Vaccine means governments can allow greater number of daily cases before hospitals overwhelmed. Difficulty comes if exponential increase in cases leads to lockdown as hospitals become overwhelmed as horse has bolted at that point.
I work in frontline health care and it’s been noticeable how poor public discipline is becoming in some cases. I did a face to face routine review with someone yesterday who spent entire consultation coughing (wasn’t in about cough), when asked if they had done lateral flow or PCR they said “No, I can tell it’s not COVID as it just feels like a virus.“. They then explained how the fact they couldn’t taste or smell confirmed it wasn’t COVID as they sometimes get a cough, temp and loss of smell with colds. This person had been sat in waiting room around at-risk people, had a face to face with a front line health worker, and was half arsed about mask usage would often let mask ride up chin or nose would be outside mask. I wish this was an isolated case. In our county to get PCR done usually involves a drive outside of the county so many symptomatic people can’t be bothered to get checked, which makes local rate data increasingly unreliable.
If there is any further lockdown or more stringent measures it’ll be the Increasingly oblivious selfish, lazy parts of society that will have driven it. Genuinely fearful for prospects of a full season sadly at this point.
