Nevada expects to get 24,000 doses of the newly authorized Johnson & Johnson COVID-19 vaccine this week, but state officials have not yet detailed whether the single-shot vaccine will be targeted for use in any particular community. Candice McDaniel, health bureau chief of Nevada’s Bureau of Child, Family and Community Wellness, said the state will await guidance from the federal Advisory Committee on Immunization Practices before issuing recommendations for local health departments on the use of the one-shot vaccine.
