SpikeVax COVID-19 Vaccine For 2022

The SpikeVax COVID-19 Vaccine is a Messenger RNA (mRNA) vaccine targeted against the SARS-CoV-2 betacoronavirus to prevent severe COVID-19. SpikeVax encodes for a prefusion stabilized form of the Spike (S) protein selected by Moderna Inc. in collaboration with U.S. NIAID Vaccine Research Center investigators. SpikeVax's active ingredient is CX-024414 (single-stranded, 5’-capped mRNA) produced using a cell-free in vitro transcription from the corresponding DNA templates, encoding the S protein of the SARS-CoV-2 virus.

Moderna designs its mRNA vaccines using the virus's sequence, but not the virus itself. mRNA is a single-stranded molecule that carries genetic code from DNA in a cell's nucleus to ribosomes, the cell's protein-making machinery. The mRNA instructs a patient's cells to produce proteins that prevent, treat, or cure disease. Moderna says mRNA plays a fundamental role in human biology, transferring the instructions stored in DNA to make the proteins required in every living cell.

On Dec. 18, 2020, the U.S. FDA issued an emergency use authorization (EUA) that enabled the COVID-19 Vaccine Moderna (SpikeVax) to be distributed in the U.S. for use in individuals 18 years of age and older. And on Aug. 12, 2021, the FDA amended SpikeVax's EUA to allow for an additional dose in specific immunocompromised individuals, specifically, solid organ transplant recipients or those diagnosed with conditions considered to have an equivalent level of immunocompromised. On Nov. 19, 2021, the FDA amended the EUA for SpikeVax, 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. And on Jan. 31, 2022, the FDA Approved Moderna's COVID-19 Vaccine (Spikevax) to prevent COVID-19 in individuals 18 years of age and older. On Mar. 29, 2022, the FDA authorized a second booster dose for certain people. And on Jun. 17, 2022, the FDA authorized a version of SpikeVax for infants and young children.

SpikeVax (elasomeran mRNA vaccine) Accession Number: DB15654; Preferred Substance Name: CX-024414; UNII: EPK39PL4R4; MedlinePlus a621002. On August 29, 2022, the EMA published SPIKEVAX Clinical Updated: EMEA/H/C/005791/II/0057.

Moderna, Inc. is advancing messenger RNA science to create a new transformative medicine class for patients. mRNA medicines are designed to direct the body's cells to produce intracellular, membrane, or secreted proteins that can have a therapeutic or preventive benefit and potentially address a broad spectrum of diseases. Headquartered in Cambridge, MA. Moderna Inc.'s 10-Q SEC filing on Jan. 4, 2021, indicates 'mRNA is considered a gene therapy product by the U.S. FDA.' (pINN elasomeran). To learn more, visit

SpikeVax Vaccine Price

During the COVID-19 pandemic, the U.S. government is offering the SpikeVax vaccine at no charge in the USA.

SpikeVax Omicron BA.x Sublineages

As of Aug. 18, 2022, the U.S. NIH's OpenData Portal reported SpikeVax in vitro Therapeutic Activity against the Omicron variant. But, given the breaking nature of these releases, Omicron data should be interpreted with caution.

Spikevax Bivalent Original/Omicron (mRNA-1273.214)

Moderna confirmed on Aug. 30, 2022, that the Therapeutic Goods Administration in Australia, the Swiss Government, and the UK's Medicines and Healthcare products Regulatory Agency (MHRA) announced conditional authorizations for the use of the Omicron-containing bivalent COVID-19 booster vaccine mRNA-1273.214. And Canada ordered 12 million doses on Aug. 22, 2022.

The new version of SpikeVax targets two strains of SARS-CoV-2, the original strain and the Omicron variant of concern BA.1. The bivalent booster mRNA-1273.211 is a single 50 µg dose vaccine. The mRNA-1273.211 includes several mutations present in the Omicron variant that were also present in the Beta variant of concern. On Jul. 11, 2022, the Company announced among participants without prior infection that bivalent mRNA-1273.214 resulted in significantly higher neutralizing titers against BA.4/5 compared to the currently authorized booster, with a geometric mean ratio of 1.69 (95% CI: 1.51-1.90)1. One month after the booster, BA.4/5 neutralizing titers were 776 (95% CI: 719, 838) for mRNA-1273.214 and 458 (95% CI: 421, 499) for the currently authorized booster. The BA.4/5 geometric mean fold rise (GMFR) from pre-booster levels was 6.3-fold (95% CI: 5.7, 6.9) for mRNA-1273.214 recipients, and 3.5-fold (95% CI: 3.2, 3.9) for mRNA-1273 recipients. Consistent results were demonstrated across subgroups, including those aged 65 and older.

On Jun. 8, 2022, Moderna announced a 50 µg booster dose of mRNA-1273.214 met all pre-specified endpoints in the 437 study participants, including superior neutralizing antibody response (geometric mean ratio) against the Omicron variant one month after administration when compared to the original mRNA-1273 vaccine.

SpikeVax Side Effects

The EMA confirmed as of Aug. 3, 2022, a total of 230,524 cases of suspected side effects were spontaneously reported from EU/EEA countries; 1,086 of these reported a fatal outcome. About 155 million doses of Spikevax, including about 3.1 million doses in children and adolescents (below 18 years of age), were administered in the EU/EEA from authorization to Jun. 26, 2022.

SpikeVax Heart Risk

Dr. Tom Shimabukuro, MPH, MBA, with the U.S. CDC COVID-19 Vaccine Coordination Unit, confirmed on Jun. 7, 2022, on slide #27, that the 'current evidence supports a causal, but rare, association between mRNA COVID-19 vaccination and myocarditis and pericarditis.' As of Mar. 2022, the CDC says, 'Myocarditis is a rare, serious adverse event that has been reported primarily after receiving the second dose of mRNA COVID-19 vaccines, with the highest risk currently observed in males ages 12–29 years. The FDA authorized, and the ACIP and CDC have recommended Pfizer-BioNTech vaccines in children ages  5–11 years and adolescents ages 12–17 years based on the determination that the benefits of COVID-19 vaccination outweigh risks in these populations. Extending the interval between the first and second mRNA vaccine dose to 8 weeks might reduce the risk.'

On Apr. 3, 2022, the EMA confirmed the PRAC had determined the risk of myocarditis and pericarditis is overall 'very rare,' meaning that up to 1 case in 10,000. Additionally, the data show that the increased risk of myocarditis after vaccination is highest in younger males. 

Hui-Lee Wong, Ph.D., MSc, presented Surveillance Updates of Myocarditis/Pericarditis and mRNA COVID-19 Vaccination in the FDA BEST System during the VRBPAC meeting on Oct. 14, 2021. On Oct. 20, 2021, the ongoing analyses from the FDA and the CDC safety surveillance systems identified increased risks of inflammatory heart conditions, myocarditis, and pericarditis, following vaccination with the Moderna COVID-19 vaccine, particularly following the second dose.

SpikeVax Dosage

Moderna's SpikeVax vaccines are offered in various dose regimens, subject to country-based authorizations. 

SpikeVax History

The first clinical batch of the Moderna vaccine candidate (CX-024414), funded by the Coalition for Epidemic Preparedness Innovations, was completed on Feb. 7, 2020, and analyzed. It was shipped to the NIH on February 24th, 42 days of sequence selection. The first participant in the NIH-led Phase 1 study of the Moderna COVID-19 Vaccine (mRNA-1273) was dosed on Mar. 16, 2020, 63 days from sequence selection to Phase 1 study dosing. On Aug. 26, 2020, Moderna presented data from the Phase I trial at the Advisory Committee on Immunization Practices.

The EMA authorized SpikeVax in Jan. 2021. On Jul. 23, 2021, the EMA granted an extension of indication for Spikevax (previously COVID-19 Vaccine Moderna) to include use in children aged 12 to 17 years and people aged 18 and above. The EMA product number: EMEA/H/C/005791. This EMA medicinal product is subject to additional monitoring. On Sept. 7, 2021, Australia published updated Information on Spikevax (Moderna) COVID-19 vaccine. And on Sept. 16, 2021, Health Canada Approved the SpikeVax vaccine. 

SpikeVax Children

Moderna has received regulatory authorizations for the use of the 100 µg Moderna COVID vaccine primary series for adolescents 12 to 17 years of age in more than 40 countries. On Jun. 14, 2022, the FDA Vaccines and Related Biological Products Advisory Committee reviewed these presentations. The U.S. CDC director issued her approval for infants and toddlers to receive 2 or 3 doses of SpikeVax.

On Jul. 22, 2022, the EMA's Committee for Medicinal Products for Human Use adopted a positive opinion recommending a variation to the authorization to include a booster dose of Spikevax at the 50 µg dose level for adolescents (12-17 years) at least three months after completion of the primary series. The EMA’s human medicines committee recommended granting an extension of indication for the COVID-19 vaccine Spikevax (50 µg compared with 100 µg) to include use in children aged 6 to 11 on Feb. 24, 2022.

The Therapeutic Goods Administration in Australia granted provisional registration on Jul. 18, 2022, for the use of Spikevax, in a two-dose series of 25 µg per dose for active immunization to prevent COVID-19 in children aged 6 months to 5 years. This approval follows similar authorizations in more than 35 countries, including Australia, Canada, the European Union, and the UK. Canada issued a similar authorization on Mar. 17, 2022.

SpikeVax Cancer Patients

On Dec. 11, 2021, an observational study found that most patients with myeloid malignancies, including acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), converted to seropositivity after two doses of the mRNA vaccine. Antibody titer levels increased dramatically following the 2nd vaccine dose, indicating the potential utility for serial vaccination (i.e., additional dosing) in poorly-responsive patients. mRNA-273 SARS-CoV-2 vaccine appears to induce a strong humoral response in this population of patients with AML and MDS. stated on Mar. 28, 2022, people diagnosed with cancer developed COVID-19 antibodies after receiving the Moderna vaccine, but at lower levels than people who hadn’t been diagnosed with cancer.

Two studies published by the journal Blood on Apr. 16, 2021, evaluated immune responses to the BNT162b2 mRNA COVID-19 vaccine in patients with chronic lymphocytic leukemia and seniors diagnosed with multiple myeloma. These studies suggest that mRNA-based COVID-19 vaccines may not work as well in people with blood cancer. And on Aug. 30, 2021, the National Comprehensive Cancer Network® published the 4th version of the NCCN: Cancer and COVID-19 Vaccination guidance.

SpikeVax Women

On Jan. 26, 2022, the BMJ reported More than 36,000 reports of menstrual changes or unexpected vaginal bleeding following covid-19 vaccination (55% Comirnaty) have so far been made to the yellow card surveillance scheme run by the UK Medicine and Healthcare Products Regulatory Agency (MHRA). But as cycles naturally vary in women and the MHRA does not collect comparison data from unvaccinated people, these data cannot be used to establish whether menstrual changes increase after COVID-19 vaccination. However, a similar signal appeared in the U.S. VAERS. The CDC publishes data on COVID-19 during Pregnancy: Severity of Maternal Illness.

The WHO Strategic Advisory Group of Experts on Immunization Interim recommendations issued on Jan. 26, 2021, include but are not limited to the vaccine that can be offered to a breastfeeding woman who is part of a group recommended for vaccination (e.g., health workers); discontinuing breastfeeding after vaccination is currently not recommended.

SpikeVax Multiple Sclerosis

A study published by the JAMA Network on August 24, 2021, found the humoral response against SARS-CoV-2 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. However, delaying anti-CD20 infusions by 3 to 6 months before vaccination could increase the probability of developing appropriate humoral responses, especially in clinically and radiologically stable patients. Therefore, future studies should investigate antibody dynamics over time, if and how DMTs influence T cell-mediated responses after vaccination, and whether these biological measures reflect vaccine efficacy in preventing severe SARS-CoV-2 infection. This study's findings are similar to previous studies of immune responses in MS patients on anti-CD20 therapy after COVID-19 vaccination and in MS patients on anti-CD20 treatment who were infected with COVID-19.

SpikeVax and Fluzone

A Phase II, open-label study to assess the safety and immunogenicity of Sanofi Pasteur Fluzone® High-Dose Quadrivalent (Influenza Vaccine), 2021–2022 Formulation, and the third dose of SpikeVax, mRNA-1273 COVID-19 vaccine, administered either concomitantly or singly in adults 65 years of age and older previously vaccinated with a 2-dose schedule of the mRNA-1273 vaccine. October 20, 2021. Results interpretation Summary: The QHD00028 study results demonstrate that QIV-HD and mRNA-1273 vaccine (100µg) can be administered safely together without evidence of immunogenicity interference, supporting existing co-administration recommendations of COVID-19 and influenza vaccines.

SpikeVax Ingredients

The Moderna COVID-19 Vaccine contains the following ingredients: messenger ribonucleic acid (mRNA), lipids (SM-102, polyethylene glycol [PEG] 2000 dimyristoyl glycerol [DMG], cholesterol, and 1,2-distearoyl-sn-glycero-3-phosphocholine [DSPC]), tromethamine, tromethamine hydrochloride, acetic acid, sodium acetate, and sucrose. This vaccine does not contain: Eggs, Preservatives, or Latex, says the CDC. In addition, although SM-102 is used in the Moderna vaccine, the vaccine does not contain chloroform

On December 22, 2020, the UAE Fatwa Council, under the chairmanship of Shaykh Abdallah bin Bayyah, issued a 'fatwa' (Islamic ruling) allowing the vaccine to be used in compliance with Islamic Sharia's objectives on the protection of the human body and other relevant Islamic rulings.

SpikeVax TAK-919

On May 31, 2022, Moderna and Takeda announced the marketing authorization in Japan for Spikevax will transfer from Takeda to Moderna in Japan as of August 2022. On February 3, 2022, Takeda announced it continues to distribute Moderna's COVID-19 vaccine in Japan. To date, 50 million doses of Moderna's COVID-19 vaccine have been imported to Japan. Takeda has started importation and distribution of an additional 93 million booster doses from the beginning of 2022 for a total distribution of 143 million doses. On May 21, 2021, the COVID-19 Vaccine Moderna Intramuscular Injection (TAK-919) was authorized in Japan. On July 20, 2021, Moderna announced that the Ministry of Health, Labour, and Welfare of Japan and Takeda Pharmaceutical Company Limited have agreed to purchase.

Pan-Respiratory Booster 

Moderna's product strategy includes developing a pan-respiratory annual booster vaccine. The Company believes it could be the first to market with a COVID + Flu + RSV booster vaccine. A pan-respiratory annual single booster vaccine to cover multiple viruses could create value for the healthcare system through compliance, convenience to the customer (one vs. three injections), and reduction in vaccine administration cost. "Best-case scenario will be the fall of' 23,' Moderna CEO Stephane Bancel told a virtual World Economic Forum roundtable session on January 17, 2022.

SpikeVax mRNA-1283

mRNA-1283 is a next-generation vaccine candidate that encodes for the portions of the SARS-CoV-2 spike protein critical for neutralization. A Phase 1 study will evaluate three dose levels, 10 µg, 30 µg, and 100 µg, of the mRNA-1283 vaccine candidate given to healthy adults as a 2-dose series, 28 days apart, and one dose level, 100 µg, of mRNA-1283 given to healthy adults in a single dose.

The Phase 1 clinical trial is led and funded by the NIH's National Institute of Allergy and Infectious Diseases. The trial will enroll approximately 210 healthy adult volunteers at four clinical research sites in the U.S. (Atlanta, Cincinnati, Nashville, and Seattle).

SpikeVax mRNA-1273.213

On April 13, 2021, new preclinical data on the Company's variant-specific booster vaccine candidates were submitted as a preprint to bioRxiv. A second multi-valent candidate (mRNA-1273.213) includes many of the mutations present in the Omicron variant that were also present in the Beta and Delta variants. The Company has completed dosing at the 100 µg (N=584) dose level and plans to explore the 50 µg dose level in approximately 584 participants. Moderna will rapidly expand testing of sera from completed and ongoing multi-valent booster studies to determine if these multi-valent candidates are able to provide superior neutralizing protection against Omicron.

Moderna mRNA-1273.529

The mRNA-1273.529 vaccine candidate is part of the Company's strategy to advance variant-specific candidates for a subset of variants of significant concern. On March 10, 2022, the first participant was dosed in the Phase 2 study of mRNA-1273.214, which combines Moderna's Omicron-specific booster candidate (mRNA-1273.529) and mRNA-1273. Moderna is also evaluating mRNA-1273.529 in a Phase 2 study in the U.S. Separately, the Company is evaluating mRNA-1273.529 in a Phase 3 study in the UK, in collaboration with the National Institute for Health Research.
