Summary: an (islandic?) epidemiologist is disappointed that vaccines have not lead to herd immunity yet, argues that we should accept infections of the vaccinated in the hope of reaching herd immunity that way. Proposes to give booster shots to people who received the less effective Janssen (Johnson&Johnson) vaccine and to vaccinate children because no serious vaccine side effects are known for children while delta variant could be dangerous for them.
All in all it sounds more reasonable than the title initially suggested. I still wouldn't upvote it because of the misleading title.
