Questions and Answers

What is the primary method used to propagate influenza virus for the production of split virion vaccines?

  • Propagation in chicken eggs (correct)
  • Cell-based propagation
  • Propagation in plants
  • Propagation in mammalian cells

    • What is the main purpose of disrupting virus particles with detergents in the creation of split virion vaccines?

  • To release haemagglutinin and neuraminidase glycoproteins (correct)
  • To destroy the virus particles
  • To decrease the side effects of the vaccine
  • To increase the potency of the vaccine

    • Why were routine influenza vaccines extended to children in the mid-2010s?

  • Children were at a higher risk of severe infection
