Key insights

• ⚙️ mRNA vaccines trigger an immune response using the body's cellular machinery without causing infection.
• 🧬 mRNA encodes instructions for protein production, and the mRNA in vaccines introduces the body to a harmless part of a virus to train the immune response.
• 🔬 A nanoparticle, 1,000 times smaller than the average cell, is made of lipids engineered to protect mRNA on its journey through the body.
• 🧪 mRNA vaccines deliver viral genetic material to cells but cannot alter DNA.
• 💉 The COVID-19 vaccine triggers the immune response by producing antibodies to fight the virus, reducing the threat of catching new strains.
• ⏭️ mRNA vaccines don’t contain viral particles and can be easily adjusted to treat different diseases, potentially allowing for the development of new vaccines in weeks.

Q&A

• Do mRNA vaccines contain viral particles?

  mRNA vaccines do not contain viral particles and can be easily adjusted to treat different diseases, potentially allowing for the development of new vaccines in weeks.

• How do mRNA vaccines trigger the immune response?

  mRNA vaccines produce antibodies to fight the viral protein, reducing the threat of catching new strains and offering significant advantages over previous vaccines.

• Can mRNA vaccines alter DNA?

  mRNA vaccines deliver viral genetic material to cells but cannot alter DNA. Ribosomes assemble viral protein based on mRNA instructions.

• How are mRNA vaccines stored?

  mRNA vaccines are stored at -20 to -80 degrees Celsius before use to maintain their effectiveness.

• What is a nanoparticle in mRNA vaccines?

  A nanoparticle, 1,000 times smaller than the average cell, is made of lipids engineered to protect mRNA on its journey through the body. Sugars and salt are added to help maintain the nanoparticles' integrity.

• How do mRNA vaccines work?

  mRNA vaccines trigger an immune response using the body's cellular machinery without causing infection. The mRNA introduces the body to a harmless part of a virus, which helps train the immune response.

• What is the role of mRNA in vaccines?

  mRNA encodes instructions for protein production. In vaccines, it introduces the body to a harmless part of a virus to train the immune response.
