Hi,
I'm watching the Coronavirus briefing and I can't believe what I'm hearing!
Boris was saying that we saw what happened with other countries, we haven't been far behind in terms of a second wave, we've seen this before etc, as though we all know where this is heading, I.e, a 3rd wave!
He's talking as though this is inevitable! Have I missed something? Have vaccines been announced as useless?
These countries that he's talking about, the ones which we have always "followed in the past", don't have a vaccination programme like ours, so why is he speaking like this?
I feel really angry. He will have scared a lot of people talking like this.
Firstly a 3rd wave is likely. If R goes over 1 and we don't tighten restrictions again, then it is inevitable. Vaccinations help reduce R, but reducing lockdown measures raises it - who will win that race??
Secondly, lots of people think it doesn't matter if R goes over 1 because "the vulnerable are protected". This is horse shit. If that was true, we may as well end lockdown tomorrow because everyone over 60 who wants a vaccine has had one. What would the consequences be though?
Well the % vaccinated is much too low to prevent the virus infecting everyone and it would do so within a matter of 2-3 months. Obv not EVERYONE would catch it, but data from elsewhere suggests you could get around 75% infected within that period.
Let's assume vaccination gives 90% protection. There's 5.6 million aged 70-80 in the UK and 3.2 million >80. If 75% of them get the virus that's 6.6 million cases.
The death rate (unvaccinated) is 2.2 to 3.6% for >70's and 5.3 to 8.9% for the over 80's - I'll take the median of those figures. Works out as 389,600 deaths. Add in the impact of the vaccines, i.e. reduce by 90% and you have nearly 40k deaths which is about 4x as many as die from flu in a typical year.
That's just among the >70's, assumes they're ALL vaccinated (they're not) and assumes the vaccine efficacy remains at 90% as mutations arise (it won't).
Then let's consider the 10-20 yr age group who are going to be largely unvaccinated until 2022. Covid barely effects them right? Sort of - IFR is about 0.02%. If 75% get infected it translates into 1110 deaths.
So far we've only let a fraction of the population catch covid - it's been controlled through lockdown and social distancing measures. If we abandon those before the virus has been stamped out, the benefits of the vaccine are far outweighed by the sheer numbers of infections involved.
And I haven't even mentioned long covid - we don't know if vaccines prevent this or not yet - seems likely but even assuming we have 60% vaccine coverage and a 90% protection level we could be looking at well over a million cases of it in the event of a 3rd wave we don't bother trying to control.
Vaccines give us the ability to keep R below 1 and build up herd-immunity. If we let it get out of control again, the future is quite grim, particularly for the >70's, and anyone with asthma, diabetes or on immune suppressant medication.
