A vaccine to protect people against the regular sexually transmitted infection chlamydia has got over the first tests. It is the first of its kind to enter human trials.

Specialists supposed vaccination might be the most ideal approach to tackle the disease that accounts for almost 50% of all sex infections diagnosed in the United Kingdom.

"More trials must check what dose to give and how well it works", The Lancet Infectious Diseases journal says.

Those tests will take years and in a long time,  and the most ideal way to avoid getting chlamydia during sex is by utilizing a condom.

What is chlamydia?

It is a bacterial contamination that is passed on through unprotected sex (even when there is no penetration).

Chlamydia bacteria stay in semen and vaginal fluid. Regularly, the infected one will have no symptoms, which is the reason people sometimes know it as a "quiet" infection.

In case it isn't treated with antibiotics, it can cause injurious complications and influence fertility.

People under 25 who are sexually active are encouraged to get tested for chlamydia consistently. The NHS offers a free screening service. People can likewise get self-testing packs from pharmacies to do at home with a swab or pee test.

Why do we need a vaccine?

In spite of the fact that antibiotics agents can treat chlamydia, individuals can get the contamination again if they come into contact with it.

Chlamydia remains the most popular STI in spite of screening and successful treatment being available.

Immunization could offer long-lasting protection, experts advise.

In the test, researchers from Imperial College London compared two distinct formulations of the vaccine with a dummy or placebo jab in 35 women.

The two formulations seem to be safe, yet one stood out as a front runner. Now, the researchers want to move this vaccine into the next period of testing.

Investigator Prof Robin Shattock said: "The findings are encouraging as they show the vaccine is safe and produces the type of immune response that could potentially protect against chlamydia.

"The next step is to take the vaccine forward to further trials, but until that's done, we won't know whether it is truly protective or not."

"We hope to start the next phase of testing in the next year to two. If those trials go well we might have a vaccine that can be rolled out in around five years."

He proposed it could potentially be offered with the HPV jab that is recently used to protect against cervical cancer.

One woman from the young people's sexual health and wellbeing charity Brook, said: "Whilst these initial results are promising, it's still very early days and a widely available vaccine could be years in development."
"We would be thrilled to see a vaccine for chlamydia in the future and we are hopeful that this will become a reality."
"As diagnoses of STIs continue to increase national and globally, including antibiotic-resistant gonorrhoea, it remains essential that people use condoms to protect themselves."
