ISLAMABAD: As the Covid-19 pandemic has disrupted life for many, including children in need of routine immunizations, Unicef Pakistan and Facebook have launched a campaign to promote life-saving immunization. In countries like Pakistan, additional roadblocks as a result of the pandemic have been compounded by an existing hesitancy in some communities to vaccinate children as well as global disruptions to the delivery of immunizations. For this reason, Facebook’s Data for Good team recently worked in partnership with the United Nations Children’s Fund (Unicef) to better understand constraints to vaccine adoption in Pakistan with the objective to help the development sector have better insights for effective, local outreach.
