The UK’s health minister has warned that it may take some time to develop vaccines to protect people .

Vaccines can take at least a year or 18 months to develop.

Researchers at the University of Oxford have already begun testing the vaccine on humans, but it will take time to see if the vaccine has stopped the infection.

This is especially difficult now because the rate of the corona virus spreading to the general population is now much lower.

Scientists in other parts of the world are also working to develop vaccines.

This is good news, because not all of them will succeed. And even if they do, the world certainly needs more than one vaccine.
