Parents reported 6 percent of young children were unable to do normal activities after second dose
More than 55 percent of children ages 6 months to 2 years of age had a “systemic reaction,” which is a response beyond the injection site, in response to their first dose of the Pfizer-BioNTech or Moderna COVID-19 vaccines, the CDC said on Sept. 1, and almost 60 percent had a reaction to the second dose of the Moderna vaccine.
While the most common systemic reactions were fatigue, fever, irritability, and crying, parents of more than 6 percent of the children in the study that was referenced said their child was unable to perform normal activities after the second dose of either the Pfizer-BioNTech or Moderna vaccine.
The data was collected by the CDC through a program called V-Safe—a smartphone-based monitoring system that operates through an app that parents download to their phones.
Between June 18 and Aug. 21, parents of more than 10,000 young children reported reactions to the CDC through V-Safe in the seven days after their child received a COVID-19 vaccination.
Parents of 8,338 children ages 6 months to 2 years who’d received the Moderna vaccine reported information through V-Safe, with 55.7 percent of them reporting a systemic reaction after the first dose, and about 58 percent after the second dose. For the Pfizer vaccine, parents of 4,749 children ages 6 months to 2 years submitted reports showing that 55.8 percent of them had a systemic reaction after the first dose and about 47 percent after the second dose of the vaccine.
