Q: How safe are the nanoparticles used in the vaccine?

Nanoparticles are vaccines which are created through assembly on a nano-size scale, to mimic a virus structure (virus-like particle) or be encased in a protective micro-bubble of fats (liposome). Nanoparticle vaccines should be just as safe as standard “naked” protein vaccines, but are designed to give better immune responses.
