Be it from tap water on a vacation, some dodgy chicken, or something the kids have brought home from school, we've almost all been flattened by an awful stomach bug at some point in our lives. For moderately healthy people, symptoms clear up after a day or two, but during that time it's absolute…
Among their many important roles in maintaining human health on a microbiological level, macrophages, which are white blood cells critical to the immune system, seek out pathogens and then engulf and digest them. (It's worth noting the mice were not infected with any Salmonella strains; the process was to test whether these macrophages could trigger an effective antibody response that would essentially 'prime' the immune system to be better prepared to fight a potential pathogenic invasion.) However, this year's norovirus outbreak in the US has a different genotype to the main offenders – but the company's researchers are hopeful, given that while the vaccine candidate doesn't target this specific virus, mRNA technology allows scientists to quickly and quite easily tweak the 'recipe' to account for those genetic changes.
