Pneumococcal Vaccines in Patients With Asthma

Patients will be randomized into either PCV13 and PPSV23 (Experimental) or PPSV23 alone (Active comparator). At the Week 0 time point, the patients will receive either PCV13 (Experimental) or PPSV23 (Active comparator) and undergo a blood draw of 5ml for assessment of pre-vacation serotype titers. The Active Comparator group will ...

Immunogenicity and Safety of Fractional Doses of Yellow Fever Vaccines (YEFE)

Yellow fever (YF) is a mosquito-borne viral disease that is endemic in 34 countries in the African region and 14 in South America. YF virus infection can be asymptomatic or cause a wide spectrum of disease, from mild symptoms to severe, potentially lethal illness with jaundice, renal failure and haemorrhage. ...

Patch Study - Intervention for HIV Positive Smokers

The overall objective of the transdisciplinary team of Human Immunology Virus (HIV) and Tobacco funded researchers is to test if tailoring nicotine replacement doses to temper these excessive levels will enhance the efficacy of the intervention. This will be accomplished by assessing: 1) pre-trial plasma levels, 2) doing genotyping, which ...

Using Less Neurotoxic Drugs in Patients With HAND (MARAND-X)

Scientific Rationale for Study / Scientific Study Objectives: Neurocognitive disorders are still highly prevalent in the HAART era; despite a dramatic reduction in dementia cases, 15-50% of patients may develop mild or asymptomatic neurocognitive disorders (HIV-associated neurocognitive disorders, HAND). It should be highlighted that patients presenting no abnormalities in everyday ...

Switching From Tenofovir Disoproxil Fumarate to Abacavir or Tenofovir Alafenamide

The majority of HIV-1 infected patients in resource rich countries receive the tenofovir prodrug tenofovir disoproxil fumarate (TDF) as part of their combination antiretroviral therapy (cART). Long-term exposure to TDF can be associated with an accelerated estimated glomerular filtration rate (eGFR) decline and proximal renal tubular dysfunction (PTD, see definition ...

Phase

Immunogenicity of Co-administered Yellow Fever and Measles Mumps and Rubella (MMR) Vaccines

The World Health Organization (WHO) and the Pan American Health Organization recommend that yellow fever and measles, mumps and rubella (MMR) vaccines be administered on the same day or at least 4 weeks apart to prevent interference between live vaccines. In 2011 a Brazilian study demonstrated lower seroconversion against yellow ...

Phase

Induction of Immunity Against Measles in Pediatric Liver Transplant Recipients

Eligible children in Group 2 will receive a standard dose (0.5 ml) of MMR vaccine during the first medical visit (V1). The lot number and the expiration date will both be recorded on the patient's case report form (CRF). A serological evaluation 4-8 weeks after MMR will identify children requiring ...

Ketotifen as a Treatment for Vascular Leakage During Dengue Fever

Approximately 230 million individuals are infected each year by dengue virus (DENV) a Flavivirus spread by mosquito vectors that causes substantial worldwide morbidity and mortality. Infection by DENV results in dengue fever (DF), which is usually a self-limiting illness. However, many individuals can experience much more severe forms of disease, ...

Phase

Adjuvanted Inactivated Vaccine Versus Inactivated Influenza Vaccine in Hutterite Children

This study is a randomized controlled trial (RCT) comparing adjuvanted influenza vaccine (AV) to unadjuvanted inactivated influenza vaccine (IIV). Children in Hutterite colonies in Alberta and Saskatchewan will receive AV or IIV. The goal of this study is to determine whether the AV vaccine, can provide increased community-wide protection.

Phase

Safety and Immunogenicity of Measles Vaccine Varicella Vaccine and Hepatitis-A Vaccine

Measles vaccine (MV) can reduce childhood mortality and is currently recommended to all South African children aged 6 months. Only one study has examined the safety and immunogenicity of the recommended CAM-70 measles vaccine strain in children under 9 months of age. In addition, there are limited data on the ...
