PSA: I just found out my house's original siding was installed without a vapor barrier

I was pulling off some old cedar clapboard on my 1978 ranch to replace a rotten section, and there was just bare sheathing behind it. No paper, no plastic, nothing. I looked it up in a building code history book from the library, and apparently that was common practice here in Ohio until the early 80s. Now I'm worried about moisture getting into the walls from the inside out. Has anyone else had to retrofit a vapor barrier during a re-siding job?

@kim_hart7 rawdogging the weather is a bold strategy.
