It would be good to mount the seemingly insurmountable problems associated with making next-gen covid vaccines.

Looking beyond one or two covid infections - and looking at say 10 or 20 covid infections over the next 20 years, the question arises about what endemicity looks like? I just read 'SARS-CoV-2 and "Textbook" Immunity' on the JohnSnowProject website. One of the long-term endemicity models looked like this and I'd be interested to hear your view?

"At some point the [organ and immune system] damage accumulated, together with the accelerated immune system aging we discussed earlier plus normal aging processes, can reasonably be expected to outweigh the protective benefits of the memory B and T cells developed from previous infections. As a result, the baseline risk shifts higher - eventually much higher than what it would be at a given age for a first infection."

If true, it's worth trying to surmount the insurmountable.

always appreciate your efforts to disseminate important science that helps the lay public have at least an inkling of viral pathophysiology
