“You can’t rush to be safe,” said Dr Yvonne Maldonado, a pediatric infectious disease physician who is overseeing the Pfizer-BioNTech trial at Stanford University. Sometimes one dose — or even two — isn’t enough to boost immunity, she says. “It’s not that the first dose doesn’t work, it’s just that you may need more than one or two doses to make sure you get a higher level of protection. And so testing takes time. ”
It’s quite common for young children to need multiple doses of the vaccine to get a large enough benefit, says Dr. Maldonado. The hepatitis B vaccine is given to children as three doses, while the diphtheria, tetanus, and pertussis (DTaP) vaccine usually requires five doses.
Coronavirus pandemic: What you need to know
Some parents have wondered: If the two-dose regimen is effective for children 6 months to 2 years of age, why can’t the FDA approve a vaccine just for that age group? Unfortunately, “it just doesn’t work that way,” says Dr. Levy. “You can’t look at the results after the fact and say, ‘Oh, you know what? We change our mind about how we analyze this. We will split a group and you only need to approve things for this subgroup. ‘”
For the same reasons, parents can’t go to their child’s pediatrician to request a lower dose of the vaccine before it’s approved, Dr. Levy said. Vaccine dosages are carefully reviewed and approved based on risks and benefits for each age group.
The good news is that once a vaccine for children under the age of 5 is approved, the rollout will be much quicker than for adults, Dr. Permar said, as pediatricians’ offices have been set up to receive and vaccination. “I think we’re looking into late spring at this point,” she said.
And there’s still a lot you can do now to protect your family and prepare. If your child is afraid of needles, Start getting ready by teaching them relaxation techniques or reading them relevant books. If you are concerned about how the Covid-19 vaccine will fit into your child’s regular immunization schedule, or if you have questions about potential side effects, discuss them with your pediatrician, Dr. Dr. Langlois said.
And continue to adhere to public health measures like social distancing and face coverings where possible, and get your older kids vaccinated. According to data from Centers for Disease Control and Preventiononly 24 percent of children 5 to 11 years old and 57 percent of children 12 to 17 years of age have been fully immunized.
Dr Langlois said that the coronavirus was still plaguing young children and disrupting their lives, but parents should not give up hope. “We’ll get there,” she said. “Parents, myself included, just need a little more patience.”
