It's rather more direct than that. The Covid vaccine doesn't help that much in reducing transmission because it is not a sterilising vaccine. Hence we have rather more cases than we would like in countries where vaccination rates are in the high 80%s. So it is like giving boys an HPV vaccine that isn't that likely to stop them giving girls cervical cancer, but pretending to them that it does. With the knock on to behaviour patterns that belief may have. We are rapidly moving into the area of diminishing returns with Covid that cannot be avoided without better vaccines.
