The lower prices — $4.50 for Merck’s Gardasil vaccine and $4.60 for GlaxoSmithKline’s Cervarix — were negotiated through the GAVI Alliance, which was created in 1999 with a grant from the Bill and Melinda Gates Foundation to deliver more vaccines to the world’s poor.

Gardasil and Cervarix, given to girls as young as 9, have caused controversy in the United States, where many parents fear side effects and worry that girls will see the vaccines as condoning sex at a young age.

The vast majority of girls in the United States have not been inoculated.
