There are presently four major types of COVID-19 vaccines in developmental stages, some of which have already been approved in various countries. They include:

  • Viral vector vaccines
  • Gene-based vaccines (mRNA) (nucleic acid)
  • Inactivated vaccines with viral proteins (protein subunit)
  • Live-attenuated vaccines (‘whole virus’)
