Daniela Staquicini (Rutgers Cancer Institute of New Jersey) and colleagues published a new paper in PNAS on the design and proof of concept of two phage-based, cold-free COVID-19 vaccination strategies. They show that aerosol vaccination with phage particles displaying short S protein epitopes, and subcutaneous vaccination with adeno-associated virus/phage particles carrying the entire S protein gene, both elicit systemic and specific immune responses in mice.
