The researchers also have access to rapid HBsAg tests which they will use on 200 women in the study, per the protocol from January. This means they could test for HepB in mothers before they randomize to this open-label trial. But they are not doing that.

Had Claude make me a chimeric antigen receptor a few months ago: it understood the basic design of the protein but the amino acid sequences it came up with were wrong in some weird/funny ways. Pretty sure that version could never make a biological weapon at least.

It wasn’t a non-starter back in 2014 when I studied in the UK, but I guess that’s a long time ago

LNP/mRNA methods are interesting outside vaccines in the context of cancer therapies. For example to deliver CAR therapy. Much of this work is very heavily leaning on work from the vaccine field, and shutting down this research has huge implications here (as well).

Unless you’re gunning for a 1.6 million grant, I don’t think a lot of Danish doctors feel that way.

It's the 3rd of January 1939, your name is professor James Smith and you are staring at a drawing of a fish. It's not a regular fish. It is a completely impossible fish.

But the rapport is not from the Danish authorities: it's written as part of a research-training course doctor take during their speciality training as general practitioners. Note the front page says: "Research training assignment 2018" and "Group 38".

I am not sure the presentation by Tracy Høeg necessarily reflect the true situation in Denmark. For example, her discussion about varicella zoster vaccine highlights a rapport written by non-experts, and present it as if, it is from the Danish authorities.

It’s definitely true that preexisting immunity affects transmissibility; but I think the virus adapted for increased transmission in humans as well, eg the D614G mutation and increased binding to ACE receptor found in some variants. Really I think you to look at protein level, not the variant name

Question is whether previous infections / vaccinations decreases this risk today. I am not saying I would risk it, but I am not sure the risk today is the same as in 2022 as most people have had multiple immunization events at this point

Additionally, certain types of autoimmunity also seem to react less strongely to the Zostavax vaccine. E.g. SLE patients generate a lesser T cell response (pmc.ncbi.nlm.nih.gov/articles/PMC...). But really there does not seem to be much data around on this? 3/3

How certain are you that this is actually the case? I am asking because many autoimmune patients are presumably taking drugs that affect a vaccine-response negatively (B-celle depleting drugs, DMARDS, ect). Also, I assume many autoimmune patients are not allowed to use live-vaccines? 2/3

Congratulations on a very interesting and important paper. In your discussion concerning the mechanism, you examine VZV-independent effects. You have a section on autoimmunity, which sort of hinges on whether the vaccine elicits the same response in autoimmune patients as healthy individuals. 1/3

If we’re in the range of say 10.000 other solar systems - and they need to spend a few million year evolving into something that cares / is able to look/send signals, perhaps the numbers don’t stack up so high as Fermi predicted? 2/2

If we imagine other species have the same tech we currently have: how many solar-systems could realistically have spotted us or received radio-waves from earth? I guess my point is, isn’t the period in which we have made noise/generated a bio-signatur too small for that many systems to spot us? 1/2
