What does it mean if you develop a rash after getting the chickenpox vaccine?
Vaccine Side Effects
Large local reactions to vaccines, although sometimes scary looking, are not dangerous, do go away, and are not a reason your pediatrician should typically tell you to skip or delay your child’s vaccines.
Most immunization side effects are mild and only last a few days.
SIRVA, or shoulder injury related to vaccine administration occurs when a vaccine is given too high into the shoulder joint.
