 [ Symptoms ] can you contract chickenpox if you have had the vaccination  i had the vaccine for chicken pox when i was little and never contracted it however now a whole bunch of little red bumps are popping up all over my arm and the each really bad i do not own a thermometer and with it being so hot out i can not tell if i am running a fever i had a sore throat a couple of days ago but it quickly went away i am rarely hungry which is not uncommon for me and i am always tired mostly from school and work is it possible that the red bumps are chickenpox [ Disease ] the vaccine is not perfect unfortunately so yes you can still contract the disease later in life if you did not mount an protective response from that one pediatric vaccine your description of the little red bumps on your arm is just too vague for me to even guess if chicken pox is a consideration you would need to have a medical professional look at those bumps first hand
