    Coronavirus Variants: Down to the Details

    It’s my impression that the pace of headlines and tweets, etc. about the many COVID-19 variants has increased recently (and it wasn’t exactly an unexplored topic before). Some of the coverage is just horse-race stuff (here comes this one, around the curve comes that one), but some of it is downright alarmist. And while I’m… Read More

    Antibody-Dependent Enhancement and the Coronavirus Vaccines

    I’m getting a lot of queries about antibody-dependent enhancement these days, and I can only assume that’s because there’s a lot of talk about this making the rounds of various social media platforms. Many of the people who are contacting me sound a lot more worried than I would have thought, so that prompts me… Read More

    Does Prior Exposure to Coronaviruses Protect You?

    There’s a new paper out that clears up some of our thinking about the current pandemic and what protection people might have had before the latest coronavirus showed up. As so many people know by now, there are a lot of coronaviruses running around out there, and they are responsible for a small-but-real fraction of… Read More

    How You Make an Adenovirus Vaccine

    The other day I had a look at the process used to make the mRNA vaccines, so I thought it would be a good idea to do the same for the adenovirus vector ones, such as J&J, Oxford/AstraZeneca, CanSino, Gamaleya et al. It’s a different system, with its own advantages and disadvantages, and that’s the… Read More

    Adenovirus-Vector Vaccine Roundup, Feb 5: Sputnik and More

    We’ve had yet more news in this area in the ten days or so since my last vaccine news roundup post, so here’s a look at the current situation. Most all the news has been in the viral vector area, so I’ll stick to that this time around. The big news here is the publication… Read More

    Oxford AstraZeneca Data, Again

    We have some more data to mull over with the Oxford/AstraZeneca vaccine. The situation so far has been pretty confused, with various efficacy numbers appearing from different people in different venues. It’s fair to say that the rollout of the clinical data has not gone smoothly, and that it’s done the effort no favors. As… Read More

    Myths of Vaccine Manufacturing

    In the last few days, the question of why more drug companies haven’t been enlisted for vaccine production has come up. It’s mostly due to this tweet: The problem is, as far as I can see, this is simply wrong. There are not “dozens of other pharma companies” who “stand ready” to produce these mRNA… Read More

    Screening, Within and Without

    So I’m a small-molecule drug discovery person at heart, since I started out as a synthetic organic chemist. Talking about vaccines and antibodies nonstop is a bit of a strain, then, because immunology is full of stuff that’s rather far removed from good ol’ small-molecule ligands. Actually immunology eventually wears out everyone. Read More

    J&J and Novavax Data

    Suddenly we have a lot more vaccine efficacy data to discuss! Yesterday came an announcement from Novavax about trials they’ve been conducting in the UK and in South Africa with their recombinant protein vaccine, and today comes equally anticipated data from J&J (Janssen) on their adenovirus vector candidate. We’ll have a look at th… Read More

    Vaccination Against the New Variants: Real-World Data

    We’re definitely not out of the pandemic woods yet, and neither is this blog – so let’s talk some more about antibodies today, in the hopes that we’re getting closer to the time when I (and all of us) can ignore immunology for a while. But we’re not ignoring it today! There’s a lot of… Read More
