Multiple Dose Vial – Six Doses

After dilution, vials of Pfizer-BioNTech COVID-19 Vaccine contain six doses of 0.3 mL of vaccine. Low dead-volume syringes and/or needles can be used to extract six doses from a single vial. If standard syringes and needles are used, there may not be sufficient volume to extract a sixth dose from a single vial. Irrespective of the type of syringe and needle:

Description

Each dose of the Pfizer-BioNTech COVID-19 Vaccine contains 30 mcg of a nucleoside-modified messenger RNA (modRNA) encoding the viral spike (S) glycoprotein of SARS-CoV-2.

It also includes the following ingredients: lipids (0.43 mg (4-hydroxybutyl)azanediyl)bis(hexane-6,1-diyl)bis(2-hexyldecanoate), 0.05 mg 2[(polyethylene glycol)-2000]-N,N-ditetradecylacetamide, 0.09 mg 1,2-distearoyl-sn-glycero-3-phosphocholine, and 0.2 mg cholesterol), 0.01 mg potassium chloride, 0.01 mg monobasic potassium phosphate, 0.36 mg sodium chloride, 0.07 mg dibasic sodium phosphate dihydrate, and 6 mg sucrose. The diluent (0.9% Sodium Chloride Injection, USP) contributes an additional 2.16 mg sodium chloride per dose.

Dosing and Schedule

The Pfizer-BioNTech COVID-19 Vaccination is administered intramuscularly as a series of 2 doses (0.3 mL each) 3 weeks apart.

There are no data available on the interchangeability of the Pfizer-BioNTech COVID-19 Vaccine with other COVID-19 vaccines to complete the vaccination series. Individuals who have received one dose of Pfizer-BioNTech COVID-19 Vaccine should receive a second dose of Pfizer-BioNTech COVID-19 Vaccine to complete the vaccination series.

Dose Preparation

The Pfizer‑BioNTech COVID-19 Vaccine Multiple Dose Vial contains a frozen suspension that does not contain preservative and must be thawed and diluted prior to administration
Vials may be thawed in the refrigerator or at room temperature [up to 25°C (77°F)]
Prior to dilution, the thawed suspension may contain white to off-white opaque amorphous particles
The contents of the vial must be diluted with 1.8 mL of sterile 0.9% Sodium Chloride Injection, USP to form the Pfizer-BioNTech COVID-19 Vaccine
After dilution, the vial contains 6 doses of 0.3 mL of vaccine
0.9% Sodium Chloride Injection, USP is not packaged with the vaccine and must be sourced separately. Do not use bacteriostatic 0.9% Sodium Chloride Injection or any other diluent. Do not add more than 1.8 mL of diluent. Please see the Q&A section for more information on dose preparation
After dilution, the vaccine will be an off-white suspension. Inspect vials to confirm there are no particulates and no discoloration is observed
Strict adherence to aseptic techniques must be followed

Thawing Prior to Dilution
	Thaw vial(s) of Pfizer-BioNTech COVID-19 Vaccine before use either by: Allowing vial(s) to thaw in the refrigerator [2°C to 8°C (35°F to 46°F)]. A carton of vials may take up to 3 hours to thaw, and thawed vials can be stored in the refrigerator for up to five days (120 hours) Allowing vial(s) to sit at room temperature [up to 25°C (77°F)] for 30 minutes Using either thawing method, vials must reach room temperature before dilution and must be diluted within 2 hours
	Invert Before dilution invert vaccine vial gently 10 times Do not shake Inspect the liquid in the vial prior to dilution. The liquid is a white to off-white suspension and may contain white to off-white opaque amorphous particles Do not use if liquid is discolored or if other particles are observed
	Dilute Obtain sterile 0.9% Sodium Chloride Injection, USP. Use only this as the diluent Using aseptic technique, withdraw 1.8 mL of diluent into a transfer syringe (21-gauge or narrower needle) Cleanse the vaccine vial stopper with a single-use antiseptic swab Add 1.8 mL of 0.9% Sodium Chloride Injection, USP into the vaccine vial
	Equalize Equalize vial pressure before removing the needle from the vial by withdrawing 1.8 mL of air into the empty diluent syringe
	Invert Gently invert the vial containing the Pfizer-BioNTech COVID-19 Vaccine 10 times to mix Do not shake Inspect the vaccine in the vial The vaccine will be an off-white suspension. Do not use if vaccine is discolored or contains particulate matter
	Record and Store Record the date and time of dilution on the Pfizer-BioNTech COVID-19 Vaccine vial label Store between 2°C to 25°C (35°F to 77°F) Discard any unused vaccine 6 hours after dilution

Preparation of Individual 0.3 mL Doses of Pfizer-BioNTech COVID-19 Vaccine
	Cleanse Using aseptic technique, cleanse the vial stopper with a single-use antiseptic swab, and withdraw 0.3 mL of the Pfizer-BioNTech COVID-19 Vaccine preferentially using low dead-volume syringes and/or needles Each dose must contain 0.3 mL of vaccine If the amount of vaccine remaining in the vial cannot provide a full dose of 0.3 mL, discard the vial and any excess volume Administer immediately

Preparation of Individual 0.3 mL Doses of Pfizer-BioNTech COVID-19 Vaccine

Cleanse

Using aseptic technique, cleanse the vial stopper with a single-use antiseptic swab, and withdraw 0.3 mL of the Pfizer-BioNTech COVID-19 Vaccine preferentially using low dead-volume syringes and/or needles
Each dose must contain 0.3 mL of vaccine
If the amount of vaccine remaining in the vial cannot provide a full dose of 0.3 mL, discard the vial and any excess volume
Administer immediately

Administration

Visually inspect each dose in the dosing syringe prior to administration. The vaccine will be an off-white suspension. During the visual inspection,

verify the final dosing volume of 0.3 mL
confirm there are no particulates and that no discoloration is observed
do not administer if vaccine is discolored or contains particulate matter

Administer the Pfizer-BioNTech COVID-19 Vaccine intramuscularly.

Review the Product Safety Data Sheet for the vaccine. In the event of vial breakage, damage, or leakage, to prevent cuts and exposure to the vaccine, do not handle the vial with bare hands; wear protective gloves. Remove broken glass with forceps, tongs, or other appropriate tools. Dispose of the vial and vial pieces in a medical sharps container.
