Can spike proteins attack your unborn baby?

The Claim:

In an interview on Alex Jones’ Info War, former vice presidential candidate Nicole Shanahan argues that mRNA vaccines are unsafe and unpredictable, causing health problems like blood clots and irregular menstrual cycles, and believes they need more testing before use because they treat the body like a machine, which could lead to harmful, long-term effects.

The Facts:

Our mRNA vaccines have been well-tested. Serious side effects are extremely rare, and most reactions, like sore arms or mild fever, only last a short while. Scientists have been studying mRNA for decades, and due to prior research, its use in vaccines was accelerated during the pandemic. Clinical trials involved tens of thousands of participants, and millions of people have safely received these vaccines since then.

The idea that COVID vaccines cause “turbo cancer” has no scientific backing. Even the most potent carcinogens take years to cause cancer. It would be some time before we saw spikes in cancer. Epidemiological data show no increase in cancer linked to the vaccines. Reports of rising early-onset cancers started in the 1990s, long before the COVID vaccines existed.

The idea that mRNA vaccines cause “shedding,” where vaccinated people somehow affect unvaccinated individuals, is a misunderstanding of the science. Shedding refers to live viruses used in some vaccines, but mRNA vaccines do not contain live viruses, so shedding is not possible. For example, the Pfizer and Moderna vaccines use a small piece of mRNA that teaches cells to make a harmless protein to trigger immunity. This technology cannot spread or alter someone else’s body.

Comparing mRNA vaccines to genetic modifications in plants or animals shows a misunderstanding of how these technologies work. mRNA vaccines do not alter DNA or cause mutations. Instead, they give temporary instructions to cells to produce a protein that trains the immune system to fight a virus. These instructions break down quickly and leave the body after doing their job.

Finally, claims about mRNA vaccines being part of a harmful agenda are unfounded conspiracy theories. Scientists worldwide have worked transparently to develop these vaccines to save lives during a global crisis. Dismissing them ignores the evidence of their role in reducing severe illness, hospitalizations, and deaths from COVID-19. Misinformation about vaccines can create fear, but credible scientific sources provide clear information to help people make informed decisions.
