It seems like it's more likely existing drugs are grandfathered in, but approvals might be more difficult.
Novavax, a vaccine for Covid that has low reactogenicity and confers better cross-variant immunity and longer efficacy than its competitors, just had its BLA punted on by the FDA. RFK was asked about the deferral, and he said "It is a single antigen vaccine. And, for respiratory illnesses, the single antigen vaccines have never worked." Source:
Key takeaways from RFK Jr.'s interview on measles vaccine, food dyes, weight loss drugs and more
This is despite the fact that Novavax tested a bivalent vaccine and found it had worse protection than one producing immunity to a single antigen. And this is a non-mRNA vaccine, which should appeal to people skeptical of mRNA vaccines.
And it's also despite the fact that RFK recently conceded that measles vaccination is the best way to prevent measles. I guess he could claim that the MMR vaccine is not single-antigen, but it was available as a single-antigen shot I believe for a couple of decades prior to the MMR shot.
Anyhow, Novavax continues to be available under its EUA, as are the mRNA vaccines that do have BLA but also produce immunity to a single antigen, which is apparently supposed be a non-starter.
That's why I surmise the MO will be to deny approvals rather than pull existing pharmaceuticals. There was no reason to deny the Novavax BLA except for some form of neuroses combined with unwarranted confidence.
The FDA also canceled the meeting that was to select flu strains to target for fall.
So I think change is in the pipeline but it's about ending the pipeline, so to speak.
I'm usually fairly non-reactive and equanimous, but it's difficult to watch a former heroin addict be so wrong and haughty at the same time in a way that limits people's choices because it mirrors family dynamics I've experienced.
If society let you try heroin and didn't imprison you (as is afforded any Kennedy for any crime), let someone else try a vaccine. These people who get religion and then want to police everyone else—and not even beneficially—have a special breed of ego.
