 ### Waning of protection against infection
-In our model we assume that receiving the monovalent booster XBB1.5 or being infected with the XBB1.5 strain results in a protection against infection of 98%. We hereby assume the the novel monovalent XBB1.5. booster protects as well against the XBB1.5. variant as the initial mRNA vaccine protected against the wild type. We assume the same waning speed for all agents.
