Yes good question to ask your doctor. Here is what the CDC says about Ivig/intravenous immunoglobulin and the covid vaccines-
www.cdc.gov/vaccines/covid-19/info-by-product/clinical-considerations.html
For persons receiving antibody therapies not specific to COVID-19 treatment (e.g., intravenous immunoglobulin, RhoGAM), administration of mRNA COVID-19 vaccines either simultaneously with or at any interval before or after receipt of an antibody-containing product is unlikely to substantially impair development of a protective antibody response. Thus, there is no recommended minimum interval between other antibody therapies (i.e., those that are not specific to COVID-19 treatment) and mRNA COVID-19 vaccination.
