Living with this Virus27 Feb 2021 23:47
The position in France is actually quite concerning.
I discussed earlier in the week the Horizon program regarding when we will get back to anything resembling normality and basically its proven that the answer is in a formula:
H = I – I/R over E
Put simply; Herd immunity, this being the percentage of people vaccinated in the population plus those with antibodies required to stop it spreading to regain control.
R reproduction number as we know is how quick it reproduces (1 in 3 is the natural level) but a new variant can see that increase to 4.5 or more which is the concern that can affect our current timelines. Then comes vaccine efficacy, how well the vaccine is working.
Now taking the expected AZK efficacy rates they state it would mean that 84% of the UK population would need to be vaccinated to allow herd immunity by November in the UK this year for a return to normality.
BUT a small percentage reduction in efficacy, such as the vaccine not working as well over the next year as expected OR worse new variants coming in rendering it less effective means the percentage of people vaccinated needs to go up even higher. For example, a new variant that spreads quicker and reduces efficacy by just 2% will see our vaccine required rate go up to 97% for herd immunity which is just not likely.
In the UK we have pockets of high virus spread and that is in lockdown so it could get worse as lockdown is lifted but, some areas will for whatever reason, race, religion, belief will not have as high vaccine take up percentages.
So, the conclusion being that we will need to adjust to living with this virus. We can live with the virus without herd immunity, but we need ideally vaccine rates as high as possible and we would need to continually test to keep on top of it and as I keep saying there will be a percentage figure of deaths a year that the government will consider as collateral damage and acceptable that we can live with. I.e., Flu kills 30,000 in a bad year, what would be OK level with Covid?
Finally, we turn to France, if the French are that stupid NOT to trust a vaccine and the take up rate Is that low as stated then the situation there is going to continue even longer not to mention we better sort out rock solid border control with PCR otherwise more will come here straight from France.
It is a bloody mess frankly…
