Uh, no. Every scientist you are allowed to hear on TV agrees, otherwise they wouldn't be interviewed ON TV. So when you do a little digging on what happens to scientists who do speak out against vaccines, this is what you find. This poor guy, who just wanted to do his study and probably continue with his successful career, ended up bumping into information that nobody wants to hear, i.e. that the aluminium injected into a body creates havoc (don't say! I'm so shocked). What happens to him? He lost his research funds. Because that's how "real science" is carried out... Wipe out anything uncomfortable.
(This interview is in French with English subtitles)
Luckily for us, there are still people with integrity in the scientific community, and he must be one of them, because he doubled down by sending this letter to the US Department of Health and Human Services, where he dares to mention the "A" word.

The following day, another researcher follows suit.

And then what happens? A third scientist comes forward with this

"They're all quacks!" I hear the screams from pro vaccine advocates. Of course. Exley being one of the leading experts in the world on aluminium would make him an instant quack, right? >>> vaccine logic<<<
If you're a vaccine apologist, please refrain from commenting with the usual pointless accusations or by posting pictures of how bad the measles can be (in undernourished or immunocompromised children). Unless you're willing to have an honest conversation about vaccine injury, you're wasting your breath here.
They are not quacks, they are scientists. Using the scientific method they have taken a theory and tested it. The results have been forwarded for peer review. They have all failed peer review. It is called "The Scientific Method".
It can be quite funny, and scientists find themselves testing very strange theories or ideas. The more bizarre ones are awarded here https://www.improbable.com/ig/winners/
This is good stuff and on occasion something good comes from it - like the guy that looked at the properties of tangled string then came up with a solution to headphone cables. Something we all are grateful for.
So the guys you cited above are not necessarily quacks, they are scientists and they believe that they have discovered something. As yet nobody has been able to recreate the science nor validate the theory. If they do, something will happen, if they don't there is no need.
None of the scientists cited above question the effectiveness of the vaccines themselves by the way, so they are not speaking out against vaccines.
The vaccines work, the three scientists cited above agree.
