COVID-19 Vaccine Distribution Physical Security Measures
Organizations involved in the development and distribution of the COVID-19 vaccine should take proactive measures to enhance their overall physical security posture. To achieve secure and resilient vaccine distribution, workers within the supply chain and vaccine recipients should use available resources to assess suggested mitigation methods against physical security attacks. To help meet this need, CISA created the COVID-19 Vaccine Distribution Physical Security Measures infographic. This product provides a list of physical security resources available to the public to help facility owners and operators enhance physical security to protect workers and individuals.
