ALB and infection: For example, Shaw et al. used a cotton rat model of VAERD following vaccination with the FI-RSV vaccine (Shaw et al., 2013b) to show that the presence of non-viral cell-culture-derived contaminants such as bovine serum albumin drives a bulk of the inflammation following challenge with RSV, while it is not the case following natural infection of children (Shaw et al., 2013b).
