https://doctorsandscientistsdeclaration.org/ Dr. Robert Malone, "inventor" of mRNA technology who I referenced in a thread below, is their president.
In addition to the joint declaration (a consensus position linked to above) covering the mRNA "vaccines", natural immunity and "Covid" treatment, Dr. Malone also states, speaking for himself rather than the whole group, (as I recall): mass "vaccination" of the healthy population could turn out to be "one of the world's biggest public health blunders"; that the development (of the mRNA "vaccines") has been rushed and not followed normal procedures; that there are data issues raising concerns about its proper development; that there appear to be notable risks associated with it.
On the current "Covid" variant, he states that because of its mild nature, he may consider changing his advice from giving the "Covid vaccines" only to the vulnerable, to not giving them to anyone, as omicron creates greater imbalance between the risks and benefits. and thus the mRNA "vaccine" may not make sense for anyone. He states categorically that "clearly" more healthy children under 18 would die from having these mRNA "vaccines" than be saved as they are not safe [compared to traditional, fully authorised vaccines, I suppose], hence his current position that they should only be given to those who are vulnerable. He is against any "vaccine" mandate.
