  • It was great, but it devolves into politics

    Please, show less political anger and emphasize more science. Don't turn into just another partisan show. Focus on convincing rather than scolding.

  • Fantastically informative podcast

    Huge thanks to Vincent and the team and guests who put so much effort into this platform! I learn so much and find the discussion engaging. I’m a microbiologist, trained as a bacterial specialist, but for nearly 2 decades I’ve been doing bacteriophage research and that’s my team’s focus (so I guess I’m a viral guy too now). I have learned a great deal from this podcast and have been led to some super-informative papers by it. Gargantuan kudos for the way the podcast addressed the COVID-19 p... more

Talking Points

Recent interactions between the hosts and their guests.

TWiV 1338: Clinical update with Dr. Daniel Griffin
Q: Mary also asks about the effectiveness of Paxlovid versus Zocova for treatment and how these compare to FDA-established data.
Paxlovid has strong FDA-supported data for treatment in eligible patients, whereas Zocova lacks equivalent US FDA-approved treatment data; in practice, Paxlovid is preferred for treatment when infection is confirmed.
TWiV 1338: Clinical update with Dr. Daniel Griffin
Q: Mary asks about whether testing for COVID should be required before starting Zocova for post-exposure prophylaxis and how to manage if symptoms develop.
The host explains that Zocova is used for prevention and that Paxlovid remains the treatment option for diagnosed COVID-19; testing may occur to confirm infection status, but the recommended pathway depends on the clinical scenario and regulatory indications.
TWiV 1340: Clinical update with Dr. Daniel Griffin
Q: So Vincent, is it fair to think of this as oral remdesivir?
The drugs are precursors to the same active polymerase inhibitor; remdesivir is IV with a prodrug that aids cellular entry, while obeldesivir is oral and activated differently, but the end target—RdRP inhibition—is similar.
TWiV 1340: Clinical update with Dr. Daniel Griffin
Q: David writes, interested in your thoughts on how the Legionella outbreak is being handled in New York City.
The response has been fairly rapid, with many towers cleaned within 48 hours, and there's ongoing discussion about using genetic sequencing to link cases to specific sources, though cost and scale remain considerations.
TWiV 1342: Clinical update with Dr. Daniel Griffin
Q: For someone worried about shingles and immunity, is prior infection protection reliable, and should they still get Shingrix?
Prior shingles infections do not guarantee lasting immunity; vaccination with Shingrix is recommended for protection, especially for adults aged 50 and over, to reduce recurrence risk.
