Hepatitis B third injection and the RHD vaccine can usually be given together if the body condition is relatively good; however, if the body condition is relatively poor, it is generally not recommended that the two injections be given in a row. The vaccine should be administered under the judgment of a medical professional to avoid affecting the efficacy of the vaccine or producing serious adverse reactions. Hepatitis B third shot and the influenza vaccine itself can be given at the same time, as long as they are not given in the same arm, it will not have much effect, but it is generally suitable for people with strong physique, and to ensure that there is no adverse reaction after vaccination. If you have a weak constitution and are prone to adverse reactions or other discomforts after vaccination, it is not recommended that you take the third Hepatitis B vaccine and the RHD vaccine together. It should be known at the time of Hepatitis B vaccination that if there is any allergic condition, or serious chronic disease, the vaccine should be given after the body has recovered to normal. Symptoms such as fever, redness and swelling may occur after receiving the Hepatitis B vaccine and are normal reactions. It is important to know that if you are allergic to any of the ingredients of the vaccine, you should inform your doctor; if you have acute infection or fever, you should postpone the vaccination. After vaccination, there may be temporary fever, local pain and other symptoms, which usually disappear on their own. If you need to receive the third dose of Hepatitis B or Rheumatoid Vaccine, you should do it under the guidance of a professional doctor and consult with him/her before vaccination.
