According to a new national poll, many parents said that they are unlikely to get their children vaccinated against COVID-19 due to concerns about the safety and effectiveness of the vaccine.

Both Pfizer and Moderna are conducting vaccine trials for young children and are not expected to be approved until sometime this fall.But the Latest polls Reports from CS Mott Children’s Hospital indicate that many parents are hesitant.

Opinion polls found that 51% of parents with children aged 3-11 said they were unlikely to get them vaccinated. In addition, 40% of parents of children aged 12-18 (currently eligible groups) hold the same view.

70% of parents listed potential side effects as a factor. Another 63% expressed concern about testing in their child’s age group, and 62% expressed concern about efficacy. More than half said that their own research was a factor.

Despite these concerns, many parents—70% of their children are 3-11 years old, and 50% of children are 12-18 years old—have not consulted their children’s primary care physicians about vaccines.

The researchers wrote: “Lack of discussions with pediatricians and other child health providers may put parents at a disadvantage in making informed decisions about COVID vaccination for their children.”

They added that children’s doctors are an important resource for information on side effects and understanding the regulatory procedures for vaccine authorization.

The researchers added: “Parents of young children who have scheduled examinations or who have mild illnesses may wish to include questions about the COVID vaccine in the list of topics discussed during the visit.”

Family income also seems to affect the possibility of parents vaccinating their children. Opinion polls have found that low-income families are unlikely to vaccinate their children.

Moderna announced this week It is expanding its clinical trials in children aged 5 to 11 to better detect potentially rare side effects.

according to New York TimesBecause of concerns about potential rare side effects, including heart inflammation, the U.S. Food and Drug Administration asked Moderna and Pfizer to include at least 3,000 children aged 5-11 years in their vaccine trials.

The US Food and Drug Administration added warning labels to the two vaccines after reporting cases of heart inflammation among some young vaccinators last month.

A Pfizer spokesperson said that it has not updated its trial design or timeline Washington postThe company initially estimated that it will obtain data on children aged 5-11 in September. The trial is designed to include 4,500 children between 6 months and 12 years of age.

The CS Mott Children’s Hospital National Child Health Poll is based on data from a nationally representative sample of 2,019 parents of children aged 3-18.
