Yes there will probably be a second (or third) wave.
BUT assuming having had it previously provides immunity for a year or so:
Lots of frontline staff will have had it, so hopefully that slows spread through hospitals etc.
There is a treatment (steroids) which are cheap, generic and widely available which prevents approx 1/3 of deaths.
Lots of suggestion that the virus is mutating and is less deadly than it was (fingers crossed)
And... sadly, a lot of those vulnerable to the virus have already died. Hopefully meaning care homes won't get hit so hard. As they have already been hit hard and it ran rampant through the care homes.
Schools returning will cause blips but as long as we can access testing then local lockdowns should help stem the flow.
I suspect masks will become compulsory when in shops. Which will help a little
But the virus apparently thrives at approx 4 degrees C. So if we have a cold winter that will make it worse.,
I wonder if they'll reintroduce the BCG vaccination alongside the flu vaccine this year for the vulnerable. I think I read an article that said that it helps with covid.
