The countries of Japan, the United States and Canada announced Wednesday that they have launched the development of new vaccines that could prevent a deadly coronavirus outbreak that has killed nearly 500 people in Japan, where the outbreak began earlier this month.
The announcement came a day after Japan announced the launch of a vaccine against the virus, which has killed more than 200 people.
The three countries have been struggling to contain the virus for several weeks after the World Health Organization declared the outbreak an international public health emergency.
It is believed to have begun in northeastern Japan in December and spread to northern Japan, and the rest of the country.
The outbreak has killed at least 5,000 people, mostly in Japan.
The World Health Organisation said more than 8,000 cases have been confirmed in Japan since the outbreak started.
Japan has said that the vaccine, which will be available by next week, is one of several vaccines being developed to contain or stop the coronaviruses spread.
The WHO has not said how much the vaccine cost.
The vaccine could be tested in Japanese people and people with severe immune system disorders, such as those who are at risk of severe coronaviral disease.
The countries have not yet released the vaccine’s full specifications, but Reuters reported that the WHO expects the vaccine to be effective in preventing coronavillosis in the first month.
