    Merck Keeps Plowing On

    I last wrote about the small-molecule antiviral molnupiravir here, and we finally have more information from Merck and Ridgeback about its effects in clinical trials. An interim analysis of the Phase II data from trials in both outpatients and in hospitalized coronavirus patients has been completed, and the news is. . .mixed. In the outpatient… Read More

    Vaccine Side Effects Q and A

    So what’s the side effect that caused the J&J vaccine pause? Blood clotting – but not the usual kind. This appears to be the same (or very similar) to the problem seem with the Oxford/AstraZeneca vaccine in Europe, and both are very similar to a known syndrome called heparin-induced thrombocytopenia. That involves unusual binding to… Read More

    Vaccine Efficacy Questions

    Next up on the vaccine news front are some concerns about efficacy. In a very surprising statement, Gao Fu (the head of the Chinese Center for Disease Control and Prevention) said at a conference in Chengdu over the weekend that that the protection figures of the Chinese vaccines are “not high”. He called for research… Read More

    AZ/Oxford Calculations

    Update: the FDA has now paused use of the J&J vaccine due to 6 incidents of what appears to be VITT.  We have a lot of vaccine news to catch up on! First up is the latest on the possible clotting side effects seen with Oxford/AstraZeneca. This is looking more and more likely to be… Read More

    Vaccine Manufacturing Woes at Emergent

    The New York Times has a good story on the problems at the Emergent vaccine plant in Baltimore, following up on this one. They’ve uncovered a report from last summer that warned that the facility had quality control problems: A copy of the official’s assessment, obtained by The New York Times, cited “key risks” in… Read More

    Getting Vaccinated

    So as I mentioned on Twitter yesterday, I’ve now had my first coronavirus vaccine dose (Pfizer/BioNTech). Since I’ve been writing about the mRNA vaccines for months here and cheering on the vaccine efforts in general, I can tell you that I’m very, very happy to be able to follow through and actually take one. So… Read More

    Blood Clots and the AZ Vaccine, Revisited

    Once again, what’s going on with vascular events and the AZ/Oxford vaccine? I last wrote about this situation a couple of weeks ago, and it’s taken some real turns since then. At that point several EU countries had suspended dosing, but over the next week several began administering the vaccine again after the European Medicines… Read More

    AstraZeneca’s US Vaccine Trial Data

    Update: this has turned into a stupid, needless, mess. Which frankly seems to be AstraZeneca’s pandemic brand so far. It turns out that the company’s press release (as discussed below) is apparently more of an interim read than reflective of the final data. The NIH took the extraordinary step of stating its concerns about this… Read More

    The Problem with COVID-19 Clinical Trials

    Let’s talk about a painful subject. I am of the opinion – and I’m far from alone – that the most reliable way to determine if a possible therapy has any usefulness is a randomized, double-blinded controlled clinical trial. I can be a bit more specific than that, even: let’s make that “a trial that… Read More

    What is Going on With the AstraZeneca/Oxford Vaccine?

    Update: more on this in a later post here. Everyone will have heard of the situation in Europe right now, with a whole list of countries suspending dosing of the AstraZeneca/Oxford vaccine. Sweden and Latvia joined that list today .But getting clarity on this is another thing entirely. I have not been the biggest fan… Read More
