Absolutely. I do know that our next door neighbours brother in his forties had Covid in Wave 1, as a Qantas baggage handler, and he was ill wth an extremely high temp, headache like no other, and diarrhoea for about five days. His baggage handler friend of the same age ended up in hospital.
However, Sutton, when asked what freedoms the vaccination might bring, he was extremely cagey that restrictions would continue for a long time yet. This freedom from snap closure of state borders, and OS travel, initially to just see close family, is certainly my key driver too.
