Prototype chlamydia vaccine 'very promising'

21/07/2016

Prototype chlamydia vaccine 'very promising'Chlamydia is one of the most common sexually transmitted infections in the world and, at present, there is currently no approved vaccine for human use, and condoms are the best form of protection.

However, promising new research from Canada published in the journal Vaccine shows that a chlamydia vaccine prototype administered to mice helped the animals fight off the infection.

The team of researchers from McMaster University in Ontario gave the mice two doses of the experimental vaccine via their noses. The animals were then exposed to chlamydia bacteria and the researchers found that the vaccinated mice had fewer instances replicating in their systems.

Furthermore, the vaccinated mice were found to be less likely to get damaged fallopian tubes as a result of being infected with the bacteria.

Prof James Mahony, from the Department of Pathology and Molecular Medicine at McMaster University, said the results were "very promising".

"We will trial the vaccine on other animal models before moving on to human trials," he added.

In 2015, there were more than 200,000 chlamydia diagnoses in the UK alone, and over half of those were in young people aged between 15 and 24.

Chlamydia often doesn't cause any symptoms, so many people do not even know they have it. If left untreated, it can lead to significant long-term health problems, including infertility, which is why this new prototype vaccine is such an exciting breakthrough.
