Genetically engineered bleb vaccine
摘要:
The present invention relates to an immune-protective and non-toxic Gram-negative bleb vaccine suitable for paediatric use. Examples of the Gram-negative strains from which the blebs are made are N. meningitidis, M. catarrhalis and H. influenzae. The blebs of the invention are improved by one or more genetic changes to the chromosome of the bacterium, including up-regulation of protective antigens, down-regulation of immunodominant non-protective antigens, and detoxification of the Lipid A moiety of LPS.
