Yes, but at some threshold wouldn’t this indicate a problem?

103F+ fevers are relatively rare from typical vaccines, and from my understanding a lot of the damage from COVID is immune response related.

mRNA vaccines and our immune responses to these are uncharted territory, so I’m not sure how much we can reason by analogy from other vaccines vs. first principles.

High fevers are not uncommon in babies receiving their first vaccines.

I'm not sure it indicates a problem. A fever is, itself, just an immune system response, not a "symptom" of disease.

You are correct that there is a threshold beyond which a fever becomes unsafe, but it's above 103. But fevers of 103 in the test group do not indicate that fevers of say 105 will occur in some patients.
