Medical experts debate the use of adult Pfizer COVID-19 vaccine formulation for children

OTTAWA-Parents and children eagerly await approval of Pfizer’s COVID-19 vaccine for children between 5-11 years of age but with little data left, and indications that Canada’s overdoses will not be useful, some in the medical industry wonder why current practices would not apply to the new vaccine.

“If there is no pharmacological cause, if there is no reason why we can not dilute it or use the adult formulation we have, I think we do,” said Jennifer Lake, a pharmacist and associate professor at the University of Toronto.

Lake, along with other pharmacists and doctors, has been asking the question since Canada’s chief medical officer announced the announcement on Friday.

“I do not think it is recommended for multiple reasons to take pediatric doses from adult vials,” said Dr. Theresa Tam in her latest update.

Although Dr. Tam did not go into detail, she noted the new wording.

“We also understand from Pfizer that the wording has changed so this is their kind of mixed generation wording so this is something that needs to be investigated by the regulator,” she added.

Lake agrees that the data must be taken into account by Health Canada and NACI, recognizing the importance of the new wording, but is still hesitant and likens the situation to the merged debate that occurred earlier in the vaccine expansion.

“The company has a confident reason to say that, they sell us more if we do not, this is if the wording changes and they can explain it well, but if they just dilute it more – they are going to tell us to dilute the more – then we can dilute more of what we already have, “Lake stated.

Other physicians call for caution in these discussions even at such an early stage.

“I think we put the carriage before the horse. This kind of thing, what formulation is given, whether the adult formulation is given, all these things will be regulated by the right authorities, I think we should wait for that,” he said. Dr. Sumon Chakrabarti, Physician of Infectious Diseases.

“This is a medical procedure. We want it to go through all the right ways and procedures for this to be approved correctly,” he added.

Ottawa parents say they are convinced the decision will be made, it will be properly reviewed.

“For me, it is when it becomes available that I trust that it has been studied and watched, and I will make sure that I follow it up, but I trust those who run these programs,” said Ottawa parent Grant McSheffrey.

Lake says that no matter what decision is made, it is important to consider time protection for children.

“We should protect school children as soon as possible so that they can stay in school,” she said.

Some parents still say that they are willing to wait if it means getting the right vaccine.

“I will trust that when they provide the guidelines, they have done what they need to do, so if that means we have to wait a little longer to be sure it will be effective and safe, that’s fine,” Ottawa Mom Frankie Nadeau said.
