Not sure what the comparison with COVID is supposed to be. Spanish flu was not created in a lab. There was no vaccine for the Spanish flu. The only real similarity is social distancing, quarantines, and masks -- we did that back then too.
This seems vague. Can you elaborate on the claim you’re making?
Neither was covid-19: https://www.science.org/doi/10.1126/science.abp8715

The article literally says there is no consensus.
From further in the article: "But the once controversial theory has been gaining ground among some intelligence agencies - and the BND is the latest to entertain the theory. In January, the US CIA said the coronavirus was "more likely" to have leaked from a lab than to have come from animals."
Clearly world leaders were afraid of anti-Chinese sentiment, didn't want to be seen "siding" with Trump, or just didn't want to piss China off.
2. The lab leak hypothesis is geopolitically convenient for the US
3. They explicitly state "low confidence" in their affirmation of this hypothesis
2. Irrelevent because:
3. Low confidence, but probable merely implies plausibility, at least a somewhat higher likelihood than a wild previously unencountered zoonotic.
Based on all publicly available information it does seem more likely, the CIA will be better informed than the public, if they (and others) concur then I don't see why we need to dismiss it.
