In October 2023, following outbreaks in sea lions, the study authors surveyed a breeding colony of elephant seals at Punta Delgada along the coast of Península Valdés, Argentina. They recorded unprecedented mass mortality — some 17,000 elephant seals were dead. By November, 96% of pups born that season would die. Test results confirmed that HPAI H5N1 was present in the seals as well as in several terns that died at the same time.
The virus’ separation into avian and marine mammal clades unfolded as H5N1 clade 2.3.4.4b — specifically genotype B3.2 — arrived on the continent through migratory birds before spilling over to mammals. It then separated from the avian clade virus to become its own, marine mammal-adapted virus. Concerningly, while the virus moves across pinnipeds, it can also still infect birds. That was evident in the study, where the virus found in terns was identical to that from elephant seals.
“We’re showing the evolution of this marine mammal virus over time,” said virologist and co-leading author Agustina Rimondi of INTA. “This virus is capable of adapting to mammals, as we can see from the mutations that are consistently found in the viruses belonging to the mammalian clade.”

is a real concern
Meanwhile, in a scramble, billions of dollars are being spent on alternate
ways to manufacture vaccines that might be used in the event of a bird
flu outbreak in humans and with the scenario that with hens wiped out,
there may not be enough fertilized chicken eggs for vaccine production :-
