1,200 children vaccinated against COVID-19 at clinic in Lansdale, Pa.

Millions of doses of Pfizer's pediatric COVID-19 vaccine are being shipped out across the county.
LANSDALE, Pennsylvania (WPVI) -- Inside North Penn High School in Lansdale, Pennsylvania, parents arrived by the hour to have their children vaccinated against COVID-19.

Roughly 1,200 at the clinic Sunday were able to get their first dose of the Pfizer vaccine for children.

"It's been a long wait for these two," said Sarah Lo, who is a parent and doctor at Children's Hospital of Philadelphia.

Lo's children, Jonah and Dalia, were among the last to get vaccinated at the clinic.

"Huge momentous occasion for kids everywhere, so I'm trying not to cry," she said.

At the Skippack Township Municipal Building, about 250 kids age five to 11 gathered with their parents to get vaccinated.

With the approval of the COVID-19 vaccine for children aged 5 to 11, some clinics that have already been busy at work administering initial doses and boosters are now able to make the transition to the younger age group.

"There's millions of kids that are approved to get the vaccine now in the country. And obviously, we are taking care of everyone around the local county, but we're giving people an experience that they want," said Dr. Mayank Amin, owner of Skippack Pharmacy.

Dr. Mak, as he's known to many adults or Superman to the younger crowd, has received 5,000 shots of the Pfizer vaccine for children.

"We've never believed in the model of forcing any child or any parent to get the vaccine, and maybe that's why the world is so receptive to us. Our message is that of love," Amin said.

A love that's been reciprocated in many notes of gratitude to Dr. Mak and his army of volunteers that make these clinics possible.

And word is spreading.

"I thought it was going to be really hard just like when it was approved for adults," said parent Kelleigh Parker.

Some parents, like Parker, are grateful that at least for now those looking for a vaccine can find one.

"It was amazingly simple, surprisingly simple," Parker said.
