The paediatric Pfizer COVID-19 vaccine has been demonstrated to reduce COVID-19 in children 5-11 years
of age. Within an ongoing clinical trial evaluating the paediatric Pfizer COVID-19 vaccine in children aged 6
months to 11 years of age, results have been reported for the age group 5 to 11 years.10 Among 2186 trial
participants aged 5 to 11 years without evidence of prior COVID-19 infection, two doses of 10µg of paediatric
Pfizer COVID-19 vaccine were 90.7% effective (95% CI [confidence interval]: 67.7 to 98.3%) at preventing
laboratory-confirmed symptomatic COVID-19 from day 7 after dose 2 (with an interval of 3 weeks between
doses). This was based on 3 observed cases among 1305 paediatric Pfizer COVID-19 vaccine recipients
compared to 16 cases among 663 placebo recipients reported between July and September 2021. The three
cases in the paediatric Pfizer COVID-19 vaccine group were mild and without fever, whereas most cases in
the placebo group had documented fever. Multiple other symptoms were also observed more frequently
among cases in the placebo group. There were no cases of severe COVID-19 in either group. |
