Advantages to inactivated vaccines (IVs)

- lowered immunogenicity
- requirement for multiple-dose regimens to establish long-lasting immunity
- may require adjuvants to immunize the aging population 
- cold chain

Inactivated vaccines in clinical trial for SARS-CoV-2

IVs are pathogens (or fractions thereof) that have been inactivated by heat or chemical reaction

Virus vaccines use the virus itself, or  in a weakened or inactive form.

nanomaterial path forward

Information gained from studies done on both the immune response and vaccine development to related betacoronaviruses can help us gain insight on the immunopathology of SARS-CoV-2 and guide the devlopment of a vaccine.

Live-attenuated vaccines (LAVs) are live, reproducing, yet mild viruses. The designs are meant to produce single-dose immunity without illness.
