The Corbevax vaccine was invented at the Center for Vaccine Development at Texas Children's Hospital and intended for countries that couldn't get access to more expensive COVID vaccines. India has inoculated millions of teens with Corbevax (above, a vaccination drive for children ages 12-14 at a school in Bangalore) and on August 10 authorized the vaccine as a booster for adults.
