There is hope that in the nearest future a vaccine for Gonorrhoea will be available for use as for the first time, a vaccine has tested positive as some form of protection against the dreaded disease. Scientists in New Zealand who carried out the study, published in the lancet, with 15,000 young people said that results showed infections cut by about a third.

Gonorrhoea is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. Many people have no symptoms. Men may have burning with urination, discharge from the penis, or testicular pain

The news of a possible vaccine is really comforting following a recent publication by the World Health Organisation, WHO, that the infection was fast becoming resistant to available antibiotics. WHO expressed worry as many developing countries have reported that their last resorts no longer worked against the bacteria.

“These cases may just be the tip of the iceberg since systems to diagnose and report untreatable infections are lacking in lower-income countries where gonorrhoea is actually more common,” WHO expert, Teodora Wi, said in Geneva. With over 78 million people affected every year, WHO says that a vaccine might be the last solution to combating the bacteria since antibiotics had failed.

Scientists say that the human body unlike in other infections, does not build resistance no matter how many times a person is infected. According to BBC, the vaccine, originally developed to stop an outbreak of meningitis B, was given to about a million adolescents in New Zealand between 2004 and 2006. Researchers at the University of Auckland analysed data from sexual health clinics and found gonorrhoea cases had fallen 31% in those vaccinated.

The bacterium that causes meningitis, Neisseria meningitidis, is a very close relative of the species that causes gonorrhoea – Neisseria gonorrhoeae. It appears the Men B jab was giving “cross-protection” against gonorrhoea. Dr Helen Petousis-Harris, one of the researchers, said: “This is the first time a vaccine has shown any protection against gonorrhoea. “At the moment, the mechanism behind this immune response is unknown, but our findings could inform future vaccine development.” Protection seemed to last about two years.
