The COVID-19 pandemic has been ongoing for close to a year, with second waves occurring presently and many viewing vaccine uptake as the most likely way to curb successive waves and promote herd immunity. Reaching herd immunity status likely necessitates that children, as well as their parents, receive a vaccine targeting SARS-CoV-2. In this exploratory study, we investigated the demographic, experiential, and psychological factors associated with the anticipated likelihood and speed of having children receive a SARS-CoV-2 vaccine in a sample of 455 Canadian families (858 children; parents' mean age = 38.2 ± 6.82 years). Using linear mixed-effects and proportional odds logistic regression models, we demonstrated that older parental age, living in the Prairies (relative to Central Canada), more complete child vaccination history, and a greater tendency to prioritise the risks of the disease relative to the risks of side effects (i.e. lower omission bias) were associated with higher likelihoods of intention to vaccinate participants' children, with trend-level associations with lower perceived danger of the vaccine and higher psychological avoidance of the pandemic. Faster speed of intended vaccination was predicted by a similar constellation of variables with an additional predictor of a child in the family having a COVID-19 related health risk being associated with slower intended speed. Results are discussed concerning public health knowledge mobilisation and the unique Canadian health landscape.
新冠疫情已持续近一年，目前正出现第二波疫情，许多人将疫苗接种视为遏制后续疫情浪潮和促进群体免疫的最有可能的方式。要达到群体免疫状态，儿童及其父母可能都需要接种针对严重急性呼吸综合征冠状病毒2（SARS-CoV-2）的疫苗。在这项探索性研究中，我们调查了455个加拿大家庭（858名儿童；父母平均年龄 = 38.2 ± 6.82岁）样本中，与预期让孩子接种SARS-CoV-2疫苗的可能性和速度相关的人口统计学、经验和心理因素。使用线性混合效应模型和比例优势逻辑回归模型，我们发现父母年龄较大、居住在大草原地区（相对于加拿大中部）、孩子的疫苗接种史更完整，以及相对于副作用风险更倾向于优先考虑疾病风险（即较低的遗漏偏差），与让参与者的孩子接种疫苗的意愿较高相关，与较低的疫苗感知危险和较高的对疫情的心理回避存在趋势水平的关联。类似的一组变量预测了更快的预期接种速度，另外一个预测因素是家中有一名儿童存在与新冠病毒病相关的健康风险，这与较慢的预期接种速度相关。我们讨论了有关公共卫生知识传播以及加拿大独特的健康状况的结果。
