About chickenpox Vaccinations
Last update date April 1, 2023
What is chickenpox?
Chickenpox is transmitted by direct contact with varicella and shingles virus, droplet infection or airborne infection.
The incubation period is 10 to 20 days, usually 13-17 days.
The rash is initially a pupae, which spreads to blisters, pustules, and crusts (scab).
The rash tends to appear in the trunk, but also in the hair. Sometimes a mild fever may be accompanied by mild fever.
Generally, it is a mild disease, but it is severe in patients whose immune function has decreased due to leukemia or treatment.
How to Vaccinations

initial vaccinations once between 12 months and less than 36 months
After the end of initial vaccinations, varicella vaccine is given twice in booster shot once at intervals of 3 months or more (standard is 6 to 12 months).
