> If we’re going to disingenuously compare smallpox and measles vaccines, perhaps we could start with their efficacy. Are there any claims from even the mfgs that Covid shots are in the same range?

Ain't nothing disingenuous from me. The COVID vaccines are some of the most effective vaccines ever invented.

Turns out, if you were the only vaccinated person in a house against smallpox, the efficacy was only 60-something percent. But vaccination also prevents you spreading to others, not just getting infected—so when everybody in a house was vaccinated, the efficacy rose to around 95%.

That's not unlike the COVID vaccines.

I didn’t know that. Do you have a source that shows efficacy over 45% after 8 months? I couldn’t find one.

That's an oddly specific ask. The vaccines are absolutely fantastic in the short term, and there's credible evidence indicating the vaccine protection is long term, by analogy with how other vaccines work.

See e.g. https://twitter.com/sailorrooscout/status/141602012829108224... and https://www.thelancet.com/journals/lancet/article/PIIS0140-6...

Also worth noting, see scary stories about vaccine efficacy dropping (coinciding with alpha being replaced by delta)? Turns out the efficacy recovers afterwards. See https://twitter.com/sailorrooscout/status/143849966572136858.... Other real world studies show robust protection in the medium term, see https://twitter.com/sailorrooscout/status/143995133263551692....

The efficacy is “recovering” because the vaccinated are acquiring natural immunity. The way you / sailorrooscout present it obscures that simple fact.

That's not a simple fact; that's something you're making up.
