Pfizer, Moderna

And, as always, everyone's forgotten that poor NovaVax exists.

Being serious for a moment: NovaVax is made in the "traditional" away vaccines have been made, which is good if you know someone who's anti mRNA vaccines. It has less and less severe side effects than Pfizer or Moderna. It's not quite as effective as the mRNA vaccines - but it tends to last a bit longer as well. It provides a different 'template' for recognizing covid, so it broadens your protection in that way.

One drawback is that if you want NovaVax in the spring, you need to get it early, as the batches tend to expire around April. (I time my shots for mid-May [max summer protection] and mid-to-late October [max winter protection].) I think I've had 3 Modernas, 4 Pfizers, and 4 NovaVaxs to date ...
