Developing a vaccine against the human immunodeficiency virus (HIV) poses an exceptional challenge. There are no documented cases of immune-mediated clearance of HIV from an infected individual, and no known correlates of immune protection. Although nonhuman primate models of lentivirus infection have provided valuable data about HIV pathogenesis, such models do not predict HIV vaccine efficacy...
Human immunodeficiency virus (HIV)-infected persons may be important, unrecognized transmitters of measles virus, thwarting eradication efforts. We reviewed the published English-language literature on measles and measles immunization in HIV-infected persons to investigate the clinical features of measles, the responses to measles immunization, and the safety of measles vaccine in HIV-infected ...
Many people are infected with human immunodeficiency virus (HIV) every year. Due to the unique properties of this virus, no effective vaccine has been approved prevent virus. HIV is transmitted a healthy person in various ways, such as sex, using an syringe, etc. So far, ways have proposed spread however, number continues increase Various factors play role process disease transmission.
BACKGROUND Streptococcus pneumoniae is a leading and serious coinfection in adults with human immunodeficiency virus (HIV) infection, particularly in Africa. Prevention of this disease by vaccination with the current 23-valent polysaccharide vaccine is suboptimal. Protein conjugate vaccines offer a further option for protection, but data on their clinical efficacy in adults are needed. METHOD...
HIV-1 Tat-based vaccines: an overview and perspectives in the field of HIV/AIDS vaccine development.
The HIV epidemic continues to represent one of the major problems worldwide, particularly in the Asia and Sub-Saharan regions of the world, with social and economical devastating effects. Although antiretroviral drugs have had a dramatically beneficial impact on HIV-infected individuals that have access to treatment, it has had a negligible impact on the global epidemic. Hence, the inexorable s...
BACKGROUND A safe and effective vaccine for the prevention of human immunodeficiency virus type 1 (HIV-1) infection is a global priority. We tested the efficacy of a DNA prime-recombinant adenovirus type 5 boost (DNA/rAd5) vaccine regimen in persons at increased risk for HIV-1 infection in the United States. METHODS At 21 sites, we randomly assigned 2504 men or transgender women who have sex ...
Acquired Immunodeficiency Syndrome (AIDS) is one of the most critically acclaimed endemic diseases, caused by two lentiviruses HIV-1 and 2. HIV-2 displays intimate serological and antigenic resemblance to Simian Immunodeficiency Virus (SIV) along with less pathogenicity, lower infectivity and appreciable cross reactivity with HIV-1 antigens. The present era is confronted with the challenge to f...
BACKGROUND One of the big roadblocks in development of HIV-1/AIDS vaccines is the enormous diversity of HIV-1, which could limit the value of any HIV-1 vaccine candidate currently under test. METHODOLOGY AND FINDINGS To address the HIV-1 variation, we designed a novel T cell immunogen, designated HIV(CONSV), by assembling the 14 most conserved regions of the HIV-1 proteome into one chimaeric ...
Immunization is an important measure to protect HIV-infected children and adults against certain vaccine preventable diseases. However, the antibody response, which is associated with the level of CD4+ T cell count, is frequently impaired in this group of patients. Certain vaccines enhance virus replication and transiently increase HIV viral load. Theoretically, vaccination should be given befo...
BACKGROUND Phase I and phase II HIV-1 vaccine trials have revealed increases in risky sexual activity among study subjects during the trials, perhaps because the subjects believe that the vaccine being tested is efficacious; subjects may thus suffer harm from their participation. We evaluated the sexual behaviour of Canadian men who have sex with men (MSM) who participated in the phase III Vax0...
