Novavax COVID-19 Vaccine Description 2022

Novavax COVID-19 vaccine (Nuvaxovid™, CovoVax™, NVX-CoV2373)  is a protein-based vaccine engineered from the genetic sequence of the first strain of the SARS-CoV-2 beta coronavirus. The COVID-19 (SARS-CoV-2 rS [Recombinant, adjuvanted)) vaccine was created using Novavax's proprietary nanoparticle technology, Matrix-M™, an adjuvant to enhance immune responses and stimulate high levels of neutralizing antibodies. Matrix-M adjuvant has demonstrated a potent and well-tolerated effect by stimulating the entry of antigen-presenting cells into the injection site and enhancing antigen presentation in local lymph nodes, boosting immune response and helping an immunized person make antibodies against the coronavirus. 

Novavax Inc.'s vaccines are genetically engineered using three-dimensional nanostructures of recombinant proteins critical to disease pathogenesis. The COVID-19 vaccine creates an engineered baculovirus containing a modified coronavirus spike protein gene. The baculovirus then infects a culture of Sf9 moth cells, which generate the spike protein and display it on their cell membranes. Next, the spike proteins are harvested and assembled onto a synthetic lipid nanoparticle about 50 nanometers across, each displaying up to 14 spike proteins.

The U.S. FDA issued on Jul. 13, 2022, an emergency use authorization (EUA) for the Novavax COVID-19 Vaccine, Adjuvanted for the prevention of COVID-19 caused by the SARS-CoV-2 coronavirus in individuals 18 years of age and older. On Dec. 17, 2021, the World Health Organization (WHO) granted Emergency Use Listing for Novavax's NVX‑CoV2373 vaccine manufactured and marketed by Serum Institute of India Pvt. Ltd. (SII) named CovoVax. Novavax's COVID-19 vaccine (Nuvaxovid) was authorized by the European Medicines Agency (EMA) and European Commission (EC) for adults on Dec. 20, 2021 - E.U. study number: EudraCT number, 2020-004123-16. As of Jun. 13, 2022, the WHO's Strategic Advisory Group of Experts on Immunization (SAGE) had issued updated interim policy recommendations. On Jun. 16, 2022, the EMA published clinical data EMEA/H/C/005808/0000. The EMA's human medicines committee (CHMP) recommended granting an extension of indication for the COVID-19 vaccine Nuvaxovid developed by Novavax CZ, a.s., to include adolescents aged 12 to 17 years. On July 5, 2022, the EC approved the expanded conditional marketing authorization.

On Jul. 17, 2022, a non-peer-reviewed study found showed that after two Novavax vaccine doses, Omicron sub-lineages BA.1 and BA.4 were resistant to neutralization by 72% (21/29) and 59% (17/29) of samples. However, after the third dose of NVX-CoV2373, observed high titers against Omicron BA.1 (GMT: 1,197) and BA.4 (GMT: 582), similar in magnitude to those triggered by three doses of an mRNA vaccine.

Novavax and U.S. FDA Authorization

As of Aug. 8, 2022, Novavax received U.S. FDA EUA and CDC recommendations for NVX-CoV2373, marking the first protein-based COVID-19 vaccine authorized in the U.S. for adults. About 332,000 doses of Novavax's COVID-19 vaccine have been distributed in the USA as of August 4, 2022, and more than 2,300 people have been fully vaccinated, according to data from the U.S. CDC. Previously, the U.S. CDC Director Rochelle P. Walensky, M.D., M.P.H., endorsed the CDC Advisory Committee on Immunization Practices (ACIP) recommendation on Jul. 19, 2022, that Novavax’s COVID-19 vaccine be used as another primary series option for adults (18+ yrs). The ACIP conducted a digital review meeting led by Dr. Grace Lee, the presentations are posted on this CDC weblink. Filip Dubovsky, MD, MPH, with Novavax, Inc., presented this vaccine information.

The FDA issued an EUA on Jul. 13, 2022, for the Novavax COVID-19 Vaccine. On July 11, 2022, Novavax announced an agreement with the U.S. HHS, in collaboration with the Department of Defense, to secure an initial 3.2 million doses of Novavax's COVID-19 vaccine should it receive a U.S. FDA EUA and a recommendation from the CDC. Novavax's vaccine would become available for free to states, jurisdictions, federal pharmacy partners, and federally qualified health centers. The emergency use of this product is only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of the medical product under Section 564(b)(1) of the FD&C Act unless the declaration is terminated or authorization revoked sooner. 

Novavax announced on Jul 1, 2022, that clinical data generated to date demonstrate that this prototype vaccine offers broad immune responses, including against circulating variants, such as the Omicron BA.4/5. 

Novavax, Inc. participated in the U.S. FDA Vaccines and Related Biological Products Advisory Committee's meeting, which resulted in a 19-2 vote to recommend the inclusion of a SARS-CoV-2 Omicron component for COVID-19 booster vaccines in the U.S. beginning in the Fall of 2022. During the meeting, Novavax highlighted data showing that the structural features of Novavax's protein-based COVID-19 vaccine, enhanced by the Matrix-M™ adjuvant, displayed epitopes across both the original strain and emerging variants contributing to the generation of broadly cross-reacting antibodies. Additional data from Phase 2 and Phase 3 trials, as well as in vitro data on neutralizing antibodies and receptor inhibition from trial participants, show cross-reactivity with all variants tested, particularly following booster doses.

On Jun. 7, 2022, the FDA's Vaccine Committee's twenty-two members voted 21 yes, with one abstaining, to endorse the protein-based Novavax COVID19 vaccine authorization. The FDA staff makes all final authorization or approval decisions. Novavax issued a statement on Jun. 3, 2022, 'the data from our placebo-controlled studies show that overall, in our clinical development program, the rate of myocarditis was balanced between the vaccine and placebo arms (0.007% and 0.005%). Furthermore, in the post-crossover portions of our studies, the cases we have seen are all within the expected rate. And, 'Based on our interpretation of all the clinical data supporting NVX-CoV2373, including over 50,000 participants in clinical trials, we believe there is insufficient evidence to establish a causal relationship. We will continue to monitor all adverse events, including myocarditis and pericarditis.'

On Jun. 7, 2022, the FDA VRBPAC digital meeting will review various authorization presentations. "Based on the efficacy estimate in the clinical trial of this vaccine, it is more likely than not that the vaccine will provide some meaningful level of protection against COVID-19 due to Omicron, in particular against more severe disease."

Novavax Omicron BA.x

As of Aug. 4, 2022, the U.S. NIH's OpenData Portal reported in vitro Therapeutic Activity against the Omicron variant and sublineages. But, the breaking nature of these releases should be interpreted with caution. During the U.S. FDA Vaccines and Related Biological Products Advisory Committee Meeting on Jun. 28, 2022, Novavax's Gregory M. Glenn, M.D. President, R&D, presented 'Structural features of our recombinant trimeric spike protein vaccine leads to broadly cross-neutralizing antibodies. Novavax technology induces cross-reactive immunity driven by recognition of conserved epitopes on Novavax recombinant spike protein, and the adjuvant enhances the breadth and duration of an immune response.

And Novavax announced on Feb. 10, 2022, data from the pediatric expansion of phase 3 PREVENT-19 study showed in post hoc analyses robust immune responses in adolescents, including IgG responses against Spike proteins of several variants (including Alpha, Beta, Delta, Gamma, Mu, and Omicron) that were 2-3-fold higher than in adults, with 100% seroconversion against all variants following a 2-dose series of vaccinations. Adolescent functional immune responses (hACE2 receptor inhibition) against these variants were 2.4-4-fold higher than in adults against all evaluated variants.

Novavax Availability

As of Aug. 13, 2022, Novavax's vaccine has received various authorizations from more than 43 countries and is Listed by the World Health Organization (WHO). Over 73 million doses delivered globally to date.

In 2021, Novavax licensed and transferred its manufacturing technologies and is supplying the Matrix-M™ adjuvant to enable Takeda to manufacture the vaccine at its Hikari facility in Japan.

On Jul. 7, 2020, Novavax was awarded $1.6 billion by the U.S. federal government to complete late-stage clinical development, including a pivotal Phase 3 clinical trial; establish large-scale manufacturing, and deliver 100 million doses of NVX‑CoV2373. And the Coalition for Epidemic Preparedness Innovations has provided critical support to Novavax, including the commitment of approximately $400 million to advance early clinical development and manufacturing scale-up around the globe.

Novavax Indication

Novacax's Nuvaxovid NVX-CoV2373 vaccine has demonstrated efficient binding with receptors targeted by the SARS-CoV-2 virus, a critical aspect for effective vaccine protection. The journal Nature published an article on November 8, 2021: How protein-based COVID vaccines could change the pandemic.

Novavax Pediatrics

The company says the use of the vaccine in adolescents is the same as in adults, with two injections given in a muscle three weeks apart. On July 26, 2022, Japan and Australia authorized adolescents aged 12 through 17 to receive Nuvaxovid.

Novavax announced on August 4, 2022, the Phase 2b/3 Hummingbird™ global clinical trial. The trial will evaluate the safety, effectiveness (immunogenicity), and efficacy of two doses of the Novavax COVID-19 vaccine in younger children aged six months through 11 years, followed by a booster at six months after the primary vaccination series, with Initial results expected in Q1 2023. And on May 4, 2022, the submission of variations to the Australian Therapeutic Goods Agency, New Zealand's Medsafe, and Great Britain to expand the provisional approval of its Nuvaxovid for active immunization to prevent COVID-19 caused by SARS-CoV-2 in adolescents aged 12 through 17 years. The Drugs Controller General of India approved NVX-CoV2373 for restricted use in an emergency for adolescents aged 12 through 17 years in India. S.K. bioscience also recently submitted a regulatory filing for adolescent vaccine authorization to the South Korean Ministry of Food and Drug Safety. And in Thailand and Japan on April 18, 2022.

On February 10, 2022, the PREVENT-19 pediatric study expansion in adolescents aged 12 through 17 achieved a primary effectiveness endpoint demonstrating comparability to the adult population; Trial demonstrated 82% clinical efficacy against Delta variant; Immune responses were about two-to-three-fold higher in adolescents than in adults against all variants studied; the Vaccine was well-tolerated with no safety signals identified.

Novavax Boosters

In the USA, use the CDC’s COVID-19 booster tool to learn if and when you can get boosters to stay up to date with your COVID-19 vaccines. Boosters are not recommended at this time for anyone who has completed the Novavax COVID-19 two-dose primary series.

And in Australia, the Therapeutic Goods Administration granted provisional approval on July 6, 2022, to Biocelect Pty Ltd (on behalf of Novavax Inc) for its COVID-19 vaccine NUVAXOVID for use as a booster in individuals aged 18 years and older. Nuvaxovid became the first protein-based COVID-19 vaccine registered for use as a booster regardless of previous vaccine history on June 13, 2022. The third (booster) dose may be administered approximately 6 months following completion of a primary series in individuals aged 18 years and older. This includes use as a booster in a homologous series (following a primary series of NUVAXOVID); or in a heterologous series for individuals who received either an mRNA (COMIRNATY or SPIKEVAX) or a viral vector vaccine (VAXZEVRIA) for their primary vaccination course, after consultation with a medical professional. Japan also issued booster authorization for Nuvaxovid Intramuscular Injection.

The WHO Strategic Advisory Group of Experts on Immunization recommended on December 21, 2021, the primary two-dose vaccination series of NVX-CoV2373 in persons aged 18 and older, and an additional third dose of NVX-CoV2373 administered to immunocompromised persons. On December 22, 2021, Novavax confirmed a third dose produced increased immune responses comparable to or exceeding levels associated with protection in Phase 3 clinical trials, with a 9.3-fold IgG rise and a 19.9-fold ACE2 inhibition increase after a booster dose.

Novavax Side Effects

Filip Dubovsky, M.D., MPH, with Novavax, Inc., presented heart health (Post-Authorization Myocarditis / Pericarditis) information - 1,072,074 doses administered worldwide as of June 30, 2022; Broad search safety database yielded 68 potential reports; Reports often had limited information; Brighton Collaborative Case definition used to evaluate reports: 1 met the definitive case definition of myocarditis, 6 met the probable case definition of myocarditis, 10 met the probable case definition of pericarditis.

The EMA updated the label for Novavax's COVID-19 vaccine (NVX-CoV2373) to include the risk of severe allergic reactions on Jul. 14, 2022. This EMA update is a warning commonly included for commercially available vaccines, including COVID-19 vaccines. However, Novavax’s clinical development program reported no severe allergic reactions, and therefore, this risk was not listed in the initial product label. With the broader deployment of doses, Novavax received (2) reports of anaphylaxis (allergic reaction) that met a probable/definite case definition. Because anaphylaxis can occur with all vaccines and based on these cases, Novavax and the EMA agreed to update the label accordingly: A second dose of the vaccine should not be given to those who have experienced anaphylaxis to the first dose of Nuvaxovid.

The EMA reported Nuvaxovid had a total of 964 cases of suspected side effects spontaneously reported from EU/EEA countries; none of these reported a fatal as of May 15, 2022.

The WHO says Nuvaxovid is contraindicated in persons who have a hypersensitivity to the active substance or to any of the excipients. Appropriate medical treatment and supervision should be available in an anaphylactic reaction.
