I felt sick after the first dose, should I still get the second dose?

In most cases yes, Flu-like symptoms, including fever (even high fevers), chills, fatigue, and body aches are all signs that your immune system is reacting to the vaccine and creating protective antibodies.
  • If you experienced a severe allergic reaction to the first dose you should not receive the second dose.
  • If you experienced severe side-effects, resulting in hospitalization or emergency room treatment, you should consult with your provider before to receiving the second dose.
