Yeah, very reasonable. It's unclear to me if B.1.1.7 might also have an "immunity" phenotype - a lot is said about the RSA variant in that regard, but that's because we have _data_ on E484K, but for B.1.1.7 we don't have anything yet. Also, Eeek is already in B.1.1.7 as you say....

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

    Indeed -here's one of many Hugo vs Doug (Genome copies not Ct) ~1 log whereas Nelly vs Doug is ~2 Logs on average it seems: [shared file(s): image.png]

    This is just the URT (nasal) I think data in the lung not as dramatic if any change at all (need lung data for Nelly, Eeek and Pooh) - worth noting Doug alone is easier to neutralize.

    My prediction is that B.1.1.7 will turn out to be more transmissible because of the 501Y with the other stuff (FCS, deletions etc) - and it arose because of an extraordinary circumstances. But the Brazilian and RSA variants will turn out to be doing well because they are fitter in the very high (and underestimated) existing seroprevalence in those places. So they will pop up every where but are unlikely to really take off in places with lower seroprevalence (or atleast no more likely than anything else).

    But that means they will soon be fitter in other places like USA and Europe unless things improve quickly.

    Oh, and to the last part - things over here won't improve quickly, unfortunately. It's rapidly deteriorating - without the effect of the new lineages.

    Students are coming back to Tulane campus - there is an almost desperate attempt to get one of the vaccine manufacturers to vaccinate all or at least part of the undergraduate students for the purposes of doing an vaccine efficacy study. It'ds almost as good as a challenge trial because the undergrads will be tested 2-3 times per week.So far pushback, because corporate think. I don't think they want to know or are afraid to even raise the question hence the Nelly study above. Most of the medical faculty and some of the med students and residents have already gotten the first doses. Faculty, staff, med students, residents and grad students are getting the Pfizer vaccine next week.

    Eddie, you don't look too happy at the prospect of lunch, I think:
