Since the outbreak of the global epidemic, the federal government has been carrying out the Warp Action external icon program, hoping to provide one or more COVID-19 vaccines as soon as possible. Although CDC is not involved in the development of the COVID-19 vaccine, it has been working closely with the health department and partners to develop an immunization plan for future vaccines. CDC is working with partners at all levels, including health care associations, to develop flexible COVID-19 immunization plans that can be applied to different vaccines and situations.
