>Cellular immunity is highly durable and effective. The question is not how long the immunity lasts (based on original SARS patients, probably multiple decades to a lifetime), but whether affinity-matured T-cells can sufficiently cover the antigen-space of future ACE2-binding spike proteins. Somatic hypermutation might still be too complex to model computationally to answer that question outright. Do you know whether this question is answerable in another way?
