activating your immune system is the point. 2-3 days of mild symptoms is fairly common with plenty of vaccines https://twitter.com/odotjdot/status/1351849967661449217
in fact, most of the symptoms we associate with sickness are actually the effects of your body’s immune system fighting back, not directly caused by the infection.
fever: your body trying to boil the invader out of you (assuming <98° will kill it)
chills: counteract the fever so you don’t boil your brain too
aches: increased blood volume bc of all the extra immune cells, higher pressure on your vessels

mucus/cough/sneeze: your body trying to coat and expel the infectious material from your respiratory pathways.

oh and fatigue: all the extra activity of your immune cells uses a LOT of energy, so it’s diverted. less to muscles, more to the infection
