Vaccines can’t make you “shed.”

There’s been lots of misinformation about “shedding” circulating on the internet. So let’s be ✨crystal clear✨.

Vaccines won’t cause your body to shed anything that could be dangerous to anyone.

Vaccines work by teaching your cells to make antibodies for a specific germ (e.g viruses or bacteria). Some COVID vaccines, like the ones made by Pfizer/BioNTech and Moderna, use mRNA wrapped in tiny fat bubbles. Others, like the ones made by Oxford/AstraZeneca or Johnson & Johnson/Janssen, use a harmless virus to get those genetic instructions into our cells. None of them use live (or even deactivated) SaRS-CoV-2 viruses. They all teach our bodies to make only the spike protein, which is not contagious by itself.
