Comirnaty Vaccine (BNT162b2) Description

BioNTech and Pfizer developed the Comirnaty (BNT162b2) vaccine to prevent severe COVID-19 disease caused by the SARS-CoV-2 coronavirus. Comirnaty is a nucleoside-modified RNA formulated in lipid nanoparticles and encodes an optimized SARS-CoV-2 full-length spike protein antigen.

The Comirnaty (BNT162b2) (Tozinameran) mRNA vaccine was issued the first U.S. FDA emergency use authorization for a vaccine to prevent COVID-19 individuals 16 years of age and older on December 11, 2020. However, the Pfizer-BioNTech COVID-19 vaccine has not been Approved or Licensed by the U.S. FDA.

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 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. This study was last updated on September 4, 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. In the blinded data presented, 50% of trial participants received a placebo, and 50% received BNT162b2.'

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.

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 November 9, 2020, the companies issued a press statement that said 'the vaccine candidate was found to be more than 90% effective in preventing COVID-19 in (94) participants without evidence of prior SARS-CoV-2 infection the first interim efficacy analysis. The phase 3 clinical trial will continue through to final analysis at 164 confirmed cases to collect further data and characterize the vaccine candidate’s performance against other study endpoints.'

“The first interim analysis of our global Phase 3 study provides evidence that a vaccine may effectively prevent COVID-19. This is a victory for innovation, science, and a global collaborative effort,” said Prof. Ugur Sahin, BioNTech's CEO.

And on November 18, 2020, Pfizer and BioNTech announced that, after conducting the final efficacy analysis in their ongoing Phase 3 study, their vaccine candidate, BNT162b2, met all of the study’s primary efficacy endpoints.

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.

An early release of the CDC's Morbidity and Mortality Weekly Report published on December 13, 2020, stated 'after an explicit, 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. And, the ACIP will continue to review additional data as they become available; updates to recommendations or clinical considerations will be posted on the ACIP website.'

On December 14, 2020, the companies announced additional data on neutralizing antibody and T cell responses from the Phase 1/2 trial with BNT162b2 conducted in Germany. The study results demonstrate that BNT162b2 elicits a combined adaptive humoral and cellular immune response against SARS-CoV-2 and provide insights into the composite nature of BNT162b2-induced T cell immunity. The results were published on the preprint server MedRxiv.

Ugur Sahin, M.D., CEO and Co-founder of BioNTech, stated in a press release: “While there is a broad consensus that vaccines should induce antibody responses against the virus, experiences from the prior SARS pandemic indicate that CD8+ T cell responses may be of critical importance to achieve long-term protection.”

BioNTech will provide its partners' clinical supply of the vaccine from its GMP-certified mRNA manufacturing facilities in Europe during the clinical development stage.

BioNTech is also collaborating with Fosun Pharma to develop BNT162 in China. On March 13, 2020, Fosun Pharma became the strategic partner of BioNTech in China, jointly developing and commercializing vaccine products for COVID-19 based on its proprietary mRNA technology platform in Mainland China, Hong Kong, the Macau Special Administration Region, and the Taiwan Region.

Biopharmaceutical New Technologies is an immunotherapy company pioneering novel therapies for cancer and other serious diseases. The company published a corporate update on December 2, 2020.

Comiranty Vaccine (BNT162b2) Side Effects

Summary of safety data: In clinical trials, reactogenicity symptoms (side effects that happen within 7 days of getting vaccinated were common but were mostly mild to moderate. Side effects, such as fever, chills, tiredness, and headache, were more common throughout the body after the second vaccine dose. Most side effects were mild to moderate. However, a small number of people had severe side effects—defined as side effects affecting a person’s ability to do daily activities.

The U.S. CDC publishes 'Understanding Side Effects and Adverse Events.'

Anaphylaxis, an acute and potentially life-threatening allergic reaction, has been reported following the COVID-19 vaccination. Detailed information on CDC recommendations for vaccination, including contraindications and precautions to vaccination, can be found in the Clinical Considerations for the use of mRNA COVID-19 Vaccines Currently Authorized in the USA.

Comirnaty Vaccine (BNT162b2) Coronavirus Variants

A non-peer-reviewed study published on January 19, 2021, investigated SARS-CoV-2-S pseudoviruses bearing either the Wuhan reference strain or the B.1.1.7 lineage spike protein with sera of 16 participants in a previously reported trial with the COVID-19 vaccine BNT162b2. The vaccine's immune sera had equivalent neutralizing titers to both variants. Together with the combined immunity involving humoral and cellular effectors induced by this vaccine, these data make it unlikely that the B.1.1.7 lineage will escape BNT162b2-mediated protection.

Comirnaty Vaccine (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. The vial stoppers are not made with natural rubber latex.

The U.S. CDC publishes 'Common Ingredients in U.S. Licensed Vaccines.'

Comirnaty Vaccine (BNT162b2) Distribution

On January 8, 2021, the EMA’s Human Medicines Committee recommended updating the product information for Comirnaty to clarify that each vial contains 6 doses of the vaccine. To extract six doses from a single vial, low dead-volume syringes and/or needles should be used. The low dead-volume syringe and needle combination should have a dead volume of no more than 35 microliters. If standard syringes and needles are used, there may not be enough of the vaccine to extract the sixth dose from a vial if the amount of vaccine remaining in the vial after the fifth dose cannot provide a full dose (0.3 ml). Further information on all the steps for using Comirnaty is available in the EMA's updated product information.

As of December 20, 2020, the companies stated, 'the vaccine has been authorized or approved for emergency use in more than 15 countries.'

On July 31, 2020, the companies agreed to supply 120 million vaccine doses to Japan in the first half of 2021, subject to regulatory approval.

And on August 9, 2020, the companies finalized discussions to supply European countries with 200 million doses and an option to purchase additional 100 million doses, with deliveries starting by the end of 2020, subject to regulatory approval. In case safety and efficacy studies are successful and the vaccine receives regulatory approval, the companies are expecting to manufacture up to 100 million doses by the end of 2020 and potentially more than 1.3 billion vaccine doses by the end of 2021.

On August 27, 2020, BioNTech SE and Shanghai Fosun Pharmaceutical Co. announced an intended collaboration to supply 10 million doses of their BNT162 mRNA-based vaccine to Hong Kong (Special Administrative Region of China, SAR) and Macao (SAR).

On November 3, 2020, Fosun’s Chief Medical Officer Hui Aimin told Reuters in an interview 'they could seek emergency use authorization in China for BNT162b2. Hui said Fosun was applying for a bridge study for BNT162b2, designed to evaluate whether the large trial data gathered overseas could be extrapolated to the populace of China.'

On November 10, 2020, the companies disclosed an agreement with the European Union (EU) to deliver 200 million vaccine doses, with an option to purchase an additional 100 million doses. BioNTech’s manufacturing sites in Germany and Pfizer’s manufacturing site in Belgium will produce the vaccine supply for the EU. Based on current projections, the companies expect to produce globally up to 1.3 billion doses in 2021.

Pfizer announced a pilot delivery program in four US states; Rhode Island, Texas, New Mexico, and Tennessee. “We are hopeful that results from this vaccine delivery pilot will serve as the model for other U.S. states and international governments, as they prepare to implement effective COVID-19 vaccine programs,” reported Reuters on November 16, 2020.

The UK announced the first Emergency Use Authorization following a worldwide Phase 3 trial of a vaccine to help fight the pandemic on December 2, 2020. Pfizer and BioNTech anticipate further regulatory decisions across the globe in the coming days and weeks and are ready to deliver vaccine doses following potential regulatory authorizations or approvals.

The Honourable Anita Anand, Minister of Public Services and Procurement announced on December 7, 2020, Canada will receive up to 249,000 doses of the Pfizer-BioNTech COVID-19 vaccine in December 2020, contingent on Health Canada authorization of the vaccine. These doses are part of the up to 76 million doses Canada has secured through its existing agreement with Pfizer. On December 9, 2020, Health Canada issued authorization. 

The US government issued distribution authorization on December 11, 2020.

Prime Minister Lee Hsien Loong announced on December 14, 2020, the city-state of Singapore would receive its first batch of the Pfizer-BioNTech coronavirus vaccine by the end of December 2020 and plans to offer it on a free and voluntary basis to the entire population before the second half of 2021.

On December 22, 2020, Malaysia announced it would begin administering Pfizer's Covid-19 vaccine as early as February 2021. The government will also procure enough vaccines to cover more than 80% of the population.

On December 23, 2020, the U.S. government announced it would purchase an additional 100 million doses of the Pfizer/BioNTech COVID-19 vaccine.

BioNTech announced on December 29, 2020, the European Union ordered 100 million additional doses of COMIRNATY bringing total doses to 300 million for EU member states. All 300 million doses are expected to be delivered before 2022.

Comirnaty Vaccine (BNT162b2) Cold Storage

The BNT162b2 vaccine candidate needs to be stored and transported at ultracold temperatures below −70 °C (−94 °F) since the vaccine degrades within 5 days when thawed, says the company.

Failure to store and handle vaccines properly can reduce vaccine potency, resulting in inadequate immune responses in patients and poor protection against disease because the vaccines they received may have been compromised, said the U.S. CDC in 2018.

The Pfizer-BioNTech COVID-19 Vaccine Multiple Dose Vial contains a frozen suspension that does not contain preservatives and must be thawed and diluted before administration. • Vials may be thawed in the refrigerator [2ºC to 8ºC (35ºF to 46ºF)] or at room temperature [up to 25ºC (77ºF).

Comirnaty Vaccine (BNT162b2) Indication

BNT162 is an experimental vaccine candidate that intends to prevent COVID-19 disease in humans aged 16-85. Do not administer Pfizer-BioNTech COVID-19 Vaccine to individuals with a known history of a severe allergic reaction (e.g., anaphylaxis) to any component Pfizer-BioNTech COVID-19 Vaccine.

No pediatric, oncology, or pregnancy vaccine efficacy data has been disclosed. Religious considerations, such as Kosher or Halal, are pending.

Data are not available to assess Pfizer-BioNTech COVID-19 Vaccine's effects on the breastfed infant or milk production/excretion.

On December 9, 2020, the UK's NHS issued an advisory regarding a potential risk for those with severe allergies. The NHS stated, 'the COVID-19 mRNA Vaccine BNT162b2 is not recommended during pregnancy. For women of childbearing age, pregnancy should be excluded before vaccination. Also, women of childbearing age should be advised to avoid pregnancy for at least 2-months after their second dose. Furthermore, risks are unknown whether COVID-19 mRNA Vaccine BNT162b2 is excreted in human milk. A risk to the newborns/infants cannot be excluded. COVID-19 mRNA Vaccine BNT162b2 should not be used during breast-feeding.'

However, on December 10, 2020, the ACOG 'urged the CDC's ACIP committee to include pregnant and lactating individuals in its guidance, providing a permissive recommendation based on an appropriate discussion of risks and benefits between clinicians and pregnant and lactating patients.

Comirnaty Vaccine (BNT162b2) Dosage

The Pfizer-BioNTech COVID-19 Vaccine is administered intramuscularly as a series of two doses (0.3 mL each) three weeks apart.

There are no data to assess the Pfizer-BioNTech COVID-19 Vaccine administration with other vaccines.

Older adults will only be immunized with a given dose level of a vaccine candidate once testing that candidate and dose level in younger adults has provided initial evidence of safety and immunogenicity. Subjects with a higher risk for a severe COVID-19 infection will be included in the second part of the study.

The dose-escalation portion of the study, healthy adults 18–55 and 65–85 years of age were randomized in an ongoing, placebo-controlled, observer-blinded dose-escalation study to receive 2 doses at 21-day intervals of placebo or either of 2 lipid nanoparticle–formulated, nucleoside-modified RNA vaccine candidates: BNT162b1, which encodes a secreted trimerized SARS-CoV-2 receptor-binding domain, or BNT162b2, which encodes a prefusion stabilized membrane-anchored SARS-CoV-2 full-length spike. In each of 13 groups of 15 participants, 12 received a vaccine, and 3 received a placebo.

Groups were distinguished by a vaccine candidate, age of the participant, and vaccine dose level. Interim safety and immunogenicity data of BNT162b1 in younger adults have been reported previously from US and German trials. We now present additional safety and immunogenicity data from the Phase 1 trial that supported the vaccine candidate's selection advanced to a pivotal Phase 2/3 safety and efficacy evaluation.

Comirnaty Vaccine (BNT162b2) News

January 15, 2021 - Pfizer and BioNTech announced they had developed a plan that will allow the scale-up of manufacturing capacities in Europe and delivers significantly more doses in the second quarter. To accomplish this, certain modifications of production processes are required now.  As a result, our facility in Puurs, Belgium, will temporarily reduce the number of doses delivered in the upcoming week. We will be back to the original schedule of deliveries to the European Union beginning the week of January 25, with increased delivery beginning the week of February 15, resulting in our ability to deliver the fully committed quantity of vaccine doses in the first quarter and significantly more in the second quarter.  The companies will inform the European Commission, EU member states, and other countries impacted by the updated delivery schedule changes.

January 13, 2021 - The Lancet published 'European Medicines Agency's EU conditional marketing authorizations for COVID-19 vaccines.' Few medicines are awaited as eagerly as COVID-19 vaccines. Extraordinary efforts by scientists, regulators, and developers enabled the European Medicines Agency (EMA) to recommend the first EU conditional marketing authorization (CMA) for the BioNTech COVID-19 mRNA vaccine (nucleoside-modified) BNT162b2 (Comirnaty) some 9 months after the COVID-19 pandemic was declared. On Dec 21, 2020, the European Commission granted CMA, following the EMA's positive opinion, to BNT162b2 for active immunization of individuals aged 16 years and older to prevent COVID-19. The first EU marketing authorizations for COVID-19 vaccines offer hope to control the pandemic and provide proof of concept for a new approach to vaccine development in response to future emerging health threats.

January 12, 2021 - The Times of Israel reported initial data shows that Pfizer’s coronavirus vaccine curbs coronavirus infections by some 50% 14 days after the first vaccination is administered, said Sharon Alroy-Preis, head of the Health Ministry’s public health department.

January 8, 2021 - Statement regarding European Commission’s Proposal to Purchase Additional Doses of BioNTech-Pfizer Vaccine - The amendment being discussed is for a firm order for an additional 200 million doses of COMIRNATY® to be supplied to the 27 EU member states, with an option for the EC to request an additional 100 million doses.  This amendment would add to the 300 million doses that have already been committed to the EU through 2021 under the original supply agreement signed last year. The additional doses would be delivered starting in the second quarter of 2021. This would bring the total number of doses to be delivered to EU member states by the end of 2021 to 500 million doses, with the potential for an additional 100 million if the option is exercised.

January 8, 2021 - BioNTech SE announced results from an in vitro study conducted by Pfizer and the University of Texas Medical Branch that shows the antibodies from people who have received the Pfizer-BioNTech COVID-19 vaccine effectively neutralize SARS-CoV-2 with a key mutation that is also found in two highly transmissible strains. While the virus tested in this experiment did not include the full set of spike mutations found on the rapidly spreading strains in the U.K. or South Africa, neutralization of the virus with the N501Y mutation by the Pfizer-BioNTech vaccine-elicited human sera is consistent with preserved neutralization of a panel of 15 pseudoviruses bearing spikes with other mutations found in circulating SARS-CoV-2 strains. This indicates that the key N501Y mutation found in the emerging U.K and South Africa variants does not create resistance to the Pfizer-BioNTech vaccine-induced immune responses.

Pfizer's website now displays various clinical trial participant metrics.


  • Pfizer and BioNTech finalized the Phase 2/3 study protocol in response to global regulators' feedback, including the FDA and the German Paul-Ehrlich-Institut. The Phase 2/3 study is an event-driven trial planned to enroll 30,000 participants between 18 and 85.

  • The Phase 2/3 trial is designed as a 1:1 vaccine candidate to placebo, randomized, observer-blinded study to obtain safety, immune response, and efficacy data needed for regulatory review. The trial’s primary endpoints will be preventing COVID-19 in those who have not been infected by SARS-CoV-2 before immunization and prevention of COVID-19 regardless of whether SARS-CoV-2 has previously infected participants.

  • Secondary endpoints include the prevention of severe COVID-19 in those groups. The study also will explore the prevention of infection by SARS-CoV-2, the virus that causes COVID-19. The primary efficacy analysis will be an event-driven analysis based on the number of participants with symptomatic COVID-19 disease. The trial design allows for interim analyses and unblinded reviews by an independent external Data Monitoring Committee.

  • The NEJM published a study on December 31, 2020.
