Anything is better than nothing and the A-Z vaccine can be produced quicker and cheaper.
That said, they are actually looking to delay the second doses of the Vaccines. They "THINK" it will be better to get as many people as possible an initial dose. Once they have most people with an initial dose, they will then start to administer the second dose.
They do not know how effective this will be, as they did not run the trials this way!
I think most of the people who contracted COVID-19 who had the Pfizer or Moderna vaccines probably we between the first and second dose and probably in the first week or so.
