Purpose: This article intends to answer whether unit medical personnel, in order to eliminate viral spread, should recommend forming cohorts manned exclusively by personnel who have recovered from Covid 19 and are presumed immune. The intended audience is unit commanders and supervisors whose billet or position charges them with rostering aircrew personnel.

Method: The paper's author conducted a PubMed and MEDLINE literature search using a combination of the terms, acquired immunity, post-infection immunity, COVID-19, SARS-CoV-2, and vaccine. Thirty articles were selected and used to formulate this paper's clinical recommendations.

Results: The literature review did not support recommendations to form aircrew cohorts composed solely of personnel who have recovered from COVID-19 to reduce contagion.

Conclusion: The author bases the recommendation of not forming aircrew cohorts based solely on COVID 19 status due to the lack of evidence in the current literature regarding the veracity of acquired immunity post-Covid 19 recovery. As researchers produce and publish new studies, ongoing research will be the basis for updating this recommendation.
