“…There are also some observational studies on the link between virus infections and SLE (Hanlon, Avenell, Aucott, & Vickers, 2014;Rasmussen, Nielsen, Houen, & Jacobsen, 2016;Zandman-Goddard et al, 2009 Guiducci, & Coffman, 2007;Fagone, Muthumani, et al, 2014;Oon, Wilson, & Wicks, 2016). Some studies find that vaccinations against virus infections can also increase risk of SLE (Agmon-Levin et al, 2014;Geier & Geier, 2017;Wang, Shao, Wang, Xu, & Zhang, 2017), which further provides some evidence for et al, 1996;Gröndal et al, 2000). Its important role is also evidenced in our study.…”
