Yes, 184 years but, in 1967, The World Health Organization launched the Intensified Smallpox Eradication Program and in 1980 it was declared to be eradicated.
So 13 years of intense diligence in administering a vaccine to all eradicated this disease
Glad there weren't online vaccine "experts" on the internet for those 13 years.
Seasonal influenza has not been eradicated but the lock downs has made it virtually non-existant.
No wonder you are so confused about vaccines - you don't even know that influenza and covid-19 are different viruses with different genetic makeups.
Probably wouldn't need boosters if everyone got the vaccine.
