So our dearly unbeloved Boris thinks he’s going to end all lockdown restrictions on 21 June. All I can say is that like everything which emanates from BJ’s mouth this is either madness or fiction – and quite possibly both. Let’s take a look.
[Links to some relevant BBC News reports at the end.]

1. Lockdown ends on 21 June. But all UK adults aren’t going to be offered their first vaccination until 31 July. When do they get their second jab? Well at least 3-4 weeks later, which takes us effectively until the end of August, or 8+ weeks after 21 June. So we have a minimum period of 8 weeks with no lockdown and with the UK not as fully vaccinated as it can be. Does not compute.
    
2. Can we hit the 31 July target? Given that the rate of vaccination is reported to have fallen in recent days, partly due to a lack of vaccine supply, this seems unlikely. Moreover the priority sequence for those under 50 has not yet been decided. Yes, it might be possible if we get the volume of vaccine we need. But there’s many a slip ‘twixt cup and lip.
    
3. That is ignoring that we don’t yet have very much data on the effectiveness of the current vaccines against the new variants of the virus. Nor are there updated vaccines available (or even nearly so).
    
4. So lockdown is eased in five steps on 8 March, 29 March, 12 April, 17 May and 21 June. (The media are reporting this as four stages by lumping together the two March dates.) These appear to be the earliest dates for each round of eased restrictions. They will only happen if four conditions are met:
   • The coronavirus vaccine programme continues to go to plan
   • Vaccines are sufficiently reducing the number of people dying with the virus or needing hospital treatment
   • Infection rates do not risk a surge in hospital admissions
   • New coronavirus variants do not fundamentally change the risk of lifting restrictions

   WTF do these conditions mean? They are flabby and woolly at best. Without specific numbers against them, published up-front, they’re worthless as the government can flex them any-which-way it likes. They’re about as ethereal as mist.

5. When they return to school, secondary school children will be required to have two Covid (lateral flow) tests a week. It seems the first three will be conducted in school but thereafter parents will be expected to administer the tests at home and report the results to the school. How many parents will (a) bother administering the tests, (b) do the tests properly, and (c) report the results accurately? This is going to end well, isn’t it!?

I’m not even going to talk about the rest of contents of each round of restriction easing. As you’ll realise from the above it is all rather academic when we don’t know the detailed baselines and criteria being used.

But what I will say is that if this timeline is adhered to, we’ll most likely have an up-tick in cases in May (as a result of schools going back) and another one in August (due to incomplete vaccine coverage).

Now don’t get me wrong. I want to see lockdown removed just as much as anyone else. But I want to see it done safely. For everyone’s sake.
