I like how you completely ignored the part where I said "that doesn't matter" and argued the wrong point anyway.
Whether you consider them reputable or not doesn't matter. Those are THE organizations (some of them, anyway) that decide these things. They are THE experts in the field. If a person were to say "a lot of people/organizations say , so it must be true", that would be argumentum ad populum. But since they are saying "a lot of <authorities/experts in the field x> claim , so it must be true", that's not a fallacy, that's a valid appeal to authority.
CDC, WHO, NIH, etc. could all be wrong, they could've interpreted the "scientific evidence" incorrectly and come to the wrong conclusions. But we know that this is an unlikely scenario for so many independent experts in the field to reach a consensus on something that is wrong. Therefore, our best bet is to trust their conclusions.
To reiterate, whether those organizations are right or wrong doesn't matter, because they are not a random majority—they are the organizations you're supposed to rely on in this situation; it's a valid appeal to authority. Hence, it's not a fallacy, let alone argumentum ad populum.
And the organizations from the post must have their evidence for making their claims. Otherwise they wouldn't be considered reputable.
But that doesn't matter, because you still misused the fallacy.
But you did.
This isn’t an argumentum ad populum fallacy because the argument isn’t based solely on the number of people or organizations making the claim; it's based on the authority and credibility of these entities.
Whether you agree or disagree with those entities and question their credibility is a separate matter, but it's not argumentum ad populum. For the same reason the following isn't:
The Centers for Disease Control and Prevention, the World Health Organization, the American Cancer Society, the American Heart Association, and the National Institutes of Health all claim that smoking causes lung cancer and heart disease, so it must be true.

It's sort of how if you hold a slinky on one end hanging down, then drop the slinky, bottom will not start falling until the top reaches it. In a sense, bottom will be hanging onto nothing. But of course that nothing is tension from the top of the slinky.
It's weird to say that light travels faster than information, because light is information. In other words, top speed for information IS speed of light.
