The coronavirus disease 2019 (COVID-19) pandemic has set a precedent for the fastest-produced vaccine as a result of global collaboration and outreach. This study explored Malaysians' acceptance of the COVID-19 vaccine and its associated factors.
A cross-sectional anonymous web-based survey was disseminated to Malaysian adults aged ≥18 years old via social media platforms between July 10, 2020 and August 31, 2020.
In the analysis of 4,164 complete responses, 93.2% of participants indicated that they would accept the COVID-19 vaccine if it was offered for free by the Malaysian government. The median out-of-pocket cost that participants were willing to pay for a COVID-19 vaccine was Malaysian ringgit (MYR) 100 (interquartile range [IQR], 100) if it was readily available and MYR 150 (IQR, 200) if the supply was limited. Respondents with a low likelihood of vaccine hesitancy had 13 times higher odds of accepting the COVID-19 vaccine (95% confidence interval [CI], 8.69 to 19.13). High perceived risk and severity were also associated with willingness to be vaccinated, with adjusted odds ratios of 2.22 (95% CI, 1.44 to 3.41) and 2.76 (95% CI, 1.87 to 4.09), respectively. Age and ethnicity were the only independent demographic characteristics that predicted vaccine uptake.
Public health strategies targeting perceived risk, perceived susceptibility and vaccine hesitancy could be effective in enhancing vaccine uptake.
2019冠状病毒病（COVID-19）大流行开创了全球合作与推广下最快生产出疫苗的先例。本研究探讨了马来西亚人对COVID-19疫苗的接受情况及其相关因素。
2020年7月10日至2020年8月31日期间，通过社交媒体平台向年龄≥18岁的马来西亚成年人开展了一项基于网络的横断面匿名调查。
在对4164份完整回复的分析中，93.2%的参与者表示，如果马来西亚政府免费提供COVID-19疫苗，他们会接受。如果COVID-19疫苗随时可得，参与者愿意支付的自付费用中位数为100马来西亚林吉特（四分位间距[IQR]，100）；如果供应有限，则为150马来西亚林吉特（IQR，200）。疫苗犹豫可能性较低的受访者接受COVID-19疫苗的几率高出13倍（95%置信区间[CI]，8.69至19.13）。高感知风险和严重性也与接种意愿相关，调整后的优势比分别为2.22（95%CI，1.44至3.41）和2.76（95%CI，1.87至4.09）。年龄和种族是预测疫苗接种率的仅有的独立人口统计学特征。
针对感知风险、感知易感性和疫苗犹豫的公共卫生策略可能有助于提高疫苗接种率。
