CV and mad panic behaviour

According to the scientist I think it was spfs video it showed it actually yields better effects in the UK than it has in Israel.

Yes after the 2nd shot, but a longer interval after only the 1st dose increases the time risk of infection or transmission.

There is not much solid data on the difference between Pfizer and AZ for the Delta variant after only the 1st shot, but both appear to be about 65% effective at that early stage. The people I've heard talking about this suggest cross vaccination is the best strategy to maximise efficacy, but not many regions are doing it. However it's likely they will start to cross vaccinate as Delta grabs hold, so that patients get a strong reaction for both antibodies and T-Cell immunity.
