a child is essential for the protection of other members of society. Conclusions Based on our study, only around one-third of the participants demonstrated a sufficient level of knowledge regarding IMD and its vaccination. To provide a more accurate assessment of the Saudi population, additional research should be conducted in various regions and cities.
