First analysis in stroke patients was a #dose-scalation safety study
There was no #symptomatic ICHs in dosis of 0.1-0.2-0.4mg/kg, and 15% (2 of 13) in 0.5mg/kg
No differences in clinical outcomes

How well are the current #Covid vaccines performing?
In all fairness, we can say they are offering high protection against severe disease & deaths; considerable protection against the symptomatic disease; but only modest protection ag. infections/transmission of the disease 1/

To put it another way, the vaccines are contributing little to our fight against the frequent surges of the #SARSCoV2 virus.
This leads to one pertinent question:
What ought to be the prime objective of the vaccination particularly amid an intense pandemic? 2/

A four-fold reduction in the hospitalisation & death rates is not much use if we just allow infections to reach four-fold the previous peak. 3/
