Did you actually listen to what he had to say? He didn't say that nothing will happen before Trump is inaugurated. In fact, he said bad stuff was already happening. He just seemed concerned about what will happen under Trump's (and RFK's) policies if a pandemic or epidemic developed.
I listened to the entire clip multiple times, and Hotez used very poor ways of communicating his point if he was trying to say that he was concerned about what will happen under the new Trump administration. If the current picks for leading the US health establishment are confirmed, I would be way more positive about disease management. Nothing could be worse than the anti-science, ineffective, destructive, politicized COVID debacle run by Hotez, Fauci, Collins, Birx, et al.
The awfulness of the last pandemic panic response has been detailed in testimony from various countries. In Germany, health leaders testified that they were pressured by "outside" political forces to implement the pandemic panic measures, even though those measures were not remotely beneficial or proven.
In the US, Congress has detailed how destructive and politicized the COVID debacle was.
In the UK, health officials admitted to stoking fear, just so people would follow orders.
Knowing all of this, I can't believe how many people still believe the COVID debacle was the most perfect public health response the world has ever seen.
Speaking of the Hotez video, some people forget that Dr. Fauci was saying something similar before the 1st Trump presidency - guaranteeing a surprise pandemic.
Similar to many other fear-mongering pandemic episodes, the same trashy unscientific US media outlets who were wrong about almost everything during the COVID panic, are trying to gin up panic over the bird flu.
