Children under the age of 5, will likely all be offered vaccination against SARS-CoV-2 soon. Parental concerns over vaccination of children are long standing and could impede the success of a vaccination campaign. In the UK, a trusted source to inform vaccination choices is the NHS website. Here we used a randomized controlled experiment of framing effects in NHS information content for COVID-19 and flu with 550 mothers under the age of 5. We compared both vaccination offers following two commonly used frames in vaccination informational campaigns: alerting to the risks of no vaccination for the child itself vs. those in their community. We find that vaccination intention was twice as high when risks to the child are emphasized, relative to risks to the community. Exploratory analyses suggest that these effects may differ between white and non-white mothers. Whilst communication directed at adult vaccination against COVID-19 generally focuses on risks of infecting others, communication about vaccination of children may benefit from emphasizing risks to the children themselves. This pattern is in line with flu vaccination research from pre-COVID-19 times.
5岁以下的儿童可能很快都将接种新冠病毒疫苗。家长们长期以来一直对儿童接种疫苗存在担忧，这可能会阻碍疫苗接种运动的成功。在英国，国民保健署（NHS）网站是提供疫苗接种选择信息的可靠来源。在此，我们对550名5岁以下儿童的母亲进行了一项随机对照实验，研究新冠病毒和流感疫苗接种信息在NHS内容中的框架效应。我们比较了疫苗接种宣传活动中两种常用框架下的疫苗接种提议：提醒未接种疫苗对孩子自身的风险与对其所在社区其他人的风险。我们发现，相对于对社区的风险，当强调对孩子的风险时，接种意愿高出两倍。探索性分析表明，白人和非白人母亲的这种效应可能有所不同。虽然针对成年人接种新冠病毒疫苗的宣传通常侧重于感染他人的风险，但关于儿童接种疫苗的宣传可能会因强调对儿童自身的风险而受益。这种模式与新冠疫情之前的流感疫苗接种研究一致。
