"“Our scientific position is that this vaccine is a safe and effective option to protect citizens against COVID-19,” said the head of the EMA, Emer Cooke.
She added: “If it were me, I would be vaccinated tomorrow.”"
2) However, the EMA “cannot rule out definitively a link” between the rare types of blood clots and the vaccine.
They are therefore recommending to add a description that such cases have been reported, to the vaccine leaflets, to make health workers and patients aware of this.
3) Note however that this would be a very rare event, 37 or slightly more out of 17 M recipients, bringing the reported ratio to ~ the reported rate of anaphylaxis for Pfizer & Moderna (2.5-4.7 per 1 million doses) - just from a numbers comparison. jamanetwork.com/journals/jama/…
"considers that the benefit-risk balance of the medicine remains positive, & there is no association with thromboembolic disorders overall. However, steps will be taken to update the SmPC & package leaflet with information on cases of DIC & CVST that have occurred"
5) The EMA acknowledges that there have been very rare (n=5 out of ~20 M) cases of an unusual type of disrupted coagulation (DIC) after vaccination. These cases were mostly seen in women under the age of 55, but casuality cannot be confirmed or excluded. ema.europa.eu/en/news/covid-…

German researchers seem to claim that in some individuals - that is, in very few as reported elsewhere - the Astrazeneca vaccine may activate platelets (which regulate clotting) ndr.de/nachrichten/me…
The upside is that they seem to think they know how to treat these rare complications:
"The discovery means that targeted treatment can be offered to those who suffer similar clotting, using a very common medication."
3) Some more details regarding the possibility of the rare clotting/bleeding complications following the Astrazeneca vaccine, and how to possibly treat the more serious type of them:
2) The @TheLancet article describes how Denmark during tested ~0.5 M people for #SARSCoV2 during wave 1.
At the end of 2020, ~10% of the population tested every week.
In all of 2020, Denmark tested ~4 million people (68% of their pop.) and 64% of those had been tested >1 time.
3) In their analysis, they also included an alternative cohort, that looked at individuals throughout the pandemic (& not only those testing positive in the 1st & 2nd wave), thus examining reinfection risk in a group of 2.4 M people, of which 28 875 had been previously infected.
2) An array of papers that attempt producing human blastocysts from pluripotent cells, including from fibroblasts (the type of cell often used to make induced pluripotent stem cells).
3) Tear gland organoids that could produce tear fluid ("cry"), engineered in a dish. This could potentially in the future be useful for treating conditions such as Sjögren's syndrome, where tear production is severely lacking.
Lovande: En ny analys av vaccindata från #Moderna (#mRNA1273) i @NEJM finner att nivåerna av #antikroppar hos de vaccinerade deltagarna ligger kvar på höga nivåer hos samtliga deltagare ~3 månader efter att bägge vaccindoser har givits.
De fann neutraliserande antikroppar hos samtliga deltagare dag 119 (dvs. ~3 månader efter andra dosen; doserna ges med 28 dagars mellanrum).
Analyserna tyder på något lägre nivåer av neutraliserande antikroppar hos de äldre (56-70 & ≥71 år) jämfört med yngre (18-55)

Vid denna tidpunkt var också antikroppssvaret bättre än de som sågs hos individer som återhämtat sig efter en naturlig COVID-19-infektion (konvalescenssera), och som undersökts betydligt tidigare (~34 dagar) efter sin motsvarande exponering (dvs. efter en COVID-19-diagnos)

De beräknar även infektionsmönstret i de analyserade länderna. Studien finner att IFR är lägst i åldern 5-9 (0.001%), för att gå upp till 8.29% hos de som är ≥80 år (se Fig. 1A, kom ihåg det är en log-linjär skala).
Notera att studien är accepterad men ej editerad ännu.
2/n
Många västländer hamnar på IFR 0.6-0.8%. I snitt hade 5% av invånarna i de undersökta länderna smittats fram till 1:a september i år (med en högre siffra för Latinamerikanska länder; utifrån seroprevalensdata).
