Live recombinant viral vectors based on adenoviruses and poxviruses are among the most promising platforms for development of new vaccines against diseases such as malaria, tuberculosis, and HIV-AIDS. Vaccines based on live viruses must remain infectious to be effective, so therefore need continuous refrigeration to maintain stability and viability, a requirement that can be costly and difficult, especially in developing countries. The sugars sucrose and trehalose are commonly used as stabilizing agents and cryoprotectants for biological products. Here, we have exploited the ability of these sugars to vitrify on desiccation to develop a thermostabilization technique for live viral vaccine vectors. By slowly drying vaccines suspended in solutions of these disaccharide stabilizers onto a filter-like support membrane at ambient temperature, an ultrathin glass is deposited on the fibers of the inert matrix. Immobilization of two recombinant vaccine vectors-E1/E3-deleted human adenovirus type 5 and modified vaccinia virus Ankara-in this glass on the membranes enabled complete recovery of viral titer and immunogenicity after storage at up to 45 degrees C for 6 months and even longer with minimal losses. Furthermore, the membrane carrying the stabilized vaccine can be incorporated into a holder attached to a syringe for almost simultaneous reconstitution and injection at point of use. The technology may potentially be developed for the deployment of viral vector-based biopharmaceuticals in resource-poor settings.
This research output has an Altmetric Attention Score of 22. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 July 2026.
All research outputs
#1,984,302
of 30,691,887 outputs
Outputs from Science Translational Medicine
#3,010
of 5,625 outputs
Outputs of similar age
#6,752
of 123,745 outputs
Outputs of similar age from Science Translational Medicine
#6
of 34 outputs
Altmetric has tracked 30,691,887 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 93rd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 5,625 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 93.4. This one is in the 46th percentile – i.e., 46% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 123,745 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 94% of its contemporaries.
We're also able to compare this research output to 34 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 82% of its contemporaries.
