    Annual isn’t enough.

    Pooled estimates of VE of a primary vaccination cycle against laboratory-confirmed Omicron infection and symptomatic disease were both lower than 20% at 6 months from last dose administration. Booster doses restored VE to levels comparable to those acquired soon after the administration of the primary cycle. However, 9 months after booster administration, VE against Omicron was lower than 30% against laboratory-confirmed infection and symptomatic disease.

      Oh, yeah, I meant to type “at least” annual. Apparently, my brain thinking about typing that was enough.

      There’s some early evidence that more traditional vaccines (like NovaVax) may create longer protection than the mRNA vaccines (which seem to have more robust but shorter-lasting protectection).
