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

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

The Comirnaty mRNA BNT162b2 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 called messenger RNA (mRNA) 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.

This Vaccine Information Fact Sheet for Recipients and Caregivers comprises the Fact Sheet for the authorized Pfizer-BioNTech COVID-19 Vaccine. Also, the Revised Fact Sheet for Providers includes information about the FDA-licensed vaccine, COMIRNATY (COVID-19 Vaccine, mRNA). The European Medicines Agency published a Comirnaty vaccine update EMEA/H/C/005735 on September 24, 2021.

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) for a vaccine to prevent COVID-19 individuals 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. The WHO stated, 'novel Covid-19 mRNA vaccine does not contain the SARS-CoV-2 coronavirus itself and cannot cause COVID-19.'

On May 10, 2021, the FDA's EUA expanded to include people 12 years old. The FDA Approved the Comirnaty (Pfizer-BioNTech) COVID-19 vaccine on August 23, 2021. The vaccine also continues to be available under emergency use authorization (EUA), including for individuals 12 through 15 years of age and for administering the third dose in specific immunocompromised individuals. The FDA Approval was granted to BioNTech Manufacturing GmbH. The U.S. 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, and published updated Q&As for Comirnaty on August 27, 2021. The European Medicines Agency (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 Pfizer/BioNTech (Comirnaty) vaccine for use in booster dosing on September 10, 2021. In addition, health Canada issued an Approval for the Pfizer-BioNTech Comirnaty COVID-19 vaccine 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 for the Pfizer-BioNTech COVID-19 Vaccine 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.

Biopharmaceutical New Technologies (BioNTech S.E.) is the Marketing Authorization Holder in the United States, the European Union, and the United Kingdom, and the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer), Canada, and other countries. The amendment to the FDA's EUA to include a single booster dose was granted to Pfizer Inc.

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

On July 1, 2020, the manuscript describing the preliminary clinical data for BNT162 was available online for scientific peer-review for potential publication. On July 27, 2020, the Companies advanced nucleoside-modRNA candidate BNT162b2, which encodes an optimized SARS-CoV-2 full-length spike glycoprotein, at a 30µg dose level, in a 2-dose regimen, into Phase 2/3 study of up to 30,000 participants aged 18 – 85 years, and is expected to include approximately 120 sites globally.

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 September 12, 2020, the companies announced they have submitted a request to the U.S. FDA to expand the enrollment of their Phase 3 pivotal COVID-19 vaccine trial to up to approximately 44,000 participants, which increases the study's population diversity, and include adolescents as young as 16 years of age and people with chronic, stable HIV, Hepatitis C, or Hepatitis B infection. In addition, on September 17, 2020, Pfizer's overview document for the 'Phase 1/2/3 Study to Evaluate the Safety, Tolerability, Immunogenicity, and Efficacy of RNA Vaccine Candidates Against COVID-19 in Healthy Individuals' became available.

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 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.

The companies submitted Phase 1 data to the U.S. FDA on August 16, 2021, to support evaluating a third or booster dose of the Comirnaty (BNT162b2) vaccine for future licensure. In addition, the Lancet published a Pfizer-funded study on October 4, 2021, showing Comirnaty was 88% effective in the first month after complete 2-dose vaccination but dropped to 47% effectiveness at about six months. Thus, the reduction in vaccine effectiveness against SARS-CoV-2 infections is probably due to waning immunity over time rather than the delta variant escaping vaccine protection.

On October 26, 2021, the U.S. FDA vaccine committee will meet 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. 

Biopharmaceutical New Technologies is an immunotherapy company pioneering novel therapies for cancer and other serious diseases. The Company published an update on December 2, 2020. New York-based Pfizer's corporation information is updated at this link.

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

The Comirnaty Pfizer-BioNTech COVID-19 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.

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 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 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.

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

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. And each dose of the Pfizer-BioNTech COVID-19 Vaccine 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.

The Pfizer-BioNTech COVID-19 Vaccine does not contain preservatives. In addition, the vial stoppers are not made with natural rubber latex. The U.S. CDC publishes 'Common Ingredients in U.S. Licensed Vaccines.'

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

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, 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.'

In addition, on July 6, 2021, the U.S. 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. Health Canada updated the product information for the Pfizer-BioNTech COVID-19 vaccine on August 6, 2021, to describe infrequent reports of Bell's Palsy following vaccination.

The NEJM journal published a study based on data from Israel on August 25, 2021, that concluded 'the Comirnaty vaccine was associated with an excess risk of myocarditis 1 to 5 events per 100,000 persons (risk ratio, 3.24; 95% confidence interval [CI], 1.55 to 12.44; risk difference, 2.7 events per 100,000 persons; 95% CI, 1.0 to 4.6). Additionally, the risk of this potentially serious adverse event and many other serious adverse events was substantially increased after SARS-CoV-2 infection. 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 in October 14, 2021. And the CDC meeting on October 21, 2021.

The EMA issued a Safety Update on October 6, 2021, reporting 361,767 suspected side effects in the EU/EEA. In addition, on October 13, 2021, Parsonage-Turner syndrome was highlighted as a potential adverse effect of mRNA COVID vaccines in a recent pharmacovigilance monitoring report from the French National Agency for the Safety of Medicines and Health Products.

The companies announced additional Side Effect considerations on October 28, 2021.

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

On June 3, 2021, the Lancet published a research letter that stated: 'Levels of antibodies in the blood of vaccinated people that can recognize and fight the new SARS-CoV-2 Delta variant first discovered in India (B.1.617.2) are on average lower than those against previously circulating variants in the U.K., according to new laboratory data from the Francis Crick Institute and the National Institute for Health Research UCLH Biomedical Research Centre.'

The journal Nature published an article on June 10, 2021: BNT162b2-elicited neutralization of B.1.617 and other SARS-CoV-2 variants.

A new analysis by PHE published on June 14, 2021, shows the Pfizer-BioNTech vaccine is 96% effective against hospital admission with the Delta (B.1.617.2) variant.

On July 4, 2021, Ynet news reported the Israeli health ministry announced from June 6 to July 2, 2021, the vaccine demonstrated 64% efficacy at preventing cases and 94% effectiveness at preventing hospitalizations. And, Politico reported Public Health England said data published on July 2, 2021, suggests vaccine effectiveness against symptomatic disease from one dose of the vaccines in use provides between 55 to 70 percent efficacy. Data on two doses indicates the efficacy of around 65 to 90%.

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.'

A non-peer-review study conducted by researchers in Japan reported on August 23, 2021, 'although Pfizer-BioNTech BNT162b2-immune sera neutralized the Delta variant, when four common mutations were introduced into the receptor-binding domain of the Delta variant (Delta 4+), some BNT162b2-immune sera lost neutralizing activity and enhanced the infectivity.'

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 escaping vaccine protection.

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

Children: Pfizer confirmed on March 25, 2021, they have dosed the first healthy children in a global Phase 1/2/3 continuous study to evaluate further the safety, tolerability, and immunogenicity of the Pfizer-BioNTech COVID-19 vaccine in 4,644 children between the ages of 11 years to 6 months.

In May 2021, the UAE Ministry of Health and Prevention approved the emergency local use of Pfizer vaccine for children between the ages of 12 and15 following clinical trials and a strict assessment. However, on June 1, 2021, the AAP published an article that found boys aged 14 to 19 received Pfizer vaccinations in April or May 2021 and developed chest pain within a few days. In addition, heart imaging tests showed a type of heart muscle inflammation called myocarditis.

On June 10, 2021, Reuters reported Germany's STIKO vaccine advisory committee recommended that only children and adolescents with pre-existing conditions be given the Pfizer - BioNTech vaccine. Additionally, STIKO said that doctors were allowed to give the shot if the individual accepted the risk. The U.K.'s JCVI announced on July 19, 2021; it advises that children at increased risk of severe COVID-19 are offered the Pfizer-BioNTech vaccine. This includes children aged 12 to 15 with severe neurodisabilities, Down's syndrome, immunosuppression, and multiple or severe learning disabilities. The JCVI also recommends that children and young people aged 12 to 17 who live with an immunosuppressed person be offered the vaccine. 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. On July 22, 2021, the Australian Therapeutic Goods Administration granted Pfizer Australia Pty Ltd provisional approval for its COVID-19 vaccine, COMIRNATY, in individuals aged 12 years and older.

The U.K.'s JCVI published an update on September 2, 2021, 'Overall, the committee is of the opinion that the benefits from vaccination are marginally greater than the potential known harms (tables 1 to 4) but acknowledges that there is considerable uncertainty regarding the magnitude of the potential harms.' So then, the chief medical officers of England, Scotland, Wales, and Northern Ireland recommended on September 13, 2021, that children aged 12 to 15 be given a single dose of the Pfizer/BioNTech Comirnaty vaccine. In an evaluation conducted in Israel, among individuals ≥16 years of age, BNT162b2 effectiveness against SARS‑CoV-2 infection was only 39.0% (95% CI: 9.0%, 59.0%) and against symptomatic COVID-19 was 40.5% (95% CI: 8.7%, 61.2%) between 20 June 2021 and 17 July 2021.

During the CDC's ACIP meeting on June 23, 2021, Tom Shimabukuro, MD, MPH, MBA Vaccine Safety Team, presented 'Early safety data of Pfizer-BioNTech vaccination in persons aged 12–15 years old.' In addition, Dr. Rochelle P. Walensky announced her endorsement of the CDC Advisory Committee on Immunization Practices' recommendation for using Pfizer-BioNTech's licensed vaccine for people 16 and older on August 30, 2021.

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

The FDA's VRBPAC meeting on October 26, 2021, intends to discuss 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. 

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

The journal Nature Medicines published results from a new study on September 7, 2021: Effectiveness of the BNT162b2 mRNA COVID-19 vaccine in pregnancy. In summary, the BNT162b2 mRNA vaccine was estimated to have high vaccine effectiveness in pregnant women, similar to the general population's effectiveness.

As of October 22, 2021, thirty-three countries do not recommend pregnant women receive a COVID-19 vaccine, according to the global Maternal Immunization Tracker, produced by Johns Hopkins University.

Comirnaty COVID-19 Vaccine (BioNTech - Pfizer BNT162b2) Indication For Cancer Patients

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.

The National Comprehensive Cancer Network® (NCCN®) announced on August 30, 2021, enhancements to the NCCN: Cancer and COVID-19 Vaccination guidance. The fourth version incorporates the latest data and recent FDA and CDC approvals regarding a third mRNA vaccine dose for immunocompromised people.

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

The Companies disclosed on October 28, 2021, they have shipped more than 1.8 billion COVID-19 vaccine doses to 149 countries and territories.
