Pfizer Inc.’s Covid-19 vaccine was 73.2% effective against the disease in a trial of children 6 months through 4 years old, reinforcing results that led to the shot’s authorization in young kids in June.
The three-dose regimen was compared with placebo injections during the period when omicron’s BA.2 version was spreading widely from March to June, Pfizer and partner BioNTech SE said Tuesday in a statement. There were 13 cases in a group of 794 vaccinated children and 21 cases among 351 children who received the placebo, the statement said.
