Parents will have to wait for a coronavirus vaccine for their young children after Pfizer and BioNTech announced Friday that they are modifying their clinical trial to include a third shot at least two months after the initial two-dose regimen for children under age 5.

The companies reported that two doses of the pediatric vaccine failed in 2-, 3- and 4-year-olds to trigger an immune response comparable to what was generated in teens and older adults. The vaccine did generate an adequate immune response in children 6 months to 2 years old.
