Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) Description

BioNTech S.E. and Pfizer, Inc. co-developed the BNT162b2 vaccine to prevent severe COVID-19 caused by the SARS-CoV-2 betacoronavirus. The vaccine is based on BioNTech proprietary messenger RNA (mRNA)

Known globally as Comirnaty, the vaccine is a nucleoside-modified RNA formulated in lipid nanoparticles and encodes an optimized SARS-CoV-2 full-length spike protein antigen. 

Comirnaty contains a molecule with instructions for producing a protein from the SARS-CoV-2 virus. However, Comirnaty does not include the coronavirus itself and cannot cause COVID-19, says the European Medicines Agency (EMA). This Vaccine Information Fact Sheet for Recipients and Caregivers comprises the Fact Sheet for the authorized Pfizer-BioNTech COVID-19 Vaccine. The EMA published a Comirnaty vaccine update EMEA/H/C/005735 on September 24, 2021.

John L. Perez, MD, MBA, MA, Pfizer, Vice President Vaccine Clinical Research & Development, presented 'Efficacy & Safety of BNT162b2 booster' - C4591031 2 month interim analysis during the U.S. CDC vaccine advisory meeting on November 19, 2021. On November 17, 2021, the CDC, in consultation with U.S. FDA, issued emergency use instructions to provide information about the use of the vaccine as an additional primary series dose or as a booster dose in certain individuals who completed vaccination with certain non-FDA-authorized or -approved COVID-19 vaccines. The FDA amended EUA to include a single booster dose that was granted to Pfizer Inc.

The Revised Fact Sheet for Providers includes information about the U.S. FDA-licensed vaccine, COMIRNATY. Please see EUA Fact Sheets at The Comirnaty (Tozinameran) Drugbank Accession Number: DB15696; ChemIDplus 434370509; CAS number: 2417899-77-3; STN: Identifier - Phase 3 clinical trials: NCT04805125NCT04368728NCT04713553NCT04754594 (additional studies are listed at this link).

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) Approvals and Authorizations

The Comirnaty vaccine was issued the first U.S. Food and Drug Administration (FDA) Emergency Use Authorization (EUA) to prevent severe COVID-19 in people 16 years of age and older on December 11, 2020. In addition, on December 31, 2020, the World Health Organization (WHO) issued an Emergency Use Listing (EUL) for the Comirnaty vaccine. On May 10, 2021, the FDA expanded the EUA to include people 12 years old.

The FDA Approved the Comirnaty COVID-19 vaccine on August 23, 2021. The vaccine is also available under FDA EUA, including for individuals 12 through 15 years of age and administering the third dose in specific immunocompromised individuals. The FDA Approval was granted to BioNTech Manufacturing GmbH. The FDA Approved the Comirnaty COVID-19 vaccine for additional people, including individuals 12 through 15 years of age, and for administering the third dose in specific immunocompromised individuals on August 23, 2021. Updated Q&As were issued on August 27, 2021. Then, on October 29, 2021, the FDA extended the authorization to include children 5 through 11 years of age. 

The EMA Approved the Comirnaty vaccine for preventing COVID-19 in people aged 12 years and older on July 29, 2021. The EMA updated EMEA/H/C/005735 on October 15, 2021. The U.K.'s Medicines and Healthcare products Regulatory Agency approved the Comirnaty vaccine for use in booster dosing on September 10, 2021. In addition, Canada issued an Approval for Comirnaty on September 16, 2021.

On September 17, 2021, Pfizer, Inc. executives presented data to the U.S. FDA's Vaccines and Related Biological Products Advisory Committee (VRBPAC) information that confirmed the Comirnaty vaccine's effectiveness is compromised by the SARS-CoV-2 virus variant Delta. As a result, on September 22, 2021, the FDA amended the EUA to allow for the use of a single booster dose for certain people to be administered at least six months after completion of the two-dose primary series. Click here for the Factsheet for Vaccination Providers and here for the Recipients and Caregivers Fact Sheet. The Summary Basis for Regulatory Action 125742/0 was filed with the U.S. on November 8, 2021.

The FDA announced on November 19, 2021, it amended the EUA for Comirnaty authorizing the use of a single booster dose for all individuals 18 years of age and older after completion of primary vaccination with any FDA-authorized or approved COVID-19 vaccine.

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer BNT162b2) History

On July 1, 2020, the manuscript describing the preliminary clinical data for the Comirnaty vaccine became available online for scientific peer-review for potential publication. Pfizer and BioNTech stated on August 5, 2020, they began a Phase 2b/3 safety and efficacy trial and remained on track to seek regulatory review as early as October 2020. On August 20, 2020, a non-peer-reviewed abstract found BNT162b2 was associated with less systemic reactogenicity, particularly in older adults. Pfizer provided an update on September 15, 2020, stating: 'Limited blinded tolerability data from the ongoing Phase 3 trial, confirming the mild to moderate tolerability profile as was observed in Phase 1. 

On December 10, 2020, the NEJM published original research that confirmed a 2-dose regimen of BNT162b2 conferred 95% protection against COVID-19 in persons 16 years of age or older. And, safety over a median of 2 months was similar to that of other viral vaccines. In addition, an early release of the CDC's Morbidity and Mortality Weekly Report published on December 13, 2020, stated 'after a detailed, evidence-based review of all available data, the Advisory Committee on Immunization Practices (ACIP) issued an interim recommendation for the use of the Pfizer-BioNTech COVID-19 vaccine in persons aged ≥16 years for the prevention of COVID-19, reported the ACIP website.

A study published by The Lancet on February 22, 2021, concluded by saying, 'this study demonstrates that the BNT162b2 vaccine effectively prevents both symptomatic and asymptomatic infection in working-age adults. And this cohort was vaccinated when the dominant variant in circulation was B1.1.7 and demonstrated effectiveness against this variant.' However, on July 15, 2021, The Lancet published a study: Spike-antibody waning after the second dose of BNT162b2. Our data suggest waning of S-antibody levels in infection-naive individuals over a 3–10-week period after the second dose of BNT162b2. These data are consistent with the decline in Spike-antibody and neutralizing antibody levels observed after infection, although memory B-cell populations appear to be maintained. As such, the clinical implications of waning antibody levels post-vaccination are not yet clear, and it remains crucial to establish S-antibody thresholds associated with protection against clinical outcomes.

On October 26, 2021, the U.S. FDA vaccine committee met in an open session to discuss a request to amend Pfizer-BioNTech's EUA to administer their COVID-19 mRNA vaccine to children 5 through 11 years old. The docket number is FDA-2021-N-1088. On October 22, 2021, Pfizer published its presentation to the FDA vaccine committee. 

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) Dosage

The Comirnaty Vaccine is offered in various dose regimens, subject to country-based authorizations. After preparation, a single dose is 0.3 mL is recommended for adults and smaller doses for adolescents and children. The Companies disclosed on October 28, 2021, for children 5 to <12 years of age, the pediatric dosage strength is (10 µg) and differs from the (30 µg) dosage strength for individuals 12 years and older. For the pediatric age group (5-11), the CDC authorized the 10-µg dose level in a two-dose regimen administered 21 days apart.

On October 4, 2021, the EMA's human medicines committee (CHMP) concluded that an extra dose of Comirnaty may be given to people with severely weakened immune systems at least 28 days after their second dose. However, there is no direct evidence that is producing antibodies in these patients protected against COVID-19. Therefore, the CHMP also concluded that booster doses (3rd) might be considered at least six months after the second dose for people aged 18 years and older.

The U.K.'s JCVI confirmed on September 14, 2021, 'the JCVI advises a preference for the Pfizer-BioNTech Comirnaty vaccine to be offered as the third booster dose irrespective of which product was used in the primary schedule. And, the JCVI advises that the booster vaccine dose is offered no earlier than six months after completion of the primary 2-dose vaccine course.'

On August 12, 2021, the U.S. FDA amended the EUAs for the Pfizer-BioNTech COVID-19 Vaccine to allow for the use of an additional dose in specific immunocompromised individuals. The CDC's Sara Oliver M.D., MSPH, presented at the ACIP Meeting on August 13, 2021, Considering booster doses of COVID-19 vaccines. Participants in a phase 1 study received a 30-µg booster dose of BNT162b2 8 to 9 months after receiving the second dose. Results from this participant group show that the third dose elicited significantly higher neutralizing antibodies against the initial SARS-CoV-2 coronavirus compared to the levels observed after the two-dose primary series and against the Beta variant and the highly infectious Delta variant. On September 24, 2021, the CDC Director approved delivering a third dose of Comirnaty to most people. The FDA authorized the third dose in October 2021. 

The UK's Joint Committee on Vaccination and Immunisation advised on November 15, 2021, that most people over 16 years should be offered an mRNA booster, 6 months after their second dose, irrespective of the vaccines given for the first and second doses.

On November 30, 2021, a peer-reviewed study funded by the government of Canada found that a longer second dosing interval (42–49 days) resulted in higher spike, receptor binding domain, and spike N terminal domain antibody concentrations.

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) Ingredients

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

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) Side Effects

The U.S. CDC's ACIP committee's presentation slides on August 30, 2021, were published. And again on October 21, 2021, presenting heart-health risks. Hui-Lee Wong, Ph.D., MSc, presented Surveillance Updates of Myocarditis/Pericarditis and mRNA COVID-19 Vaccination in the FDA BEST System during the U.S. FDA's VRBPAC meeting on October 14, 2021. And the CDC meeting on October 21, 2021.

The U.S. CDC published Possible Side Effects of COVID-19 vaccines on March 5, 2021. And, the CDC published 'Understanding Side Effects and Adverse Events.' In addition, on July 6, 2021, the CDC published Use of mRNA COVID-19 Vaccine After Reports of Myocarditis Among Vaccine Recipients: Update from the Advisory Committee on Immunization Practices — United States, June 2021. In addition, the FDA updated its guidance in October 2021.

The journal Rheumatology published a study on April 13, 2021, that concluded by saying, 'Epidemiologic studies on the safety of the mRNA-based COVID-19 vaccines in patients with autoimmune inflammatory rheumatic diseases are needed to clarify the association between the BNT162b2 mRNA vaccination and reactivation of zoster.'

On December 3, 2021, the EMA stated a recent French study shows that, in a period of seven days after the second dose, there were about 0.26 extra cases of myocarditis in 12- to 29-year-old males per 10,000 compared to unexposed persons. In the Nordic study, in a period of 28 days after the second dose, there were 0.57 extra cases of myocarditis in 16- to 24-year-old males per 10,000 compared to unexposed persons. Furthermore, there is currently insufficient evidence of a possible link between Comirnaty and very rare cases of multisystem inflammatory syndrome.

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) SARS-CoV-2 Coronavirus Variants

BioNTech confirmed on November 9, 2021, studies are underway evaluating variant-specific versions of the vaccine to generate data to inform BioNTech and Pfizer’s strategy to address emerging SARS-CoV-2 variants. While to date, there is no clinical data suggesting the need for a variant-specific version of the vaccine, the companies are establishing a preemptive prototype approach to evaluate the development, manufacturing, and regulatory processes for variant-specific vaccines. This prototype approach is aimed to be substantiated by broad clinical data that are being prepared for submission to regulatory authorities.

The NEJM published an ORIGINAL ARTICLE on July 28, 2021, Covid-19 Breakthrough Infections in Vaccinated Health Care Workers. This study based in Israeli found a 2.6% COVID breakthrough reinfection rate of the Alpha variant in health care staff. On August 19, 2021, Oxford University published a study that concluded by saying 'SARS-CoV-2 vaccination still reduces new infections, but the vaccine's effectiveness and attenuation of peak viral burden are reduced with SARS-CoV-2 Delta virus variant.'

Pfizer disclosed in its presentation to the U.S. FDA on September 17, 2021, 'A retrospective cohort study conducted at Kaiser Permanente Southern California suggests that the observed erosion in Cominraty vaccine effectiveness is likely primarily due to waning effectiveness rather than due to Delta variant escaping vaccine protection.

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer BNT162b2) For Children

On November 25, 2021, Pfizer Inc. and BioNTech SE announced that the Committee for Medicinal Products for Human Use of the European Medicines Agency issued a positive opinion on the administration of the COMIRNATY vaccine in children 5 to under 12 years of age. 

The updated findings from the companies’ pivotal Phase 3 trial published on November 22, 2021, show that a two-dose series of the Comirnaty Vaccine (30-µg per dose) was 100% effective against COVID-19, measured seven days through over four months after the second dose.

Isreal's Ministry of Health's Director-General, Prof. Nachman Ash, accepted the recommendation by the Pandemic Response Team on November 15, 2021, and the COVID-19 Vaccination Advisory Board, to vaccinate children aged 5-11.

U.S. CDC Director Rochelle P. Walensky, M.D., M.P.H., endorsed the Advisory Committee on Immunization Practices’ recommendation that children 5 to 11 years old be vaccinated against COVID-19 with the Pfizer-BioNTech pediatric vaccine on November 2, 2021. The CDC's ACIP unanimously voted to support vaccinating children between 5 and 11 years of age on November 2, 2021. 

The FDA's VRBPAC meeting on October 26, 2021, discussed a request to amend Pfizer-BioNTech's EUA for the administration of their COVID-19 mRNA vaccine to children 5 through 11 years of age. Pfizer's presentation was distributed on October 22, 2021. The FDA advisory committee voted in favor of this request. On October 29, 2021, the FDA authorized this EUA extension.

The U.S. CDC reported on October 19, 2021, among hospitalized U.S. patients aged 12–18 years, vaccine effectiveness of 2 doses of Comirnaty vaccine against COVID-19 hospitalization during June–September 2021, was 93% (95% confidence interval = 83%–97%).

On August 4, 2021, the U.K.'s Joint Committee on Vaccination and Immunisation issued an advisory that all 16 and 17-year-olds should receive their first dose of the Pfizer-BioNTech vaccine.

The EMA’s human medicines committee recommended on November 25, 2021, granting an extension of indication for the COVID-19 vaccine Comirnaty to include use in children aged 5 to 11.

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) Indication For Women

On July 8, 2021, the JAMA Oncology published: Serologic Status and Toxic Effects of the SARS-CoV-2 BNT162b2 Vaccine in Patients Undergoing Treatment for Cancer. Conclusions and Relevance - In this cohort study, the SARS-CoV-2 BNT162b2 vaccine appeared safe and achieved satisfactory serologic status in patients with cancer. There was a pronounced lag in antibody production compared with the rate in noncancer controls. However, seroconversion occurred in most patients after the second dose. Future real-world data are warranted to determine the long-term efficacy of the vaccine concerning the type of anticancer treatment.

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) Indication For Multiple Sclerosis Patients

In this study published by the JAMA Network on September 23, 2021, the humoral response against SARS-CoV-2 at one month after mRNA vaccination was appropriate under treatment with cladribine and teriflunomide and diminished/absent under treatment with anti-CD20 therapies and S1P modulators. Delaying anti-CD20 infusions by 3 to 6 months before vaccination could, however, increase the probability of developing appropriate humoral responses, especially in selected clinically and radiologically stable patients. Future studies should aim at investigating antibody dynamics over time, if and how T cell-mediated responses after vaccination are influenced by DMTs, and whether these biological measures actually reflect vaccine efficacy in terms of preventing severe SARS-CoV-2 infection.

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer; BNT162b2) Distribution
