Can you clarify why people should avoid physical exertion in the 14 day window?

In addition to anecdotal reports from doctors, here are 2 short papers.

> Our case report describes two adults developing herpes zoster after vaccination with tozinameran (the Pfizer- BioNTech COVID-19 mRNA vaccine). A possible cause for this reaction is a transient lymphocytopenia that occurs after the vaccination — similar to that in COVID-19 disease

> we report, besides generation of neutralizing antibodies, consistent alterations in hemoglobin A1c, serum sodium and potassium levels, coagulation profiles, and renal functions in healthy volunteers after vaccination with an inactivated SARS-CoV-2 vaccine. Similar changes had also been reported in COVID-19 patients, suggesting that vaccination mimicked an infection
As with all adverse events which may or may not be related to vaccines, we need more funding to investigate reports, identify common factors in those who were affected, then construct studies, testing and surveillance to differentiate cause from coincidence.
