Yes, and in addition to that, the regimen of shots and boosters becomes too much for unvaccinated to contemplate. They are more being asked to enter into a new lifestyle, now, contrasted with the request a year ago to take one simple protective action.
In the US, I would like to see the recommendation change to a single Pfizer shot with second shot and booster language changed to that of optimization, rather than necessity. The single shot, even after several months, is still very effective against severe cases. I believe the vaccination rate would increase and that pressing to get our 1+ shot rate above 90% could be a genuine bipartisan rally.
