Impact of waning immunity against SARS-CoV-2 severity exacerbated by vaccine hesitancy
Fig 3
Impacts of longer transmission-blocking vaccines on severity dynamics.
In (A) and (B), the vaccination rates are 0.01 per week and 0.02 per week, respectively. In both panels, the top row denotes the total fraction Itotal = IP + IS + Iw of individuals that are infected. The second to fourth rows are as in the rows of each panel of Fig 2 (see caption of Fig 2 for definitions). Across both panels, we assume that the duration of vaccinal transmission-blocking immunity is 90% of the duration of severity-blocking immunity (the columnar label), and that transmission-blocking and severity-blocking immunity after infection last 0.25 years and 1.5 years, respectively (i.e. years and
years).
