It's amazing how sensitive we are to ACTUAL complications tied to these vaccines. Literally 1 in a million. The AZ vaccine uses the same technology, an adenovirus vector, as does the Sputnik vaccine and a couple others like CanSino. The AZ has the same issue, the Sputnik we will never know. As far as testing, you are NOT going to find a 1 in a million side effect in a trial. Do you stop all adenovirus vectored vaccines over 1 in a million fatality side effect?
Thank you for reminding us that the American public being used as a trial in multiple experimental vaccines where the offending virus has a 99.97% survivability rate.
