The problem is people will have the vaccine and think I’m safe and off they go about their normal life but really its run out after x amount of time and they are vulnerable and could carrying the virus and passing it on .
You can say that about anything, such as norovirus, flu, etc. Covid will never be eradicated. It's ALL about keeping the infection rates low and controlling outbreaks. That's exactly why norovirus keeps spreading through hospital wards, all inclusive hotels and cruise ships. It's basically luck of the draw whether it's spreading at the same time you're in one of those places.
Vulnerable people make their own choices and take their own precautions. My OH has seriously impaired immunity due to cancer. A couple of years ago, we went on a cruise. We wiped down all surfaces in our cabin with anti-bac and never had the cleaners/steward in the cabin at all, so we kept it "sterile" to our standards. We avoided any busy areas of the ship - went to the quieter time shows, avoided the breakfast buffet herds of people, and were constantly washing our hands (we carried our hand gels with us). We basically did everything reasonably possible to avoid catching norovirus (or anything similar), balanced by actually wanting to have a cruise. That's the reality of people with compromised immunity systems - everything you do is a risk and you learn to mitigate that by taking more precautions.
After covid, hopefully it will be "the norm" for most people (at risk or not) to maintain pretty simple/basic hygiene standards such as regular hand washing, respecting personal space, catching coughs/sneezes in tissues, etc. It's a shame we needed a pandemic to highlight the importance of basics like that. And a bigger shame if people go back to their old unhygienic ways.
