    The Russian Vaccine Data

    An open letter has appeared about the recently published data from the vaccine development effort at Russia’s Gamaleya reseach center. This is of course the one that the government announced had been “approved” before even going through any Phase III trials, an even that I characterized at the time as a “ridiculous publicity… Read More

    Serious Adverse Event Time

    Lots of uncertainty in the vaccine world today: as many will have heard, the Oxford/AstraZeneca trial in the UK, the US, and Brazil has been paused due to a serious adverse event. The New York Times, citing a source with knowledge of the event, reported last night that this was transverse myelitis. And Nature has… Read More

    Bradykinin and the Coronavirus

    There’s a new paper that a lot of people are talking about recently that presents a rather large unifying hypothesis about the effects of the coronavirus (and suggests some new modes of treatment as well). This is the “bradykinin hypothesis”, and before digging into it, it might be worth a paragraph to talk about what… Read More

    Coronavirus Vaccine Roundup, Early September

    It’s been a while since I went through the whole vaccine landscape (I’ve been putting it off!), but there’s a lot to catch up on. I’m going to incorporate some slightly reworked material from my July post in the introduction to each vaccine class, for reference, but everything on the candidates themselves is updated informat… Read More

    Cold Chain (And Colder Chain) Distribution

    OK, it looks like we’re finally going to be talking about a vaccine logistics issue that many people (including me) have been worried about. Specifically, how are these things going to be transported and stored? If you’re not in the biomedical field, that question might seem a bit boring and bring up mental pictures of… Read More

    Thoughts On a New Coronavirus Test (And on Testing)

    Word came yesterday that Abbott received an Emergency Use Authorization for a new coronavirus test, one that is faster and cheaper than anything currently out there. The two types of tests that we see in use now are RT-PCR, the nasal-swab test that detects viral RNA, and various antibody tests, that tell you if you… Read More

    Preparing For the Vaccine Results

    So let’s take a few minutes to think about what happens when the vaccine trials start to read out. I’m making the assumption that the data will be freely available in a timely manner (which means before any decisions are made), because the alternative to that is Not Real Good. Another not-real-good alternative would be… Read More

    Encouraging News About Coronavirus Immunity

    We’ve had some good news on coronavirus immunity recently – good because it gives us some more clarity on the whole situation, and because it suggests that both people who have already recovered from the infection and people who will be getting vaccinated can have good protection. We have this preprint from several of the… Read More

    Nanobodies Against the Coronavirus: Something New

    So let’s talk about nanobodies – there’s a coronavirus connection to this, but it’s a good topic in general for several reasons. We begin at the beginning: what the heck is a “nanobody”? Antibody Structure The name is derived, rather loosely, from “antibody”. So let’s spend a minute on what anti… Read More

    The Russian Vaccine

    Many will have heard Russia’s announcement that they have approved a coronavirus vaccine. I’ve already had several people ask me what I think of it, so let me be clear: I think it’s a ridiculous publicity stunt. If it’s supposed to make Russia look like some sort of biotechnology powerhouse, then as far as I’m… Read More
