Is the covid vaccine safe for me , given - (1) i am severely allergic to compazine; (2) i am prescribed emgality & administer a monthly subcutaneous injection of 120mg/ml potential for allergic reactions? any interaction between vaccine & emgality?

Probably no interaction but no PUBLISHED information. It is safe to take coronavirus vaccine (any) despite compazine allergy but anticipate staying at administration center for 30 min after injection “just to make sure “

None reported. “There are no contraindications and no concerns for people on these medications in terms of getting the mRNA vaccines,” in reference to Aimovig (erenumab), Ajovy (fremanezumab), Emgality (galcanezumab), and Vyepti (eptinezumab).

There are NO contraindications for COVID-19 vaccines in patients with migraine who are taking CGRP medications. As an aside, if you were to contract the COVID-19 infection, one post infectious complication is distinct worsening of headaches, so, it is very prudent to get vaccinated.
