TWiV reviews a case of polio in Gaza, more Mpox, COVID-19 boosters, effectiveness of Ebola virus vaccine, measles cases across the US, an endogenous retroviral envelope protein that regulates human cardiomyocyte development, and submergence of…

The Team with Invincible Values discusses whether dogs or cats passively carry SARS-CoV-2 on hair and foot pads, maternal to fetal transfer of antibodies in infected or vaccinated pregnant women, and evidence that retroviruses infected cetaceans before and after they moved into the oceans.

The League of Extraordinary Virologists celebrate the eradication of wild poliovirus type 3, and consider the effectiveness of an influenza vaccine produced in insect cells, and how small RNAs are protecting the Koala germline from retroviral invasion.

Paul Bieniasz joins the TWiV team to talk about the co-option, millions of years ago, of an endogenous retrovirus envelope protein by hominid ancestors for host defense against viral infection.

Ted and Welkin inform the TWiV team how the evolution of ancient retroviruses can be inferred by their sequences in the genomes of modern mammals, and join in a discussion of virus dispersal during different methods for drying hands.
