Vaccines could be cool to give to entire populations, or for really poor or hard to reach places, doing a one and done approach. It could be part of kids’ shot regiment that they don’t even think about, like the hpv vaccine now.

Then for moderate and high risk people they could do the twice yearly shot once it becomes relevant.

I’m no expert in this field at all, just doing my armchair analysis here.
