  • Additionally, considerable efforts have been devoted to pandemic planning to ensure that safe and effective vaccines can be produced quickly in response to a pandemic emergency. (who.int)
  • However, its efficacy in adults remains inconsistent underlying the urgency for innovative research to develop more effective vaccines against this resilient pathogen. (nature.com)
  • The sequences of selected peptides were confirmed by spectral match validation and immunogenicity evaluated by IFN-gamma ELISpot against peripheral blood mononuclear cell from volunteers vaccinated with BCG, M.tb latently infected subjects or patients with tuberculosis disease. (jenner.ac.uk)
