Novavax Hosts HM King Carl XVI Gustaf and HM Queen Silvia of Sweden During Royal Visit to Uppsala County

GAITHERSBURG, Md., Sept. 24, 2021 /PRNewswire/ -- Novavax, Inc. (Nasdaq: NVAX), a biotechnology company dedicated to developing and commercializing next-generation vaccines for serious infectious diseases, hosted HM King Carl XVI Gustaf and HM Queen Silvia for a visit to Novavax AB, the company's Uppsala, Sweden manufacturing affiliate on Thursday, September 23. The visit included a discussion of NVX-CoV2373, Novavax' recombinant nanoparticle protein-based COVID-19 vaccine candidate, and the company's role in combatting the global pandemic.

"We applaud the royal family for their exceptional leadership in supporting vaccination efforts to end the pandemic both in Sweden and globally," said Magnus Sävenhed, Managing Director, Novavax AB. "Novavax AB was delighted to share an overview of our progress and operations as we continue to grow our presence in Uppsala and build a global vaccine arsenal in the fight against COVID-19."

One of two Novavax-owned manufacturing affiliates, Novavax AB produces the Company's patented saponin-based Matrix-M™ adjuvant, a key component in several vaccine candidates that has been shown to improve immune responses and enable vaccine dose-sparing. It is currently being evaluated in vaccine candidates, including NVX-CoV2373, NanoFlu™, a recently announced investigational COVID-NanoFlu Combination Vaccine, and in clinical studies of several malaria vaccines.

About NVX-CoV2373
NVX-CoV2373 is being evaluated in two pivotal Phase 3 trials: a trial in the U.K. that demonstrated efficacy of 96.4% against the original virus strain, 86.3% against the Alpha (B.1.1.7) variant and 89.7% efficacy overall; and the PREVENT-19 trial in the U.S. and Mexico that demonstrated 100% protection against moderate and severe disease and 90.4% efficacy overall. It was generally well-tolerated and elicited a robust antibody response.

NVX-CoV2373 is a protein-based vaccine candidate engineered from the genetic sequence of the first strain of SARS-CoV-2, the virus that causes COVID-19 disease. NVX-CoV2373 was created using Novavax' recombinant nanoparticle technology to generate antigen derived from the coronavirus spike (S) protein and is formulated with Novavax' patented saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies. NVX-CoV2373 contains purified protein antigen and can neither replicate, nor can it cause COVID-19.

Novavax' COVID-19 vaccine is packaged as a ready-to-use liquid formulation in a vial containing ten doses. The vaccination regimen calls for two 0.5 ml doses (5 microgram antigen and 50 microgram Matrix-M adjuvant) given intramuscularly 21 days apart. The vaccine is stored at 2°- 8° Celsius, enabling the use of existing vaccine supply and cold chain channels.

About NanoFlu™
NanoFlu™ is a quadrivalent recombinant hemagglutinin (HA) protein nanoparticle influenza vaccine produced in Novavax' SF9 insect cell baculovirus system. NanoFlu uses HA amino acid protein sequences that are the same as the recommended wild-type circulating virus HA sequences and contains Novavax' patented saponin-based Matrix-M adjuvant.

About Matrix-M™ Adjuvant
Novavax' patented saponin-based 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.

About Novavax
Novavax, Inc. (Nasdaq: NVAX) is a biotechnology company that promotes improved health globally through the discovery, development and commercialization of innovative vaccines to prevent serious infectious diseases. The company's proprietary recombinant technology platform combines the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticles designed to address urgent global health needs. Novavax is conducting late-stage clinical trials for NVX-CoV2373, its vaccine candidate against SARS-CoV-2, the virus that causes COVID-19. NanoFlu™, its quadrivalent influenza nanoparticle vaccine, met all primary objectives in its pivotal Phase 3 clinical trial in older adults and will be advanced for regulatory submission. Both vaccine candidates incorporate Novavax' proprietary saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies.
