In an interview with Joe Rogan, actor Woody Harrelson claims that RFK Jr.’s spasmodic dysphonia, which makes speaking difficult, was caused by the flu vaccine.

Spasmodic dysphonia is a rare disorder that makes it hard for a person to control their voice because the muscles in their throat move in an unusual way. Scientists don’t fully understand what causes it, but doctors believe it happens because of a mix of genetic factors and environmental influences. There is no scientific evidence that flu vaccines cause this condition.

Robert F. Kennedy Jr. developed spasmodic dystonia in 1996, but in 2021 or even in 2023, he wasn’t making mention of it being flu vaccine-related.

Flu vaccines have been studied for many years, and millions of people get them safely each year. They help prevent serious flu infections, which can lead to hospitalization or even death, especially for young children, elderly people, and those with weaker immune systems. The flu vaccine is an important tool to keep people healthy and reduce the spread of influenza in communities.

In a Politico interview, Del Bigtree claims that vaccine studies are biased, don’t compare fully vaccinated and unvaccinated people, and ignore rising health problems like autism and cancer. He also argues that pharmaceutical companies control the research to hide possible risks.

Bigtree has a long history of spreading false information about vaccines, and he has worked closely with Andrew Wakefield, the discredited former doctor who started the false claim that vaccines cause autism. He played a key role in producing the film Vaxxed with Wakefield, which pushed his false claims that vaccines cause autism.

Many studies have compared vaccinated and unvaccinated people and found no link between vaccines and autism. A large 2019 Danish study followed over 650,000 children and found no connection between the MMR vaccine and autism, even in kids with a family history of autism. It used nationwide health records to track children for years and compared vaccinated and unvaccinated groups while controlling for other factors like genetics and birth complications.

The study also checked if autism cases spiked right after vaccination or if MMR triggered autism in certain children but found no evidence of either. Unlike what anti-vaxxers claim, this research was independent, not funded by drug companies, and used strong scientific methods to ensure accurate results.

The findings confirm that MMR does not cause autism, does not increase autism risk in any group, and does not lead to autism clusters after vaccination, making it one of the strongest studies proving that vaccines are safe.

Another meta-analysis came to the same conclusion. This study analyzed data from over 1.2 million children in five large studies and more than 9,000 children in smaller case-control studies, making it one of the most powerful investigations on the topic.

The results clearly show that vaccines, including the MMR vaccine and ingredients like thimerosal, do not cause autism or increase the risk of autism spectrum disorder. This research includes data from multiple independent studies conducted in different places with large, diverse groups of children. Since this study reviews multiple high-quality studies instead of relying on isolated or flawed research, it provides strong evidence that the claim that vaccines cause autism is false.

Autism is linked to genetics and prenatal development, not vaccines. Studies show that if one identical twin has autism, there is a high chance the other twin will, too, even if they were never vaccinated. Research also shows that brain differences in autistic children start developing before birth, long before any vaccines are given. Scientists have studied many possible causes, and vaccines are not a possible cause.

A large outbreak of measles in Texas and now New Mexico has anti-vaxxers claiming  that the measles vaccine can spread the virus to others, causing the recent outbreak.

The MMR vaccine, which contains a weakened form of the virus. While this weakened virus can be detected in the body after vaccination, it is highly unlikely that is will cause disease in other people. In fact, there has never been a confirmed case of the measles vaccine causing someone else to contract the disease.

The recent measles outbreaks in Texas and New Mexico has spread mostly among unvaccinated people. In Texas, out of 124 reported cases, the vast majority were in unvaccinated, with only five cases in vaccinated people.

We can conclude that the vaccine people are getting does not cause measles in them. If the measles vaccine were spreading the disease, we would expect to see higher rates in vaccinated people, but the opposite is true. We also know that all samples tested in the outbreak have come back as genotype D8, a known strain of the wild measles viruses. The genotype for the vaccine virus is Type A. So it really isn’t the vaccine. It’s the unvaccinated.
