A survey on Malaysian’s acceptance and perceptions towards COVID-19 booster dose

Progressive reopening of the economy and declaration of COVID-19 as endemic has relaxed social distancing and mask-wearing necessities in Malaysia. The Ministry of Health of Malaysia reported vaccination rate had reached 86.1% for the first dose and 84.3% for the second dose as of April 2023. However, the uptake of booster doses (third dose or fourth dose) is relatively lower at 68.6% and 1.5%, respectively. A cross-sectional survey was undertaken to study the acceptance and perception of Malaysians towards booster doses in Peninsular Malaysia with participants 18 years old and above by distributing questionnaires at public areas such as government offices, major city train stations, and airports. The study included elderly participants who were not technology savvy. Of 395 survey respondents, 69.4% accepted the COVID-19 booster dose. The results showed that smartphone usage (p = 0.019), living area (p = 0.049), and education level (p = 0.006) significantly influenced the perception of booster dose acceptance among socio-demographic characteristics. Despite experiencing side effects from previous vaccination, 65.9% of respondents still opted to receive booster doses (p = 0.019). The highest deciding factor in accepting booster dose was the need for more clinical studies on COVID-19 booster dose (58.2%) (p = 0.045). In conclusion, the survey demonstrates that greater emphasis on updating and providing more clinical studies regarding the need for booster doses will increase the public’s acceptance of the COVID-19 booster dose.
