2.2 Administration Information
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. The vaccine will be a white to off-white suspension. Do not administer if vaccine is discolored or contains particulate matter.
Administer the 0.3 mL dose intramuscularly immediately after preparation. For the prefilled syringe, administer the entire volume to deliver a single 0.3 mL dose.
2.3 Vaccination Schedule
COMIRNATY is administered as a single dose for individuals 12 years of age and older.
For individuals previously vaccinated with any COVID-19 vaccine, administer the dose of COMIRNATY at least 2 months after the last dose of COVID-19 vaccine.
3 DOSAGE FORMS AND STRENGTHS
COMIRNATY is a suspension for injection. A single dose is 0.3 mL.
4 CONTRAINDICATIONS
Do not administer COMIRNATY to individuals with known history of a severe allergic reaction (e.g., anaphylaxis) to any component of COMIRNATY [see Description (11)] or to individuals who had a severe allergic reaction (e.g., anaphylaxis) following a previous dose of a Pfizer-BioNTech COVID-19 vaccine.
5 WARNINGS AND PRECAUTIONS
5.1 Management of Acute Allergic Reactions
Appropriate medical treatment used to manage immediate allergic reactions must be immediately available in the event an acute anaphylactic reaction occurs following administration of COMIRNATY.
5.2 Myocarditis and Pericarditis
Postmarketing data with authorized or approved mRNA COVID-19 vaccines demonstrate increased risks of myocarditis and pericarditis, particularly within the first week following vaccination. For COMIRNATY, the observed risk is highest in males 12 through 17 years of age. Although some cases required intensive care support, available data from short-term follow-up suggest that most individuals have had resolution of symptoms with conservative management. Information is not yet available about potential long-term sequelae.
The Centers for Disease Control and Prevention (CDC) has published considerations related to myocarditis and pericarditis after vaccination, including for vaccination of individuals with a history of myocarditis or pericarditis (https://www.cdc.gov/vaccines/covid-19/clinical-considerations/myocarditis.html).
5.3 Syncope
Syncope (fainting) may occur in association with administration of injectable vaccines, including COMIRNATY. Procedures should be in place to avoid injury from fainting.
5.4 Altered Immunocompetence
Immunocompromised persons, including individuals receiving immunosuppressant therapy, may have a diminished immune response to COMIRNATY [see Use in Specific Populations (8.6)].
5.5 Limitation of Effectiveness
COMIRNATY may not protect all vaccine recipients.
6 ADVERSE REACTIONS
An overview of clinical studies contributing to the safety assessment of COMIRNATY is provided in Table 1. Participants in these clinical studies received a 2-dose series, 3 weeks apart (referred to as a primary series) and subsequent doses referred to as booster doses.
