When Will the COVID-19 Vaccine Be Ready for Kids?

Immunizing kids, nevertheless, is frequently not almost the direct and instant advantages to them. It’s likewise indicated to safeguard kids versus illness that would otherwise end up being more unsafe for them as grownups—measles, mumps, and chicken pox are 3 typical examples—and moisten the total spread of these illness. In the short-term, the main factor to immunize kids versus COVID-19 might be that the U.S. will have a tough time reaching herd resistance otherwise.

Vaccines that work in grownups normally work in kids. However their impacts can vary, specifically in really kids. In newborns, for example, antibodies passed to them in utero can interfere with the protection conferred by the measles vaccine, which is why that vaccine is not given until babies are 12 to 15 months old. An early version of the pneumococcal vaccine did not work well in kids under 2, because it stimulated a part of the immune system that was not yet mature.

Multiple factors determine the recommended age for a vaccination. “For example, when’s the peak incidence of disease? When is a child most likely to respond to the vaccine?” says Cody Meissner, an expert on pediatric infectious diseases at Tufts. The answers to those questions might not align. For instance, the vaccine for HPV, a sexually transmitted virus that can lead to cervical cancer, is given to boys and girls as young as 9 years old because it stimulates a better immune response in preteens than in older adolescents, even though preteens are unlikely to need the defense till later in life.

Even though kids rarely get seriously sick from COVID-19, the vaccine can protect them from an illness that may still be bad enough for them to miss school and their parents to miss work, Jeff Gerber, a pediatrician at Children’s Hospital of Philadelphia, told me. “Even those two-to-three-day illnesses can pile up.” He pointed out that the flu vaccine is recommended for kids, and about the same number of kids died of the flu last season as have died of COVID-19 to date.

But the main argument for broadly vaccinating children is that doing so is likely to reduce COVID-19 transmission. Although schools have not been sources of large outbreaks, many switched to distance learning, and most of those that held in-person classes required masks and distancing. If school buildings reopen without these precautions sometime this year, after adults get vaccinated but while kids are still vulnerable, they will essentially be hosting mass gatherings of unvaccinated people, states Jason Newland, a pediatrician at Washington University. “Guess who’s going to end up having it? All the kids,” he informed me. “And those kids with certain underlying conditions are disproportionately impacted.” What’s more, kids could bring COVID-19 home from school, even if they don’t have actually symptoms. “Children could pass it on to Grandma and Grandpa. They can pass it on to another loved one who has diabetes or has obesity or has chronic kidney disease” and is not yet immunized, Newland stated.
