The whole point of the vaccine is to reduce the severe effects of Covid i.e. death from said virus. It is also claimed to reduce the impact on the lungs and heart. One dose is slightly effective but two doses are better. So the statement about being admitted to ICU is an indication of not being vaccinated should have the word "probably" added to it. Even then its is no indication of how many doses the person has had. LB is correct in that the point of being vaccinated is to allow for society to be able to live with Covid and have the borders opened.
