The Delta variant is now the most dominant strain of the coronavirus in the United States. What does this mean for children, especially those who are too young to be vaccinated? Lurie Children's infectious diseases experts answer common questions.

The vaccine helps protect unvaccinated kids

Although symptoms of the Delta variant are similar to those seen in the original stains of coronavirus, the Delta variant is more transmissible than other variants. Therefore, if unvaccinated, it is easier to catch the Delta variant compared to the other variants. Children may be more likely to get COVID-19 symptoms with this variant, but this has not yet been proven.

"People need to recognize that the COVID-19 pandemic is not over and the Delta variant is known to be more transmissible. It can occur in any age group and especially be a problem in those persons who are too young to be vaccinated or who are unvaccinated," says Dr. Tina Tan, Infectious Diseases physician at Lurie Children's.

While experts and scientists are still looking closely at the data, in general, disease severity with the Delta strain is the same as other strains of COVID. "Remember in most cases, children will have more mild illness," Tan said.

What should parents do if they have children younger than 12?

"What puts children at higher risk is the fact that they are now out and about and often unmasked and unvaccinated. With everything opening back up and more transmissible strains circulating, if community activity picks up, children are a vulnerable population," says Dr. Larry Kociolek, Infectious Diseases physician and associate medical director, Infection Prevention and Control at Lurie Children's.

The majority of Delta variant infections are in those individuals who are unvaccinated. If your child is too young to be vaccinated, Lurie Children's experts recommend continuing with mitigation protocols:

  • Wear a mask: Always keep masks handy and mask up when it’s difficult to keep a safe distance from other people who may be unvaccinated.
  • Socially distance: Remember that some people without symptoms may be able to spread the virus.
  • Practice good hand hygiene: Wash hands properly and often.

As of July 27, the CDC also recommends that people who are fully vaccinated resume wearing masks indoors and encourages everyone in K-12 schools to wear a mask regardless of vaccine status. "We know these methods have worked throughout the pandemic and it should be no different now," Tan said.

Experts also urge all individuals who can get the vaccine to get vaccinated. According to Public Health England, early research is showing that current COVID-19 vaccines are largely effective against disease and hospitalization for the Delta variant. Currently, scientists are researching whether a booster dose will be needed for further protection. For more information on COVID-19 variants, visit the CDC website.
