During 2013, isolation of a wild type 1 poliovirus from routine sewage sample in Israel, led to a national OPV campaign. During this period, there was a constant cover of the outbreak by the mass media.
To investigate the association of media exposure and OPV and non-OPV vaccines uptake during the 2013 silent polio outbreak in Israel.
We received data on daily immunization rates during the outbreak period from the Ministry of Health (MoH). We conducted a multivariable time trend analysis to assess the association between daily media exposure and vaccines uptake. Analysis was stratified by ethnicity and socio-economic status (SES).
During the MoH supplemental immunization activity, 138,799 OPV vaccines were given. There was a significant association between media exposure and OPV uptake, most prominent in a lag of 3-5 days from the exposure among Jews (R.R 1.79C.I 95% 1.32-2.41) and high SES subgroups (R.R 1.71C.I 95% 1.27-2.30). These subgroups also showed increased non-OPV uptake in a lag of 3-5 days from the media exposure, in all vaccines except for MMR. Lower SES and non-Jewish subgroups did not demonstrate the same association.
Our findings expand the understanding of public behaviour during outbreaks. The public response shows high variability within specific subgroups. These findings highlight the importance of tailored communication strategies for each subgroup.
2013 年，以色列从常规污水样本中分离出野生 1 型脊灰病毒，导致全国开展口服脊髓灰质炎疫苗（OPV）运动。在此期间，大众媒体持续报道此次疫情。
调查 2013 年以色列静悄悄的脊髓灰质炎疫情期间，媒体接触与 OPV 和非 OPV 疫苗接种之间的关系。
我们从卫生部（MoH）收到了疫情期间每日免疫接种率的数据。我们进行了多变量时间趋势分析，以评估每日媒体接触与疫苗接种之间的关联。分析按种族和社会经济地位（SES）分层。
在 MoH 补充免疫活动期间，共接种了 138799 剂 OPV 疫苗。媒体接触与 OPV 接种之间存在显著关联，在犹太人（RR 1.79，CI 95% 1.32-2.41）和 SES 较高亚组（RR 1.71，CI 95% 1.27-2.30）中，这种关联在接触后的 3-5 天最为明显。这些亚组在接触媒体后的 3-5 天内，除了 MMR 之外，所有疫苗的非 OPV 接种率也有所增加。SES 较低和非犹太人亚组则没有表现出同样的关联。
我们的研究结果扩展了对疫情期间公众行为的理解。公众的反应在特定亚组中表现出高度的可变性。这些发现强调了针对每个亚组制定量身定制的沟通策略的重要性。
