EDIT: title should say "his involvement" instead of "hit involvement"
Dr Robert Malone became publicly known after the heightened examination of mRNA vaccines - from Steve Kirsch and others.
Dr Robert Malone appeared on the Bret Weinstein Dark Horse Podcast with Steve Kirsch.
However, Dr Robert Malone's role during covid19 extends beyond just being a pioneer of mRNA.
Dr Robert Malone was one of the group of people who promoted Famotidine use during covid19. Another of his acquaintances had carried the info from China that Famotidine seems to reduce covid19 severe disease.
For background on Famotidine, Dr Malone, Navarro, Michael Callahan and early Chinese findings on Famotidine vs Omeprazole (Risek):

Famotidine (Pepsid) - which is a H2 blocker antihistamine, among other things - and is effectively in reducing symptoms during covid19, and effective for post-vax side-effects (so much so that in my view it should be the standard of care for post-vax - rather than Paracetamol/Tylenol).
Famotidine has been used by long haulers - with a subset seeing reduction in symptoms.
Famotidine action against MCAS (Mast Cell Activation Syndrome) may be the reason for it's effectiveness post-vax.
Dr Robert Malone published a paper on Famotidine:

In addition Dr Robert Malone was the guest editor of the special issue on Repurposed Drugs from Frontiers Open Access.
When the FLCCC MATH+ paper was peer-reviewed/approved, it was then extraordinarily stopped by Frontiers head honcho from being published.
A few weeks later (after it was clear there would be no possibility of being published), the whole staff of that special edition on repurposed drugs resigned (except for 1 member).

Frontiers Pulls Special COVID-19 Issue After Content Dispute
The issue’s guest editors resign after falling out with the publisher over the management of papers, including a rejected manuscript on ivermectin, that were submitted for a special issue on drug repurposing for COVID-19.

This aspect of "MATH+ paper being removed" was not widely reported in the mainstream media - as it would have undermined the negative perception they intended to create around FLCCC and MATH+ protocol.
So Dr Robert Malone has also seen the difficulty papers on generic drugs have had with journal approval.
there doesn't seem to be anything here
