There is no such thing as a self-funded vaccine that is not recommended. Self-funded vaccines are based on the premise of self-will, and you can judge whether you should be vaccinated or not, taking into account your actual situation. In cases where there is a risk of infection, it is recommended that vaccination be given in a timely manner to avoid increasing the risk of infection or direct infection with related diseases, which may pose a threat to human health. In cases where there is no risk or relatively little risk of infection from related diseases, if you do not feel it is necessary, you can choose not to receive self-funded vaccines, such as the annual influenza vaccine, on your own. If children are vaccinated, they should pay attention to self-funded vaccines such as varicella vaccine, pneumonia vaccine, rotavirus vaccine, hand, foot and mouth disease vaccine, influenza and B encephalitis vaccine, which can provide some protection for children to maintain a healthy body during their growth and reduce the risk of infection in children. At this time, it is recommended that vaccinations be administered in a timely manner when family financial conditions allow. Although there are no self-funded vaccines that are not recommended, there are people who are not suitable for vaccination. People who are allergic to vaccine components or have a history of relatively severe vaccine allergies are usually not recommended to receive self-funded vaccines. In addition, patients with immune system diseases or other chronic diseases that are not under control are also not suitable for self-funded vaccines. It is recommended that vaccinations be actively administered under the guidance of a physician and in accordance with your condition.
