I've read this before. As far as I know, the data itself is not available, just the news reports. I'm not saying they are wrong, but it's hard to judge without the data.
t does seem to show an increase in antibody response after a single dose and a decrease in a double dose. That is definitely worth pursuing further.
This one is worth looking into further. It would have been nice if they had actually reported what the adverse effects had been.
This one shows greater chance of adverse effects from the viral based vaccines and only minor effects from the mRNA vaccines, similar to normal adverse effects.
