While, I respect Hoyle's theories as well thought out (though
going against the conventional wisdom) and am mildly optimistic
about the possibility of microorganisms or their precursors
arriving from space (panspermia), I have to draw the line
at blaming the flu on this.
Variances in the flu (influenza) are quite adequately explained
by the multi-part genome that recombines with different strains
from ducks or pigs in farm settings producing new, more virulent
strains every few years. This is simple genetics. Spores from
outer space are not required!

True, but the major flaw is the lack of energy concentrations
to drive chemical reactions. This is life in a very slow lane.
Much better is that space serves as a stasis environment until
the next fertile location is encountered.
