Newborns are given BCG and Hepatitis B vaccines just after birth. As long as the child’s physical condition allows, there is no premature birth, hypoxia, ischemia, low birth weight, pathological jaundice, all need to be injected on time at the birth hospital. If any of these conditions exist, they need to be replenished in a timely manner after the condition has improved. It should be noted that after BCG vaccination, most of the localized cases will be septic, and BCG spots will be left at a later stage. Do not get wet within 3 days after the vaccination to avoid local redness and infection, and you can bathe normally after 3 days.
