The video explores various approaches to vaccine development, including traditional methods and innovative gene therapy techniques. It discusses the use of DNA and RNA in vaccine candidates and the potential of using Adeno-associated viruses (AAVs) for gene therapy against COVID-19. The video also highlights the challenges, uncertainties, and costs associated with these methods, as well as the ongoing research and trials aimed at finding effective solutions.

What is the primary tool used in gene therapy to edit genes?

• Bacteria

• Fungi

• Algae

• Viruses

What is the main goal of a vaccine?

• To expose the immune system to antigens

• To cure diseases

• To eliminate viruses completely

• To replace damaged cells

Which nucleic acids are used in some vaccine candidates to teach cells to make viral antigens?

• DNA and RNA

• Proteins and Lipids

• Minerals and Vitamins

• Carbohydrates and Fats

What is the role of Adeno-associated viruses (AAVs) in gene therapy?

• To replace damaged tissues

• To act as antibiotics

• To deliver genetic material without causing illness

• To cause diseases

What is a potential downside of AAV-based gene therapy?

• It is ineffective against all viruses

• It permanently edits germ cells

• It is too cheap to produce

• It may have long-term side effects
