Researchers in the US have developed a new vaccine candidate for TB that could help protect against drug resistant tuberculosis and boost the effectiveness of childhood vaccination. As there are many different types of tuberculosis bacteria, the researchers made the vaccine by combining four proteins ...
To help identify and manage infectious travel diseases, see Travel Medicine and Vaccination and Critical Images slideshow Travel Diseases to Consider Before and After the Trip.

An initial testing of a new type of tuberculosis vaccine, MVA85A, shows it is "safe and stimulates a strong cellular immune response" in adults with or without a previous bacilli Calmette-Guerin (BCG) vaccination, reported Dr. Helen McShane, of the Center for Clinical Vaccinology and Tropical...
It was assumed that new vaccines would be available in 2024, have a 5-year to lifetime duration of protection, 40–80% efficacy, and be targeted at infants (vaccination at birth) or adolescents/adults (vaccination at age 10years, supplemented by catch-up programmes in older adolescents/...
The only licensed tuberculosis (TB) vaccine, Bacillus Calmette Guerin (BCG), fails to reliably protect adolescents and adults from pulmonary TB, resulting in ~1.6 million deaths annually. Protein subunit vaccines have shown promise against TB in clinical
For example, Carl Naeslund in Sweden was puzzled by the reduction in mortality associated with BCG vaccination in the first year of life considering TB being mainly responsible for deaths in children beyond the first year of life. He introduced the term ‘non-specific’ immunity to describe ...
“Each patient is allocated a supervisor and at least 10 people who have close contact to the patient is also taught about the disease. “Besides that, we conduct school health programmes, regular awareness programmes and ensure that every newborn is given vaccination,” he said during a press...
There are several factors that can contribute to false positive test results, in which a person has a positive test result despite not having an infection. Known causes for false positive test results include: Previous vaccination with the bacille Calmette-Guérin (BCG) TB vaccine ...
