Question
Are babies aged 2, 3, and 4 months old eligible for the pentavalent vaccine?
Answer
The vaccination schedule for the pentavalent vaccine is as follows: administered at 2, 3, and 4 months, or at 1.5 years old. Newborns can start receiving the second dose of the DTP vaccine at 3 months after birth, with a total of 3 doses, with at least a 28-day interval between each dose. At the age of 1.5 to 2 years, a booster dose of the DTP vaccine is required to strengthen immunity. At the age of 7, a refined diphtheria vaccine or a refined diphtheria-tetanus vaccine is required to further strengthen immunity.
