I think you need to work on your comprehension of statistics, being 5 times less likely to get something and 30 times less likely to be affected by it is not;
So you are safer, but not by much.
And this;
SInce the vast majority won't need it, soon it won't matter if the odd unvaxxed is in hospital. Isn't that the whole point of made up targets like 80% and 90%?
Most people obey the road rules, but our taxes and medicare as well as regos make us pay for those small minorities that don't. As has been said earlier the choice of this minority costs the tax payer a lot, every one in ICU is costing thousands per day. More minor cases are costing hundreds. As above being vaccinated removes a factor of 30 from the hospital system to being able to just sit at home.
Your so called "new" study is dated 15th January 2021, before mass vaccination had even become a thing. I suggest you read your information before using it in public argument.
