As I understand it…the northern and southern hemisphere depend on each other in determining which strain to include in the vaccine. So the north looks at what has happened in the south to determine what to include in the north for the next season right? So I wonder…why do this? Why not just include all 14 of the known strains and be done with it? Is there an incompatibility that we don’t know about? Asking for a friend…





…but if it works…I mean…you can milk a cat.
