Some examples of methods for vaccines delivery via phages. (a) Host could be inoculated for phage-delivered protein vaccine. (b) As in (a) host is inoculated for phage-delivered protein vaccine but the protective antigen is expressed as prokaryotic coat protein fusion. (c) Inoculation of host for phage mediated DNA vaccination. (d) Host can be inoculated for hybrid phage vaccination, where in one construct protein and DNA vaccines are delivered through phage. (e) Host inoculation for standard DNA vaccination.
