What’s in the Vaccines and Boosters?
Quick Summary: The COVID-19 vaccines don’t have anything harmful in them and do not contain any metal, magnets, mercury, microchips, stem cells, or egg products.
During the pandemic there has been an issue with the spread of misinformation regarding the COVID-19 vaccine. Vaccines, including mRNA vaccines, do not rewrite our DNA. They do not have the components needed to do that, and there is never any contact between the contents of the vaccine and our own DNA. There are also no metals, magnets, microchips, mercury, stem cells, or egg products in the vaccine. Really, what’s in them is standard for any vaccine:
The Pfizer and Moderna vaccines are made of mostly the same things:
mRNA, which is the part that your body will learn from to fight off COVID-19; it cannot infect you in any way.
Special fats (also called lipids) to help your body interact with the mRNA.
Both vaccines also contain salts and sugar, and the Moderna contains additional acids to keep the other parts of the vaccine fresh while it’s being shipped to you (so that it still works when you get it!).
Think of the vaccine ingredients like shipping a crystal vase: The mRNA is the fragile contents, the lipids are the bubble wrap, and the salts/sugars are the packing tape. Basically, everything is designed to help the vase get delivered without breaking!
The Johnson & Johnson vaccine is made of two parts:
Harmless bits of a virus, which is not COVID-19 but is made to look like it to your immune system; your body will learn from this virus to fight off COVID-19, but it cannot infect you in any way.
Salts, sugars, and acids to keep the other parts of the vaccine fresh while it is being shipped to you (so that it still works when you get it!).
When it comes to boosters, the overall ingredients are the same, just different amounts.
