Professor Bret Weinstein, once a strong supporter of vaccines as a modern medical triumph, has publicly reversed his stance, calling the mRNA vaccine platform “fatally flawed” and raising doubts about the safety of the current childhood vaccine schedule.
Weinstein was previously a professor of evolutionary biology.
In a candid interview with Piers Morgan, Weinstein claimed the mRNA platform contains inherent hazards that cannot be fixed, pointing specifically to risks of myocarditis and pericarditis. He argued these heart conditions result from the immune system attacking cells in the heart that produce a foreign protein following vaccination.
Weinstein also challenged the idea that mRNA vaccines offer a rapid solution in a pandemic, warning that their narrow antigenic target allows viruses to adapt quickly, potentially prolonging outbreaks. He further asserted that certain vaccine platforms are unsafe and that the cost-benefit analysis does not justify the use of some childhood vaccines. Instead, he advocated improving population health to control diseases like measles by non-vaccine means.
The discussion grew heated when Weinstein criticised adjuvants — compounds added to vaccines to boost immune response — claiming they could trigger allergies and other long-term health issues. He argued that the scientific literature lacks properly controlled studies comparing deaths caused by vaccines to those caused by the diseases they aim to prevent.
Weinstein, who last year spoke with vaccine critic Del Bigtree, said he was shocked to learn that some childhood vaccines use non-specific aluminium adjuvants, which he believes may cause lifelong allergic reactions to foods or environmental triggers.
In a stunning admission Weinstein explained why he no longer viewed vaccines as a medical triumph.
A number of vaccine platforms are not safe.
The cost/benefit analysis of using certain childhood vaccines is not there.

Wait what? Is everything that has been said about vaccines or gene therapy masquerading as a vaccine all a lie?
Though I am not a fan of jews and fact-check every word that comes of of any of their deceitful mouths and have great reservations of anything they say even if I cant initially find the hook in the bait I do remember Mr B Weinstein expressing deep reservations about the mRNA vax for several years, even though he initially to the shot, he had near instant regrets and has been talking about if for several years.
At least it’s not his brother Eric who’s got an ego rivaling a Black Hole.
Michal Laws has something to say about the enquiry that those responsible didn’t show.

This isn’t news. Brett Weinstein has been a covid dissident from the start. He has been against the mRNA/covid vaccine since it came out (and very publicly didn’t take it). He very publicly had another look at vaccine safety shortly after this (ie almost 5 years ago now), admitted that he and his wife had gotten it wrong and came out against all vaccines at this time.
