mRNA influenza vaccine

  • Clinical Trial of mRNA Universal Influenza Vaccine Candidate Begins
  • https://www.niaid.nih.gov/news-events/clinical-trial-mrna-universal-influenza-vaccine-candidate-begins
  • https://clinicaltrials.gov/ct2/show/NCT05755620
  • Clinical trial, experimental universal influenza vaccine
  • National Institute of Allergy and Infectious Diseases’ (NIAID) Vaccine Research Center (VRC),
  • (part of National Institutes of Health)
  • Enrolling volunteers, Duke University, Durham, North Carolina
  • Phase 1 trial
  • H1ssF-3928 mRNA-LNP, for safety and ability to induce an immune response.
  • N = up to 50 healthy volunteers, (18 through 49)
  • Three groups of 10 participants each
  • 10, 25 and 50 micrograms
  • After evaluation of the data to determine an optimum dosage,
  • an additional 10 to receive the optimum dosage
  • Study include a group, receive a current quadrivalent.
  • Comparison between “immunogenicity and safety”
  • Follow-up appointments for up to one year
  • Annual seasonal flu vaccines
  • Valuable tools in controlling the spread and severity of influenza
  • Do not provide immunity against every flu strain.
  • Each year is based on prediction
  • Vaccine manufacturers then need time
  • (dominant strains of the virus can change)
  • An effective universal flu vaccine
  • Acting NIAID Director Hugh Auchincloss
  • Protecting its recipients against a wide variety of strains,
  • ideally providing durable long-term immunity.
  • “A universal influenza vaccine would be a major public health achievement and could eliminate the need for both annual development of seasonal influenza vaccines, as well as the need for patients to get a flu shot each year”
  • Defence against the spread of a future flu pandemic.
  • Both vaccines use a specific portion of a flu protein,
  • Hemagglutinin (HA) stern (not head) flu protein
  • UK cements 10-year-partnership with Moderna in major boost for vaccines and research

  • £1bn deal with the UK government
  • UK government has committed to buying Moderna’s vaccines for the next decade.

  • Innovation and Technology Centre built by the 2025
  • Moderna
  • provide the UK public with access to mRNA vaccines for a wide range of respiratory diseases
  • Questions
  • Control of antigen dose?
  • How long antigen will be produced for?
  • Degree of systemic distribution?
  • Degree of systemic inflammation?
