If the frequency and magnitude of response improves following intramuscular vaccination, the protective efficacy of this alternative route of administration will then need to be determined. H type 1 and other histo-blood group antigens serve as receptors or attachment factors for human noroviruses and thus influence host susceptibility. . Vaxart believes that tableted vaccines are easier to distribute and administer than injectable vaccines and have the potential to significantly increase vaccination rates. In the United States, outbreaks occur between November and April. In some cases, norovirus can be detected in stool for up to 14 days or even longer.
