The caller confirms the details provided by the transferring agent, physician reports that his nurse vaccinated the patient with the full dose of the Covid 19 vaccine. The patient had a negative Covid 19 virus test today prior to receiving the Covid 19 vaccine. The doctor who saw the patient was able to convince him to get the Covid 19 vaccine. The nurse who drew up the Covid 19 vaccine from the vial didn't read how to draw it up.
