My daughter received her second dose of hepatitis A vaccination yesterday. She is 18 yrs old. She was experiencing some cold symptoms, but mild after having a cold for two weeks. Today we took her in to the clinic to be tested for Mono as she had been exposed some weeks back by another student and has been struggling with symptoms of a cold, we took her in this morning because her she woke with a sore throat. At the appointment she tested negative to mono. The NP had indicated her heart rate was faster. I am now reading of the side effects of the vaccine. She doesn't notice a faster heartbeat, but the NP did. Should I be concerned.
