Will I have more side effects after the second dose of the COVID-19 vaccine?

In clinical trials, people had reactions such as fever, fatigue, headache, chills, and muscle or joint pain. These were more common after receiving the second dose than after the first. These side effects were mild or moderate in severity and only lasted about one day.*
