The official story right now is that it has been superseded by "updated" vaccines.
In its statement, AZ said:
"As multiple, variant Covid-19 vaccines have since been developed there is a surplus of available updated vaccines [...] According to independent estimates, over 6.5 million lives were saved in the first year of use alone and over 3bn doses were supplied globally."The "lives saved" estimate is an interesting one, repeated all over the place despite making almost no sense (but that's a fact-check for another time).
More interesting is that neither AZ's official statement nor the write up in the Guardian mentions the ongoing civil action seeking damages in excess of ยฃ100 million for those who suffered the "rare side effects" of the vaccine.
In fact, just last week the Telegraph reported that, in court documents, AstraZeneca admitted their vaccine caused thrombotic thrombocytopenia in some people (allegedly 2-3 out of 100,000).
