suggest a potential direct association
In other words: WE ARE JUST GUESSING
There is a Prevnar 20 pneumonia vaccine that is being pushed in radio PSAs. The ad has two things that make me wonder ...
One says that an affirmative study may be required for continued manufacturing of the drug. [Huh? So, is it still experimental?]
Another has one of the actors saying something about her needing the injection 'so she can continue with her plan'. [What does her plan have to do with the drug being available?]
I think many of these studies and PSAs are designed to be confusing.
