Our research is out in @bmj_latest today: “Comparative risk of thrombosis with thrombocytopenia syndrome or thromboembolic events associated with different covid-19 vaccines: international network cohort study from 5 Eur countries and the US” bmj.com/content/379/bm…
This is to our knowledge the 1st international study of #covidvaccine compartive safety. We studied the risk of thrombosis and/or thrombocytopenia in the 28d after adenovirus- vs mRNA-based vax in DE, ES, FR, NL, UK, and the US

New paper out today @JTHjournal : "Genetic risk and incident venous thromboembolism in middle-aged and older adults following #COVID19 vaccination" . A short 🧵
1/n) Some #COVIDvaccines have been associated with increased risk of blood clots (VTE). We wanted to understand if genetic predisposition to VTE would predict risk of post-vaccine VTE, and if vaccination interacted with underlying genetics

New paper published in @bmj_latest : “Association between covid-19 vaccination, SARS-CoV-2 infection, and risk of immune mediated neurological events: population based cohort and self-controlled case series analysis”. A 🧵 bmj.com/content/376/bm…1) previous reports and research have suggested an association between some #CovidVaccines and immune neurological conditions including facial paralysis and Guillain-Barré syndrome. We had access to unique data to study this, and to research if #COVID19 itself can cause these

Tres estudios sobre la severidad de #omicron ayer, en un solo dia 🧐. Un resumen despues de leerlos con detalle 🧵TL;DR: es demasiado pronto, necesitamos mas datos con seguimiento mas largo
1/n - 3 estudios con caracteristicas distintas. el de SA tiene mayor N, pero es dificil extrapolar x diferencias socio-demograficas notables y un sistema sanitario muy diferente. Los d Inglaterra y Escocia son mas utiles para ES. Los 3 traen buenas noticias y matices

Oigo aun a mucha gente "minimizando" el impacto de esta quinta ola porque solo afecta a jovenes, y estos no se ponen enfermos. Ojo que hay mucho que perder si no se hacen las cosas bien! 🧵
1.Los datos de Reino Unido dicen que aunque la vacunacion (que por cierto aqui hay mejor cobertura que en Spain) reducira ingresos, no los parara. El numero de ingresos esta semana en UK es >50% superior a la previa, y vamos por >500 ingresos diarios

Una reflexión sobre el concepto de “overshooting”. O por qué se equivoca UK liberando todas las restricciones cuando el país se acerca a la inmunidad de rebaño 🧵
El concepto de inmunidad de rebaño se vende como un umbral mágico en el que la pandemia se desvanecerá. Pero esto, por supuesto no es así. Lo que ocurrirá es que la R bajará (y se mantendrá) <1, y la pandemia remitirá progresivamente
