Insights

Seasonal human coronaviruses (HCoVs) cause common colds but can lead to severe illness. This review explores HCoV vaccines, finding cross-reactivity with SARS-CoV-2 offers potential for broad-spectrum protection against coronaviruses.

Area of Science:

  • Virology
  • Immunology
  • Vaccinology

Background:

  • Seasonal human coronaviruses (HCoVs) are significant causes of respiratory illness, particularly in vulnerable groups.
  • Despite typically mild symptoms, HCoVs possess antigenic drift potential and can cause severe disease.

Purpose of the Study:

  • To systematically review the pathogenesis, epidemiology, and antigenic determinants of seasonal HCoVs.
  • To summarize advances in seasonal HCoV vaccine development across diverse platforms.
  • To explore cross-reactivity between SARS-CoV-2 and seasonal HCoV vaccines for broad-spectrum protection.

Main Methods:

  • Systematic review of literature on seasonal HCoV pathogenesis, epidemiology, and vaccine development.
  • Analysis of preclinical and clinical data on vaccine cross-reactivity.
  • Examination of viral genomic architecture and antigenic determinants.

Main Results:

  • Seasonal HCoVs exhibit antigenic drift and potential for severe disease, necessitating vaccine development.
  • Various vaccine platforms (inactivated, mRNA, VLP, etc.) are being explored for seasonal HCoV protection.
  • Cross-reactivity between SARS-CoV-2 and seasonal HCoV vaccines targets conserved epitopes, supporting broad-spectrum strategies.

Conclusions:

  • Developing broad-spectrum vaccines targeting conserved epitopes is crucial for protection against seasonal HCoVs and future zoonotic threats.
  • Further research into pathogenesis and innovative vaccine strategies integrating humoral and cellular immunity is needed.
  • Pan-coronavirus vaccines hold promise for protecting vulnerable populations and mitigating pandemic risks.
