Authorization granted for particularly vulnerable individuals 12 years of age and older

Swissmedic also authorized a third dose for individuals 12 years of age and older with a weakened immune system

Moderna, Inc. (Nasdaq:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today announced Swissmedic has authorized a booster dose of Spikevax, the Company’s vaccine against COVID-19, at the 50 µg dose level in particularly vulnerable individuals 12 years of age and older, at least six months after completion of the primary series.

Swissmedic also approved a third dose of Spikevax at the 100 µg dose level for people with a weakened immune system at least 28 days after the second dose.

“We thank Swissmedic for their review and decision. This approval is supported by clinical evidence that a 50 µg booster dose induces a strong immune response against COVID-19. We also appreciate their approval of a third dose of Spikevax for those with weakened immune systems,” said Stéphane Bancel, Chief Executive Officer of Moderna. “We believe that mRNA vaccines are well positioned to adapt to the evolving epidemiology of SARS-CoV-2. We are grateful for the opportunity to provide individuals in Switzerland with another layer of protection.”

About Moderna

In 10 years since its inception, Moderna has transformed from a science research-stage company advancing programs in the field of messenger RNA (mRNA), to an enterprise with a diverse clinical portfolio of vaccines and therapeutics across six modalities, a broad intellectual property portfolio in areas including mRNA and lipid nanoparticle formulation, and an integrated manufacturing plant that allows for both clinical and commercial production at scale and at unprecedented speed. Moderna maintains alliances with a broad range of domestic and overseas government and commercial collaborators, which has allowed for the pursuit of both groundbreaking science and rapid scaling of manufacturing. Most recently, Moderna’s capabilities have come together to allow the authorized use of one of the earliest and most effective vaccines against the COVID-19 pandemic.

Moderna’s mRNA platform builds on continuous advances in basic and applied mRNA science, delivery technology and manufacturing, and has allowed the development of therapeutics and vaccines for infectious diseases, immuno-oncology, rare diseases, cardiovascular diseases and auto-immune diseases. Moderna has been named a top biopharmaceutical employer by Science for the past six years. To learn more, visit www.modernatx.com.

IMPORTANT SAFETY INFORMATION

• Do not administer Spikevax to individuals with a known history of severe allergic reaction (e.g., anaphylaxis) to any component of Spikevax.
  
  
  
  
• Appropriate medical treatment to manage immediate allergic reactions must be immediately available in the event an acute anaphylactic reaction occurs following administration of Spikevax. Monitor Spikevax recipients for the occurrence of immediate adverse reactions according to the Centers for Disease Control and Prevention guidelines (https://www.cdc.gov/vaccines/covid-19/clinical-considerations/managing-anaphylaxis.html).
  
  
  
  
• Postmarketing data demonstrate increased risks of myocarditis and pericarditis, particularly within 7 days following the second dose.
  
  
  
  
• Syncope (fainting) may occur in association with administration of injectable vaccines. Procedures should be in place to avoid injury from fainting.
  
  
  
  
• Immunocompromised persons, including individuals receiving immunosuppressive therapy, may have a diminished response to Spikevax.
  
  
  
  
• Spikevax may not protect all vaccine recipients.
  
  
  
  
• Adverse reactions reported in clinical trials following administration of Spikevax include pain at the injection site, fatigue, headache, myalgia, arthralgia, chills, nausea/vomiting, axillary swelling/tenderness, fever, swelling at the injection site, and erythema at the injection site, and rash.
  
  
  
  
• Anaphylaxis and other severe allergic reactions, myocarditis, pericarditis, and syncope have been reported following administration of Spikevax during mass vaccination outside of clinical trials.
  
  
  
  
• Available data on Spikevax administered to pregnant women are insufficient to inform vaccine-associated risks in pregnancy. Data are not available to assess the effects of Spikevax on the breastfed infant or on milk production/excretion.
  
  
  
  
• Additional adverse reactions, some of which may be serious, may become apparent with more widespread use of Spikevax.
  
  
  
  
• The black equilateral triangle denotes that additional monitoring is required to capture any adverse reactions. This will allow quick identification of new safety information. Individuals can help by reporting any side effects they may get. Side effects can be reported to EudraVigilance (https://www.adrreports.eu/) or directly to Moderna using email EMEAMedinfo@modernatx.com.
