Pfizer-BioNTech COVID-19 Vaccine Ingredients
All COVID-19 vaccine ingredients are safe. Nearly all of the ingredients in COVID-19 vaccines are ingredients found in many foods – fats, sugars, and salts. The Pfizer-BioNTech COVID-19 vaccine also contains a harmless piece of messenger RNA (mRNA). The COVID-19 mRNA teaches cells in the body how to create an immune response to the virus that causes COVID-19. This response helps protect you from getting sick with COVID-19 in the future. After the body produces an immune response, it discards all of the vaccine ingredients, just as it would discard any substance that cells no longer need. This process is a part of normal body functioning.
All COVID-19 vaccines are manufactured with as few ingredients as possible and with very small amounts of each ingredient. Each ingredient in the vaccine serves a specific purpose as seen in the table below.
Pfizer-BioNTech has updated the formulation of the Pfizer-BioNTech COVID-19 vaccine. The updated formulation has the same active ingredients as the previous formulation but uses different stabilizers (ingredients that help keep the vaccine molecules stable while the vaccine is manufactured, frozen, shipped, and stored). These changes allow for easier shipping and longer storage of vaccines at refrigerator temperatures. This will help improve access to vaccines for people who need them and will decrease waste.
Previous formulation
The previous formulation for people ages 12 years and older is no longer being distributed, and once the doses of that formulation have been used, only the updated formulation will be available. Both formulations can be used interchangeably without any safety or effectiveness concerns. Check with your healthcare provider about which formulation they carry if you are concerned about any of the ingredients.
Administration Overview
Before administering vaccine, screen recipients for contraindications and precautions using the Prevaccination Checklist below, even if the recipient has received previous doses. The recipient’s health condition or recommendations for vaccination may change from one visit to the next.
Prepare and administer the vaccine following manufacturer’s guidance which is outlined in CDC’s Preparation and Administration Summary below.
Follow the COVID-19 vaccination schedule (below) based on age and medical condition.
Storage and Handling Overview
- Ensure staff are knowledgeable about correct storage of the vaccines.
- Follow CDC’s guidance for storage units and temperature monitoring.
- Vaccines and diluents must be unpacked, stored at recommended temperatures, and documented immediately after arrival.
Clinical care
Vaccinating Homebound Persons
Introduction
COVID-19 vaccination of homebound persons presents unique challenges to ensure the appropriate vaccine storage temperatures, handling, and administration to ensure safe and effective vaccination. Homebound personsexternal icon include those that need the help of another person or medical equipment such as crutches, a walker, or a wheelchair to leave their home, or their medical provider believes that their health or illness could get worse if they leave their home, and they typically do not leave their home.
The information below provides guidance on management of vaccines and vaccination for persons vaccinated at home or in small group settings (e.g., residential facilities, group homes).
Jurisdictions: Vaccinating Older Adults and People with Disabilities
Many older adults and people with disabilities may have substantial challenges accessing COVID-19 vaccination services and warrant specific considerations to support equitable vaccine access. This page summarizes what jurisdictions should consider when planning to vaccinate older adults and people with disabilities living in the community. It also provides considerations to help jurisdictions ensure equal opportunities for vaccination of these populations.
Older adults and people with disabilities who may need additional support to be vaccinated include those who are:
Without
- Transportation or unable to travel
- Family or community support to help them find out about vaccines
- Access to the internet or unable to use online scheduling systems
- Not native English speakers
- Considered to have lower health literacy
- In an ethnic, racial, or other group at higher risk for severe illness from COVID-19
Living
- in remote, rural, or tribal areas
- with cognitive impairment or decline
- with mobility challenges, vision or hearing loss, or other disabilities
- in congregate or crowded settings, such as group homes and independent living facilities for older adults.
