> it was they that were raising doubts about the vaccines when Trump was president From the article and the video of the interview which the article describes: Harris is discussing the fact that she doesn’t trust Trump, and that this mistrust extends to his claims towards the efficacy of the vaccine. This does not imply that she (or democrats) were raising doubts about the vaccine in general, in fact she follows her statement that she would trust a credible source on the matter.
