Got yourself all in a lather for nothing, the vaccine has existed since November of 2009, comparing today to the "common flu" is absurd, anyone can go to the local drugstore and get the vaccine, not possible for the coronavirus
While you are on the topic, the H1N1 was easier to treat than the coronavirus given that we had previous experienced similar influenza viruses, no one has experienced anything resembling the coronavirus, it is basically a highly contagious viral pneumonia, and, at when H1N1 did hit, a percentage of the population already having antibiotics in their bodies from prior similar virus, nothing close exists for the coronavirus. Circumstance today and in 2009 aren't automatically similar
