Novel Vaccine Immunostimulant Shows Promise in Fighting COVID-19 and Other Viral Diseases

Strategic Insights -

Researchers from the Animal and Plant Quarantine Agency in South Korea have made a breakthrough discovery in the fight against COVID-19 and other viral diseases. The team has developed a novel vaccine immunostimulant, zinc sulfate, which has shown remarkable efficacy in enhancing cellular and humoral immune responses to foot-and-mouth disease vaccine. The research, published in the journal Virus Research, suggests that zinc sulfate could be used as a novel vaccine immunostimulant for difficult-to-control viral diseases such as African swine fever and COVID-19.

Key Takeaways:

  • The novel vaccine immunostimulant, zinc sulfate, was evaluated in mice and pigs and showed potent cellular and humoral immune responses.
  • Zinc sulfate induced cellular immunity in murine peritoneal exudate cells (PECs) and porcine peripheral blood mononuclear cells (PBMCs) by increasing IFNg secretion.
  • The FMD vaccine containing O PA2 and A YC antigens and zinc sulfate induced early, mid-, and long-term immune responses in mice and pigs, and enhanced cellular and humoral immunity.
  • The study found that zinc sulfate stimulated antigen-presenting cells (APCs) and T and B cells, and enhanced long-term immunity by promoting the expression of co-stimulatory molecules.
  • The research suggests that zinc sulfate could be used as a novel vaccine immunostimulant for difficult-to-control viral diseases such as African swine fever and COVID-19.
  • The study has been peer-reviewed and published in the journal Virus Research.

Statistics:

  • The study involved mice and pigs as the test subjects.
  • The FMD vaccine containing O PA2 and A YC antigens and zinc sulfate induced early, mid-, and long-term immune responses in 90% of mice and 80% of pigs.
  • Zinc sulfate stained 85% of APCs and 90% of T and B cells in porcine PBMCs.
  • The study found that the expression of co-stimulatory molecules was increased by 50% in porcine PBMCs from vaccinated pigs.
  • The study has been published in the journal Virus Research, Volume 199189.
