Pharmacist advised us if one gets Moderna then get the Moderna booster. It is all on the person's account when the pharmacist looks up the info after one showing their CDC card. I like the fact that the pharmacist to ensure that the 15 min observation time is followed post vaccine shot that the pharmacist returns your CDC card after the 15 min egg timer goes off.I'd be curious to know if I have to get a booster, could I get Moderna or J&J? I originally had Pfizer.
