Perhaps this is a good case for a headline that creates a specific thought.
The article states: "Nine of those companies {the ones who are developing/researching a vaccine} on Sept. 8 pledged to put science and ethics first, prioritizing safety over speed in the development of any vaccine they submit for emergency approval. The FDA has since said drugmakers have to meet a higher standard than normal for such authorization."
While Gates may have his reservations about the impartiality of the FDA and CDC he did go onto say in the article: "While acknowledging that side effects are always possible, Gates said he expects a safe vaccine to come out of the development effort {to which I assume he means the efforts the companies are making}."
So I can understand, and actually don't disagree, with having a back of your mind concern about how much political sway is going into the FDA and the CDC I don't quite understand what your "promising" comment means. Sounds like Gates thinks despite issues that he has with the present state of the FDA and the CDC that ultimately a safe vaccine will come out it all somewhere in the world.
