There had been these cases of contaminated vaccines (with an Avian strain) in the Czech Republic, Austria, and possibly other European countries. That actually happened.
It just stretches credibility that they had a vaccine ready for a mutated hybrid swine-human-avian never seen before. How was there time to test that? Who was tested, when and where?
I thought I remembered some high-blown pandemic talk about SARS- but this seems a little different.
As to vaccines being ready so early- I’m thinking perhaps he meant something like tamiflu. A vaccine couldn’t be developed for this specific flu yet.
