Hepatitis A is endemic in developing countries and it is the most common cause of viral hepatitis among people who visit such areas for travelling or work. Although hepatitis A vaccines are extraordinary immunogenic, vaccine failure may occur. Vaccine failure in travellers is potentially hazardous ...
But it is enough to make your immune system(免疫系统) active.Some vaccines are effective for life, while others wear off(逐渐消失) after a few months or years. Most doctors suggest the following vaccines: measles-mumps-rubella, hepatitis B and chicken pox. After having these vaccines when yo...
How long does the rotavirus vaccine last? How effective is the MMR vaccine? How effective is the measles vaccine? How effective is the chickenpox vaccine? How effective is the hepatitis B vaccine? Is there a vaccine for HBV? At what age is the hepatitis A vaccine given?
The high cost and limited supply of hepatitis B vaccine means that its use should be restricted to those with the greatest attack rate, and to those individuals whose occupational risk is significantly greater than that of the general population. This approach must refer to specific situations whic...
Research into the development of therapeutic HPV vaccines often overlaps with that oftargeted cancer therapies. This is because many of the vaccine candidates aren't designed to attack the virus, but the tumors it causes.11 Among some of the HPV candidates currently under investigation are: ...
a person, the antigens multiply thousands and thousands of times until a raging infection is underway. The vaccine provides just enough of these antigens for the body to recognize them and complete the immune response process, therefore protecting them from exposure to the disease in the future....
The immediate goal is to create vaccines that destroy cancer cells—but some scientists are also testing vaccines that might prevent someone from developing cancer.
Is there a hepatitis C vaccine? There is no hepatitis C vaccine. According to thePathogensarticle, the virus has the genetic ability to make various mutations that are somewhat different from each other, making it challenging to develop an effective vaccine. ...
医生可能会进行一些检查,如肝功能检查、甲胎蛋白、病毒血量以及超声肝脏检查等项目。这些检查能指导临床治疗,包括抗病毒药物的使用。 An effective vaccine against hepatitis B infection is available. 已有有效的乙型肝炎疫苗。 (来源:香港...
These include a lack of effective interventions against certain infections, such as vaccines (for example, there is no vaccine for HIV), curative treatments (for example, there are no curative treatments for hepatitis B) or sensitive testing and diagnostic tools. People could be asymptomatic carrier...
