Doctors do not uniformly recommend against self-funded vaccines. Due to the large population in China, it is impossible to provide free vaccination for all vaccines, so some vaccines need to be selected by the recipient voluntarily and at his or her own expense. There is no need to vaccinate all of the many self-funded vaccines, and each self-funded vaccine has a corresponding suitable population, so you can choose the suitable self-funded vaccine according to the specific occasion as well as your physical condition: 1. Self-funded vaccines recommended for children: Parents who have the conditions are recommended to vaccinate their children with hand, foot and mouth vaccine, chickenpox vaccine, rotavirus vaccine, pneumococcal conjugate vaccine, Haemophilus influenzae type b vaccine, etc. as much as possible Self-financed vaccines. Since children’s resistance is relatively weak, common hand, foot and mouth disease, chickenpox, diarrhea and pneumonia are prone to serious manifestations at the onset, so parents can choose accordingly according to their children’s situation; 2. Special populations: for example, young women can consider vaccination against human papillomavirus for the purpose of preventing cervical cancer. For example, young women can consider vaccination against human papillomavirus to prevent cervical cancer, while people with chronic underlying diseases and elderly people can consider vaccination against influenza because their immunity is relatively low during the change of seasons, which can easily induce colds; 3. Emergencies: for example, after being bitten by stray cats, stray dogs and other animals that may carry rabies virus, they need emergency vaccination against rabies within 24 hours.
