The case for pneumococcal vaccination of infants
Although the Canadian National Advisory Committee on Immunization recommends that children receive the new pneumococcal vaccine PCV7 beginning at 2 months of age, provincial implementation of the recommendation has been slow. The vaccine protects against infections that result in pneumonia, otitis media, meningitis and other diseases. In Alberta, however, the vaccine is a publicly funded service. (2005-11-07)

An HIV vaccine is within reach
An effective, affordable, and accessible HIV vaccine is 7-10 years away, according to scientists at the Medical Research Council of South Africa, in this week's BMJ. However, its success depends on a complex interplay of politics, science, and public-private partnerships. (2002-01-24)

Vaccinated infants well-protected against severe pneumococcal infection in Norway

University of Guelph researcher develops 3-in-1 vaccine against traveller's diarrhea
A U of G Prof. has discovered a novel approach to developing a first-ever vaccine for three common pathogens that cause traveller's diarrhea and kill more than 100,000 children living in developing countries each year. The vaccine yokes together proteins from pathogenic E.coli with sugars from Shigella and Camplyobacter jejuni -- three bugs that are major causes of bacterial diarrhea globally. Currently no licensed vaccines exist against any of these pathogens. (2018-10-10)

Unruly T cells complicate the intended benefits of HIV vaccines
Inducing strong responses from T helper (TH) cells -- long seen as a desirable goal for HIV vaccines -- and using multiple antigens can hamper the effectiveness of vaccine candidates for HIV, according to an analysis of macaque experiments and a multicenter, phase 1 trial. (2019-11-20)

Protecting HIV patients from Hepatitis B virus
As it is not quite clear how HIV patients that don't respond to the HBV vaccine should be managed, new research from the University of Alberta 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). (2007-07-17)

How HIV vaccine might have increased odds of infection
In September 2007, a phase II HIV-1 vaccine trial was abruptly halted when researchers found that the vaccine may have promoted, rather than prevented, HIV infection. A new study by a team of researchers at the Montpellier Institute of Molecular Genetics in France shows how the vaccine could have enhanced HIV infection. The study, lead by Matthieu Perreau, will be published online on Nov. 3 of the Journal of Experimental Medicine. (2008-11-03)

Safety and supply issues around an H1N1 vaccine
An editorial in this week's Lancet says that countries must have strong post-marketing surveillance in place forthcoming H1N1 vaccines, since countries fast-tracking the approval could bypass the usual safety and efficacy requirements.

Study provides new clues for designing an effective HIV vaccine
New insights into how a promising HIV vaccine works are provided in a study published by Cell Press January 10th in the journal Immunity. By analyzing the structure of antibody-virus complexes produced in vaccine recipients, the researchers have revealed how the vaccine triggers immune responses that could fight HIV-1 infection. The study could help guide efforts to increase the vaccine's production, which currently is not high enough for clinical use. (2013-01-10)

Facebook posts help facilitate belief that HPV vaccine is dangerous to health
Social media has a history of being a popular place for sexual health discussions, and the HPV vaccine is one of the most discussed vaccines on the internet. Monique Luisi, an assistant professor in the University of Missouri School of Journalism, suggests some HPV vaccine-related Facebook posts can help facilitate beliefs that the HPV vaccine is dangerous to one's health. She believes it could inform officials for the ongoing COVID-19 vaccine roll out and distribution. (2021-01-05)
