  2. The following is a list of ingredients for the Pfizer-BioNTech and Moderna COVID-19 vaccines, as reported in the prescribing information for each vaccine. Note: Both the Pfizer-BioNTech and Moderna COVID-19 vaccines contain polyethylene glycol (PEG). PEG is a primary ingredient in osmotic laxatives and oral bowel preparations for colonoscopy ...

    Messenger ribonucleic acid, or mRNA, is the active ingredients in the vaccines — it’s what helps your body develop immunity. mRNA is genetic material that contains the instructions for how our body makes the viral protein that triggers an immune system response to help fight or protect our body from infection in the future. The instructions in this...

    The Johnson & Johnson vaccine does not use mRNA, described above, to build an immune response against COVID-19. Instead, it uses a different virus, an adenovirus (the common cold), to show the body what COVID-19 looks like. The adenovirus is modified so that it is not able to cause illness or create more viruses in the body. It is designed to deliv...

    If you remember back to biology class, you might remember that lipids are the scientific term for fatty substances. Simply put, lipids are fats and oils. That avocado toast you had at brunch? It had lipids in it. The olive oil in your pasta? Lipids. Most food contains lipids that the body then stores for energy. The membranes of the cells in our bo...

    Acids are everywhere. Like lipid, acid is a molecule that is found in many of the substances we eat and drink. In foods, we associate acids with anything that tastes sour, such as lemons and limes. You might associate acids with the pH scale — any substance that measures less than 7 on the pH scale is acidic. Acids are also found naturally in the h...

    We all know what salt is. But did you know salt comes in many forms? What we call table salt (sodium chloride) is a mineral that is actually part of a larger class of salts (a type of chemical compound). For the human body, salt is a vital electrolyte that helps transmit nerve impulses and fuels our muscles. Our health depends on the right balance ...

    Sucrose, or sugar, is a carbohydrate that is found in fruits and vegetables. It’s produced by plants through photosynthesis, the process of converting sunlight to energy. Our bodies convert sugar in our food and drink into energy. Sucrose helps maintain the stability of the vaccine, like other ingredients. It also helps the molecule keep its shape ...

    There are a few other ingredients, which all appear in the Johnson & Johnson vaccine, that don’t fall under the chemical compounds listed above, like lipids and salts.

    Those who have had an allergic reaction to any ingredient in the COVID-19 vaccines should consult their doctor to determine which one is safe for them. Read more on the CDC’s website.

  3. This Vaccine Information Fact Sheet contains information to help you understand the risks and benefits of COMIRNATY (COVID-19 Vaccine, mRNA), the Pfizer-BioNTech COVID-19 Vaccine, and the Pfizer-BioNTech COVID-19 Vaccine, Bivalent, which you may receive because there is currently a pandemic of COVID-19.

  4. Dec 9, 2020 · The new vaccine, delivered as a shot in the arm muscle, contains an RNA sequence taken from the virus itself; it causes cells to manufacture the big “spike” protein of the coronavirus, which the...

  5. Mar 23, 2023 · Sugar and acid stabilizers. All versions of the Pfizer COVID vaccine contain sugar (sucrose). This ingredient helps keep the molecules in the vaccine stable, especially at different temperatures. When the Pfizer vaccine was first authorized, it also contained salts to help maintain the vaccine’s acidity and stability.

  6. Feb 10, 2021 · The Moderna vaccine contains similar ingredients such as: Messenger ribonucleic acid (mRNA) encoding the spike glycoprotein of SARS-CoV-2. Lipids, or fatty substances, including: SM (sphyngomyelin)-102, Polyethylene glycol [PEG] 2000 dimyristoyl glycerol [DMG], 1,2-distearoyl-sn-glycero-3-phosphocholine [DSPC], and cholesterol.

  7. The Moderna COVID-19 Vaccine and SPIKEVAX (COVID-19 Vaccine, mRNA) contain the following ingredients: messenger ribonucleic acid (mRNA), lipids (SM-102, polyethylene glycol
