Today I thought it would be useful to discuss phases of managing pandemics, as this is something that doesn’t get discussed often enough. When I spoke earlier in the week about contact tracing etc. I forgot my own professional understanding and this thread might help. Management of pandemics tend to fall into phases which overlap and tend to fall along a continuum. Public health actions changes and modify throughout, this is how we have managed previous pandemics.

I'm going to do a thread on sums in a pandemic and vaccine uptake and infections.
It's hot so forgive any typos in advance.

A fictional population of 1000 people. Vaccine uptake of 80%, so 800 vaccinated and 200 not. Vaccine is 80% effective in preventing infection.
Transmission increases and all those unprotected get infected.

That's the 200 unvaccinated and 20% of the vaccinated, that's 160.

So looking at the infections it would look like 55% are unvaccinated and 45% are vaccinated.

I think it's really important to look at our daily numbers and realise

1. Diagnosed infection is always the tip of the infection iceberg, our true daily rate is a multiple of that.

2. Younger people are the unvaccinated ones and are also likely to have fewer/no symptoms. What critical is how the case numbers relate to hospitalisations/mortality. We will know more in the coming weeks and be able to learn from our neighbours.

I'd also like to talk about some good examples I've heard from businesses in relation to the Covid vaccination programme. An employer asking their admin staff to help register their staff for immunisation if they wanted help. Actually including this in their work day.

Let's talk about employees being allowed to leave during working hours to attend their Covid vaccination appointment.

I think this is utterly critical that this is facilitated.

Every cancellation/rescheduling slows the vaccination programme or risks vaccine waste. It is hugely beneficial to a company to do this, shows a duty of care to their employee and protects their busines from outbreaks. It is a no brainer.
