Once introduced into the human body, the protein-making machinery uses this genetic material in our cells to churn out the coronavirus “spike protein,” triggering an immuneresponse. Another consideration is that while in traditional vaccine development, clinicaltrials are carried out in sequence.
A trial of Russia’s Sputnik V coronavirus vaccine has shown the jab produces an immuneresponse, although the study was too small to produce conclusive findings, particularly on safety. All participants in the phase 2 trials (40 participants) produced antibodies against the SARS-CoV-2 spike protein.
Patients provide blood samples for clinicaltrial sponsors to develop and deliver these emerging immunotherapies. Flow cytometry (FCM) is the primary method scientists use to monitor immuneresponses in clinicaltrials, primarily because of its power, speed, and ability to provide a comprehensive view of a disease’s macro-environment.
