Past influenza pandemic information is available from many international (non-CDC) sources:

Nope, don’t believe my government “lock, stock and barrel”...they have various agendas and “influencers”/lobbyists. I analyze on a case-by-case basis. For example Fauci has worn out his welcome (his 15 minutes expired long ago) along with Powell and The Fed. I also base my outlook on 1st hand experience...20+ friends fully vaxxed (about 1/2 of those now “boosted” including my 83 y/o mother....no side-effects reported except for the usual sore arm, etc.. Also 2 acquaintances died from COVID-19 before the vaxx’s came out. Personally not vaxxed due to my wife & I being low-exposure/retired/rural (and I monitor my county’s “case count”...been very low for months)...may consider the Novavax product in the future. (Hopefully tweaked for Delta and the “B.1.1.529”/”Nu””Pres. Xi”/”Omicron” variant. Although the usual “virus MO” is mutations may yield a more infectious version but they are usually less serious and cause less hospitalization...like the “Pres. Xi” (WHO can’t be trusted fully either..it defers to CCP Xi)/”Nu”/”Omicron” variant is looking like so far.
Some other 1st hand experiences to round out a view....
That you trust a speedily “tweaked” vaccine suggests that our disagreement is about speed in the development of vaccines and other drugs. That seems the divide.
Given the history of drug development (especially vaccines) I am much more skeptical than you. That seems clear. Best wishes.
