Caller stated that she tested having COVID around September using home testing kit but then recovered. Caller also mentioned that she shared some of the side effects she is experiencing to DSU before transferring her to MI and she thinks it is attributed to the Moderna bivalent vaccine which she recently received. Caller wants to know if mixing 2 different vaccine brands affect the effectiveness of the vaccine itself. Caller is calling because caller had a total of 3 shots of the Pfizer COVID-19 vaccine. Caller went to Withheld yesterday to receive caller's 4th shot, and the vaccine caller picked was the wrong vaccine. Caller should have picked the Pfizer bivalent COVID-19 vaccine but caller picked the Moderna COVID-19 vaccine, which caller later clarified in the call was the Moderna bivalent COVID-19 vaccine. Caller was focused on bivalent. Caller is wondering if mixing 2 different vaccines would that affect the effectiveness of the vaccine? Other question caller has is in regards to side effects. When caller had the Pfizer COVID-19 vaccine caller did not have as strong of a reaction as caller is having now so caller wants to make sure this is normal since caller mixed the vaccines? Caller received the Moderna COVID-19 vaccine, which caller clarified and confirmed was the Moderna bivalent COVID-19 vaccine, yesterday, 22Sep2022.
