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.
