Pfizer tests extra vaccine dose for kids under 5

Pfizer is testing an extra dose of its Covid-19 vaccine for babies and preschoolers after preliminary research hinted the usual two doses wouldn’t be enough.

Pfizer said on Friday it was changing plans and testing three doses of its Covid-19 vaccine in babies and preschoolers after the usual two shots didn’t appear strong enough for some of the children.

Pfizer announced the change after a preliminary analysis found 2- to 4-year-olds didn’t have as strong an immune response as expected to the very low-dose shots the company is testing in the youngest children.
