The following vaccines are generally required for children aged two weeks: 1. The vaccine for brain B is needed because brain B often causes fever, convulsions and coma in children, which is more harmful to children, and the vaccine for brain B needs to be boosted at this time. 2. The vaccine for hepatitis A can effectively prevent hepatitis A from occurring in children, thus avoiding liver function damage and jaundice. 3, Other self-funded vaccines can be administered, such as the hand, foot and mouth disease vaccine, which can be applied to children at the age of two weeks to effectively prevent the occurrence of severe hand, foot and mouth disease because children are prone to hand, foot and mouth disease.
