Pediatricians and other experts answer questions about the COVID-19 vaccines.
Pediatrician Ilan Shapiro, MD explains a lower dose of the Pfizer COVID-19 vaccine has been authorized for kids 5-11.
Right now, the vaccine that we have from 5 to 11 is exactly the same formula as the one that we’re giving to the adults. The only difference is that we measure with different doses. Sometimes, kids actually need a higher dose with certain vaccines or medications. Sometimes, actually lower. With this time, we actually saw that we needed one third of the dose of the adult size vaccine. That means that, you know, we needed to measure, you know, if that was effective and safe with all the side effects that we can actually expect. Then very importantly, the side effects were a little bit of pain on the arm, redness, fever, a little bit of malaise that was not happening as often as an adults.
