Post Entyvio sore throat

This is my third infusion in a row where I get a sore throat a few hours after my infusion that is gone the next day. I let my infusion nurse know about it today, and she wants me to call in the morning if it happens again like it has. I was reading over old threads, and I was wanting clarification on what sore throat as a side effect means. Does it mean like what I am experiencing, or does it mean in general you get them more easily in illness?

I have had antibodies since June of 2018. They switched me to every 4 weeks, as I had very little in my system after 8 weeks. I am usually extra tired after my infusion, and this time I just can't warm up.
