The chickenpox vaccine shouldn’t be very expensive, around$160, and may vary a little from region to region and place to place, but not by much. Chickenpox is generally a rashy, highly contagious disease in children caused primarily by varicella zoster virus infection. Chickenpox is a self-limiting disease and most of the time there are no complications. If there are no complications, chickenpox can generally be self-cured within 10 days, the treatment is mainly symptomatic, such as the child’s skin is itchy, you can give the child wipe glycerine lotion, but also oral antiviral drugs, such as acyclovir, the dosage is 20mg per kilogram per time, four times a day, orally. Chickenpox infection can be acquired after a relatively long-lasting immunity, so the live attenuated varicella vaccine can be more effective in preventing the occurrence of chickenpox in children, of which the protection rate can reach 85% or 95%, and can last for more than 10 years. Therefore, if your child is relatively young, try to vaccinate your child against chickenpox when chickenpox is prevalent and highly prevalent, which is still very useful for chickenpox prevention.
