There are several studies on this from JAMA (journal oj american medical administration), Mayo Clinic and John's Hoskins. I research all of them regularly. Hope this helps

I paused my usage of RA medications for a couple weeks when getting Covid vaccines. I believe this let my immune system build a decent defense. The level of antibodies in my blood were measured good when I did this.

The Red Cross happened to be measuring antibody levels in one of my blood donations, Mar 20 2022...
"It takes 1 to 3 weeks after an infection or vaccination to reach a detectable level of antibodies.",
"Antibody Test Result: REACTIVE+", "Antibody levels were detected at levels high enough that your plasma may be used as convalescent plasma."
