Highlights
:: In Summer 2013 poliovirus was detected in Israel’s sewage system. In response, a nation-wide immunization campaign was launched.
:: We analyzed Internet search statistics by district for polio-related terms for the time period of this campaign.
:: We compared Internet search statistics with official reporting obtained from the MOH.
:: Internet searches were highly correlated with same district MOH reported vaccination rates (R = 0.786).
:: These findings suggest a novel method for monitoring vaccination campaigns
