The use of the whole-cell vaccine after the initial vaccination in the first year of life might be a good idea, but we don't know yet if that would correct the immunological defects of the acellular vaccine.
Studies have suggested that protection following the acellular pertussis vaccine is less enduring than following the whole-cell pertussis vaccine," said lead study author Nicola Klein, MD, PhD, of the Kaiser Permanente Vaccine Study Center.
Participants were assigned to 1 of 4 groups based on the number of acellular pertussis vaccines (DTaP-Hib) received (0, 1, 2, or 3 doses).
Clinical effectiveness of an acellular dermal regenerative tissue matrix compared to standard wound management in healing diabetic foot ulcers: A prospective, randomized, multicentre study.
The resulting acellular matrix is a favorable microenvironment for bio-ingrowth, acting as a scaffold onto which the body can build dermal tissue through revascularization and cellular repopulation.
Standardization of different protocols was done to produce completely acellular tissue matrices by removing cellular components.
Comparing the new acellular versions with a weak whole-cell vaccine "made the acellular vaccines look good," says Plotkin, who currently advises vaccine maker Sanofi Pasteur.
a global orthopaedic manufacturer headquartered in Bruz, France, announces the launch of MemoDerm[TM] Acellular Dermal Matrix, a terminally sterilized, single-application onlay graft used to promote healing of diabetic foot ulcers and other soft-tissue repairs.
In the present study efficacy of cross-linking agents like GA, BDDGE and EDC on aortic acellular matrix graft was evaluated by in vitro biocompatibility determination.
Microscopically, there is a subepithelial, extracellular, acellular, amorphous, eosinophilic matrix deposition that is often accentuated around minor seromucus glands and vessels (figure 1).
The new, so-called acellular vaccines rely on the pertussis proteins, rather than a whole bacterium, to spark immunity and are therefore thought to be safer.
