TL:DR: u/Anither claims a study is about vaccines when it isn't, references a second study that was withdrawn by 3 of its 4 authors, and provides 1) nothing relevant to covid virus transmission or 2) proof that Hydroxychloroquine is approved for use in treating covid.
Because the shots were never tested to reduce transmission
But they reduced transmission. For example: "A study of covid-19 transmission within English households using data gathered in early 2021 found that even a single dose of a covid-19 vaccine reduced the likelihood of household transmission by 40-50%" The British Medical Journal

The first vaccine was approved long after that study was concluded. It had nothing to do with vaccines.
The paper was voluntarily withdrawn by three of the four authors themselves. Read all about it here: https://retractionwatch.com/2020/06/04/lancet-retracts-controversial-hydroxychloroquine-study/.
Hydroxychloroquine is still not approved for use in treating covid.
