Hi Stewie,

My understanding is that those with reduced immunity are patients currently receiving chemotherapy or immunotherapy or have recently finished treatment. Also, patients with certain blood cancers. 

I enquired regarding this as I had a full node clearance from my groin & pelvis 10 years ago & I have been in remission since then. Lymph node removal does not cause reduced immunity, except in the area where the nodes were removed - in which case we are susceptible to localised infection ie. cellulitis, but reduced lymph nodes won't affect our immunity to the virus. I hope this helps,
