UPDATE: Risk Serious Blood Clots following Astra Zeneca/COVISHIELD vaccine. #VITT
~1 in 55,000 with 1st dose.
This is higher than we thought initially.
Risk with 2nd dose is 10 times lower.
I'd favor mRNA vaccines, if possible, for age <30 years. covid19-sciencetable.ca/sciencebrief/r…

As the report indicates, the risk from countries with moderate to high data data quality range from 1 in 26,500 to 1 in 127,300 of first doses.
My previous estimates are in this thread from April. There are relatively smaller number of J&J doses. So erring on side of caution for now I would consider risks to be similar.

The risk of dying from these clots is 20-30%.
More on how these clots are different from regular blood clots and the mechanisms involved see below.

People are asking about symptoms. It is severe persistent headache or abdominal pain, dizziness, not feeling well.
The key is to recognize the symptoms based on recent history adenovirus vector vaccine and initiate the right diagnostic work up on time.

IMPORTANT: In countries like India, with high rates of COVID, no mRNA vaccines, and limited vaccine supply, the risk of COVID far outweighs the risk of adenovirus vector vaccine like COVISHIELD.
So even for my family <30, I have recommended getting the first vaccine offered.
