Next-up - Karina-Doris on Iterative sequential regression for real time surveillance of infectious diseases
A taster from the 2nd of the 8 lecture 'Introduction to University Mathematics' course that our students take at the outset of their @OxUniMaths life, as we prepare them for the step up from high school. You can watch lecture 2 here. We are showing all 8. youtube.com/watch?v=UCev1n…

I know currently, and rightly so everything is focused on Coronavirus, but am glad this paper finally made it out (albeit through a rocky course) TY @stat_sarah @NicStoesser and all my colleagues who helped with this, and keep safe! aac.asm.org/content/early/…
Our work on the effectiveness of COVID-19 vaccines against infections with the Delta and Alpha variant is now published nature.com/articles/s4159…. Protection by two doses of Pfizer (BNT162b2) or AstraZeneca (ChAdOx1) better or similar to previous infection, respectively. However,
Pleased to see our study estimating the effectiveness of Pfizer and AstraZenaca vaccines against infections overall, (a) symptomatic infection, and viral burden. Great work from @emmapritchy using ~2 million swabs taken independent of vaccination/symptom status.

2 major studies from @ONS Covid Infection Survey (370k people) - 72% reduction in symptomatic infection after 1 dose of either Pfizer or AZ vaccine, 90% after 2 doses of Pfizer. Strong rises in antibodies after 1 dose of either medrxiv.org/cgi/content/sh… and medrxiv.org/cgi/content/sh…
Fantastic data showing 65% reduced chance of catching Covid from 1 dose of both Oxford and Pfizer vaccines. Vaccines are our way out. bbc.co.uk/news/health-56…
