"We should have been primed for the fact that an outbreak of Zika was going to happen."

"That could outstrip capacity that would be likely in the Americas. The warning in the study abstract is right on the mark."

"Despite the industry pointing its finger at the wild birds, [the evidence is] just not there. It was not the source of widespread [avian flu] transmission to many operations throughout the Upper Midwest."

"They [WHO leaders] don't have the authority to do anything. They don't have the resources to do any of it. If we blame WHO for this [response to Zika], shame on us because we're continuing to miss the lessons of these crises. The world's public health governance is a mess."

"If you have an infectious agent that causes Guillain-Barre syndrome, you have to be concerned that the vaccine could cause Guillain-Barre syndrome."

"There are so many holes in this ship. Even if we bail it out as much as we can with all our strength, we might still be sinking."

"What has been unfortunate is this debate for the last month of whether the link [between Zika virus and microcephaly] is proven or unproven. We had clear evidence for public health officials to take action a month ago."

"Why would any private sector company want to invest in these [Zika virus] vaccines? [Companies] are not philanthropic organizations."

"What’s fueled A. aegpyti [the mosquito that transmits Zika virus] is the overabundance of nondegradable biomaterials. Cleaning it up doesn't take research. It takes a will to do it."

"Zika is here to stay in the Western Hemisphere. . . . Even if we make vector control efforts a major initiative, it will only reduce, but not eliminate, the risk of Zika. What we need next, urgently, is a vaccine."

"Some believe we need more scientific data to confirm these more severe manifestations. I don’t agree; I believe the evidence is already compelling."

"Some critics are suggesting that such vaccine research for Zika should have been done years ago, but this isn’t entirely fair. It was only in the past 2 years that there was any indication this virus could cause serious human disease. Now we have to catch up. But it’s going to be complicated."

"We're going to be living for quite a few years in a Zika, vaccine-free world."

"These mosquitoes have adapted very well to our throw-away society. It's not in the swamps where the mosquitoes that spread malaria live. But that discarded fast food wrapper in the ditch could be a very important source of Aedes."

"When you have no other tools to use right now, that’s about the best advice you can give."

"We are in the most tenuous situation with regard to Ebola vaccines that we've seen since we started all of this."

"We're moving mosquitoes around the world at will right now."

"This is why we need game-changing influenza vaccines."

"If we're going to stop the transmission of MERS virus in hospitals, we've got to stop it from getting to humans in the first instance. And the only way we're going to do that is break that interface between the camel and the human."
