I dislike anthropomorphizing the virus. The virus just goes into lungs. Replicates. Gets expelled into air and re-infects as long as the rebreathed air containing the virus can find another

Great summary and we really need to take the toxicity out of this. Agree with >95% of what is here. Thx for taking time to do this. The big challenge

As overall infection was reduced, this would suggest that the AZ vaccine does reduce infectiousness so some degree. But even if all adults were vaccinated, it probably wouldn't achieve herd
