Are you getting the same type booster that you got for your initial vaccination? I mixed mine and had some more side effects than I did for the first two.
Yes. My first two were Moderna and when I went in for the booster I asked for the Moderna, but they only had Pfizer. I asked if it was okay to mix them, and the pharmacist told me that was fine.
Garlic will tear my stomach up, but I can tolerate small amounts when cooking. My Dad made a white sauce loaded with garlic once and I was in agony for several hours.
