Handicapping Tuberculosis May Be The Way To A Better Vaccine
2007-08-02 17:08:00
Scientists have produced a genetically altered strain of tuberculosis, that elicits a stronger immune response than the current vaccine, bacillus Calmette-Guérin. The new vaccine improves survival of infected animals and may help put scientists on track to replace BCG, which has been used for nearly a century although it is largely ineffective.

Worldwide Distribution Of Cervical Cancer Virus Is Consistent With Vaccine
2007-08-02 03:08:00
The variety of human papilloma viruses that cause invasive cervical cancer cases worldwide, are largely consistent across continents, according to a new study. This finding means that prophylactic vaccines currently available against these two most prevalent types of human papillomavirus (HPV) ? which can cause cervical cancer ? could prevent about 70 percent of invasive ...

Need For Influenza And Measles Vaccinations In HIV-infected Patients Affirm
2007-07-23 22:07:00
Two new studies emphasize the importance of delivering measles and influenza vaccines to HIV-infected individuals. Scientists studied immune responses to measles vaccine in HIV-infected and uninfected children in Zambia from 2000 to 2004, when measles endemic in a country that still has one of the highest HIV prevalence rates in the world. Measles poses a greater fatality risk in HIV-infected children than in uninfected children. More: continued here

Protecting HIV Patients From Hepatitis B Virus
2007-07-18 21:07:00
As it is not quite clear how HIV patients that don’t respond to the HBV vaccine should be managed, new research has evaluated the immune response of HBV vaccine given intradermally (into the skin) in HIV-infected individuals who failed to respond to two cycles of HBV vaccine given intramuscularly (into the muscle).

Measles Vaccinations Need To Be Repeated To Protect HIV-infected Children
2007-07-18 19:07:00
HIV-infected children may require repeat measles vaccination for protection. Researchers found that only half of the HIV-infected children who survived without antiretroviral therapy maintained protective antibody levels 27 months after receiving measles vaccine. By comparison, 89 percent of children without HIV maintained their immunity, as did 92 percent of the HIV-infected children who were revaccinated ...

From Clinical Cancer Research: Rethinking Therapeutic Cancer Vaccine Trials
2007-07-04 05:07:00
Ongoing therapeutic cancer vaccine trials have yet to show evidence of vaccines spurring a patient’s immune system to shrink tumors — yet patients who receive these vaccines in trials tend to live longer and respond better to subsequent treatment. In the July 1 issue of Clinical Cancer Research , a journal of the American Association for ...

Researchers have patented a strategy for developing a human vaccine to prevent against Human Cytomegalovirus (hCMV) infection and disease. CMV, a type of herpes virus, is the leading viral cause of birth defects and a serious problem in patients with compromised immune systems. The body’s natural immunity doesn’t protect against infection by the virus, estimated ...

Weak Immune Response Critical To Disease That Causes Most Infant Hospitaliz
2007-06-20 04:06:00
For the past four decades, medical science thought it knew how severe RSV infections arose. Scientists blamed an overreaction in the lungs by specific immune-system cells, T lymphocytes (also known as “T cells”), for the most drastic symptoms of infection. But now, researchers have shown that severe RSV infections in the lower respiratory tract actually ...
