The alternative I was referring to is wherever Enrico Weigelt got his information, which certainly was not a vaccinologist.

Of course, if you have access to a vaccinologist (is this a recognized profession? I checked two dictionaries and neither contain the word), you should ask them. Or you can look up their opinion online [1]. Most will agree what the doctors and nurse said.

I have some more questions (serious), can I have the number of one of these people?

Point being, it's not that straightforward unless there's someone you already know that is willing to share their contact information and they actually have the time to talk to you.

I totally see the point about going for second-best first until you know you have a question worth their time and not something that's obvious. (Although the answer in this case did seem obvious to me as a software person, or at least I'd have guessed they can see the amount of anti-covid-stuff dropping at different rates.)

Contact the department of health education of the ministry of health. You already paid for it with your taxes, might as well make use of it.

Yeah I've done that two or three times about different things. One time I got an answer, the other (reporting an outdated page) an automated reply five days later that they're too busy. I don't expect they have time for in-depth questions about research that's not even a month old. Thanks for the tip though!

Sorry, I didn’t read all of of the original comment earlier.

Now I see where you’re coming from with the suggestion to go straight to a qualified source instead of asking a bunch of random people.
