It's like mixing cross ply and radial tyres on the same axle - it's not on, and it's illegal.
True, mixing has not been tested. However it is hardly unknown. It has been a process tested in animal vaccination for more than a decade now (if you use the custom range in Google and exclude 2020 to avoid all the million "Oh My God what are they doing" recent posts).
The point about a vaccine is to produce a response in the human immune system which builds up a defence against a particular pathogen. All articles I have read talk about putting two different live vaccines in the same syringe. Which is pretty stupid as they will do unexpected things.
Giving two different vaccines months apart is highly unlikely to cause a problem in that way. It may not be overly effective, it may promote an unexpectedly strong response to the second vaccine. What else are the doomsayers getting at? Are they saying that stimulating the immune system again, with the signature of the virus, a month or more after the first vaccine, is going to kill/damage people? What happens if they get the actual virus?
The response doesn't add up. It seems that everyone is throwing up their arms and saying "we don't know so you can't do it". Well we do know that thousands of people are dying a week. So what are the answers to that then? Because "we don't know" doesn't cut it.
The more concerning thing here is that the government is discussing doing this without any trials at all. There is time, they could do a phase 1/2 trial in the next 3 months if they wished. Whether this is a result of leaks which precede a measured approach and response I don't know. But at least someone is thinking out of the box, trying to save lives.
