Can we forecast the next clade?
Models help; surprises still appear, so surveillance remains the backbone.
A shot that does not need annual updates is a long research aim aimed at conserved HA parts.
Watching bird and swine subtypes is surveillance, not a home experiment.
Open questions
What would a universal shot need?
Broader, durable responses to conserved antigens — still in trials and concepts.
How dangerous are current avian subtypes for people?
Some cause severe disease but spread poorly between people so far. Risk is watched, not a score for panic.
Did COVID change flu forever?
A few seasons were odd. The virus did not retire; calendars are resettling.
How do we talk without villains?
Name measured traits: spread, severity, vaccine match — not super-flu adjectives.
The frontier is maps and vaccines, not construction.
