There are reports that the vaccine may not work as well while using immune globulin (IVIg/SCIg) and may not fully protect you from Covid with Ig still present (IVIg has a half-life of close to 30 days). The newer mRNA vaccines are less likely to be negated by the Ig treatments, but I would wait a week or two after the 2nd shot before restarting IVIg.
