The United States is to provide health authorities with data on vaccine failures and the spread of infection after the U.K. announced that it would require all vaccine manufacturers to make data publicly available.

The White House on Monday sent a letter to the British government urging the data to be provided, saying it is needed for “continuing discussions on vaccine security and safety.”

British Prime Minister Boris Johnson announced Thursday that the U-K.

would require the manufacturers of the live and injectable HPV vaccine Gardasil to share data on the virus.

Johnson said he hoped to get the data from the manufacturers before March 3.

The U.N. health agency estimates the vaccine will protect 1.6 million girls and women by 2020.

Johnson said the data would help to understand how to prevent the spread.

The U.KS. is the second country in the world to require the data.

Sweden, which requires manufacturers to produce the data on their products, requires all vaccine-maker data be made available to the public.

The data would be used to help determine whether to offer new versions of the vaccine.

The United States has long said the vaccine should be available to all children, including girls.
