I won't wholly disagree, but some edge cases, such as the mouse brain derived je-vax, had issues > 1 month. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8828133/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8828133/ Read the Inactivated mouse brain–derived JE vaccine section. These reactions seem to be more about mouse brain prions, and there was a rare case of (unproven!!) issues a year out, which were cited during discussions about forced discontinuation. I can't seem to find that, but anyhow, the > 1 month issues are well accepted.
