Hi Cactus Flower,
I had the Moderna. The pharmacist said to stick with the type you had.
Delta hit us hard because too many are careless & unvaccinated.
Another study indicates Moderna’s vaccine generates higher antibody levels than Pfizer’s
The findings indicate it might be because the Cambridge biotech’s dosage contains more messenger RNA.
