The patient received the Johnson & Johnson Covid19 vaccine on 30Jul2021, having decided on his own. Patient was looking for guidance on how to proceed moving forward, especially with "booster's being recommended". Patient wanted to know how protected he might be having gotten one dose of the Pfizer Covid19 vaccine and one dose of the Johnson & Johnson Covid19 vaccine?
