  I don't recall the exact figures, but I believe it wasn't spectacular. Moreover, now that Delta is a thing, aren't the ethical issues nonetheless present.

    From [0] > A recent study found that vaccinated people infected with the delta variant are 63 per cent less likely to infect people who are unvaccinated. [1] > This is only slightly lower than with the alpha variant, says Brechje de Gier at the National Institute for Public Health and the Environment in the Netherlands, who led the study. Her team had previously found that vaccinated people infected with alpha were 73 per cent less likely to infect unvaccinated people. [2] > What is important to realise, de Gier says, is that the full effect of vaccines on reducing transmission is even higher than 63 per cent, because most vaccinated people don’t become infected in the first place.

  delta completely out competed the original variant, but for the sake of due diligence it would be nice to see data on how effective the vaccine is against the original variant
