My Coronavirus model post-Pirola

I have updated my Coronavirus model to include an assessment of the potential impact of the new BA.2.86 Pirola variant. The model factors in age-group structures, transmission rates, vaccination phases, and non-pharmaceutical interventions. The model finds that despite reported decreases in Covid-19 cases in the UK, case recording has been high with recent data seeming erratic, with some inadequacy in the data reported by the Office for National Statistics (ONS) after it ceased its regular reporting. I source data from Worldometers, providing reliable Covid-19 figures. The accuracy of the model may be compromised by lower reliability of active case data.

Declining Omicron cases but increasing deaths – Coronavirus

Something odd seems to be happening with the relationship between reported UK Covid-19 cases and deaths in the last few weeks, when deaths have been increasing somewhat more quickly than recently, but cases have declined steeply. My model charts seem to expose this oddity.

Modelling of Coronavirus vaccine strategies

In my most recent post on November 18th, about updating my Coronavirus model to handle the impact of vaccines, I gave some examples of how case numbers, and more specifically death rates might be improved for the UK through a vaccination programme. Now that there seem to be several vaccines imminent, with efficacies ranging from 70% (Astra-Zeneca/Oxford) through 90% (A-Z/O via a different inoculation regime, and Pfizer), to 95% (Moderna) and several others in the mix, I explore some sensitivities in more detail, and also apply the model to the USA.
