Do COVID vaccines cause cancer 17 different ways?

Peter McCullough’s group is pointing to several studies that they say show 17 different ways COVID vaccines could cause cancer.

The study mentioned in the video says there may be a link between cancer and the COVID vaccine. It was a study from South Korea that looked back at health records. The study seemed to suggest that people who did not get a COVID vaccine had a lower cancer risk than people who did get vaccinated.

But there are some big problems with that idea.

One problem is that the study looked back at records instead of carefully following people from the start. This kind of study can miss important differences between groups. For example, people who get vaccinated may be more likely to trust doctors and go to medical checkups. That means they may be more likely to find cancer earlier than people who do not go to the doctor as often.

The graphs in the study also raise questions. In one graph, cancer diagnoses start at zero on the first day of the study. Then the lines for vaccinated and unvaccinated people begin to separate almost right away. If the vaccine were causing cancer, that would suggest the vaccine could cause cancer almost immediately. That does not make sense. A more likely explanation is that vaccinated people were seeing doctors more often, so more cancers were being found.

Peter McCullough’s group also suggests several ways they think COVID vaccines could cause cancer. We have already explained why many of these claims are not supported by good evidence.

One example is the claim about “SV40 DNA sequences.” Many years ago, some early polio vaccines were accidentally contaminated with SV40, a virus found in monkeys. This happened because the process used to kill the polio virus did not fully kill SV40. But large studies later followed people who got those vaccines. Those studies did not find higher cancer rates in those people.

Today, scientists sometimes use a tiny piece of SV40 DNA in labs. This piece is called a promoter. A promoter is like an “on switch” that helps cells make proteins. It is not the part of SV40 linked to tumors.

In making some mRNA vaccines, this tiny “on switch” may be used during manufacturing. But almost all of it is removed before the vaccine is finished. It is not considered an ingredient in the final shot.

The evidence does not show that COVID vaccines cause cancer. In fact, some studies suggest that mRNA technology may help the immune system find and fight cancer cells. Scientists are also studying whether mRNA technology could help treat cancer in the future.
