Well to be fair there's quite a bit of evidence that it prevents transmission and infections out there now.
It's preliminary data, thus cautious optimism is required. It will also vary by which vaccine people have had.
However every single person should still be following the rules for as long as necessary and that will for a few more months yet. At the very least. Social distancing will be in place for quite a while.
Current mask, distancing and hygiene measures need to be in place for a while to come. With the virus mutating there is a chance a new strain will appear that will reduce or negate the efficacy of vaccines. We are nowhere near out of the woods yet.
Unfortunately I think we'll see plenty of people of all age groups not caring much once they've been vaccinated
Of course some will, it's human nature. I've seen plenty of people saying they won't get vaccinated as they trust their immune systems over an untested vaccine. I've explained the basics of how mRNA vaccines work to people who don't understand even basic cell biology. What do I get in response ? Rants about genetic engineering.
Once we've done all the way down to the over 40s I dread to think what it'll be like in a supermarket.
I'll be avoiding supermarkets, unless it's really early in the day before they get rammed.
People need to realise that yes once we've done most of the population we'll likely be able to ditch social distancing but we need to make sure the numbers are low and will stay low before we ditch it totally.
We won't be able to ditch social distancing entirely for a while yet. Maybe once we get more advanced COVID-19 vaccines we will be able to. It will only take one COVID-19 variant that spreads rapidly to undo all the hardwork of Scientists and the NHS in getting the nation vaccinated. We will have a semblance of normality by the summer, but it won't be what people are hoping for.
I get the feeling that masks won't disappear in the long run, in so much that people who are sick might decide to wear them to avoid infecting people. Might not be a whole lot of people though.
