Data on the real-world effectiveness of vaccines against omicron in children
METHODS
January 21, 2022, through April 8, 2022
Singapore, 5 to 11 years
N= 255,936 children
Fully vaccinated, 67.7% (173, 268)
Partially vaccinated, 12% (30,712)
Unvaccinated, 20.3% (51,995)
16.4 to 17.9 million person-days at risk
53,429 infections
5,342 PCR-confirmed
288 hospitalizations
Among hospitalized children
Five received supplemental oxygen
four of whom, admitted ITU
Of these five children
One was unvaccinated
Two were partially vaccinated
Two were fully vaccinated
No deaths attributable to Covid-19
Among the children in the unvaccinated group
(per 1 million person-days)
All reported infections, 3,303
PCR-confirmed infections, 479
Hospitalizations, 30
Among the children in the fully vaccinated group
All reported infections, 2,770
PCR-confirmed infections, 112
Hospitalizations, 6.6
Vaccine efficacy against hospitalization
Partially vaccinated v unvaccinated children
All reported infections, 13.6%
PCR-confirmed infections, 24.3%

In fully vaccinated children
All reported infections, 36.8%
PCR-confirmed infections, 65.3%
Hospitalizations, 82.7%
Vaccine effectiveness against all confirmed infections
Fully vaccinated v unvaccinated group

7 to 14 days, 48.9 %
15 to 29 days, 37.6%
30 to 59 days, 28.5%
60 days or more, 25.6%
CONCLUSIONS
During a period when the omicron variant was predominant,
BNT162b2 vaccination reduced the risks of SARS-CoV-2 infection and Covid-19–related hospitalization among children 5 to 11 years of age.
these findings suggest greater vaccine effectiveness against higher levels of disease severity,
The results of this study may provide insights to enable decision makers to weigh the benefits against the potential risks of vaccination of children.
In Singapore, 22 serious adverse events after vaccination
(0.005% of all doses administered)
0.05 in 1,000
0.5 in 10,000
5 in 100,000
among children 5 to 11
