Flu: Approved in 1945 for non-mil use after ~15 yrs of dev
Anthrax: Russia created in 1930, US in 1950s, current version created in 1960s after decades of dev
Malaria: First version in 1830, current day developed in 1970s
Covid: Dev’d in 6-11 months (depending on country), without traditional rigors of testing met
3/4 of the ones you mentioned have been dev’d, tested, and refined over an average of 41 years before anyone in the mil currently received them. One of the above was extremely rushed to say the least, shoved down millions of throats with unknown/TBD short and long term effects. Simultaneously, data at the time already demo’d people under 50ish who were generally healthy were as a whole generally not affected by COVID in any meaningful way. This of course has been double stamped, and now triple stamped (can you do that!?), proven by today.
So, there was no reason to resist the 40+ year vaccines/pills, where as there were/are objective reasons to resist a COVID vaccine, neither of which have any link to politics whatsoever. Then of course one can easily throw in all the questionable shit the gov and big pharma did, but that’s outside the scope of this specific response.
None of this is to say people who did wish to get the vaccine are bad or idiots or whatever. You do you based on your own assessment and in conjunction with your doc’s rec if you value that. Forced vaccine was reckless, even in the mil.
