Vaccine doses or dosages?
Andrew Cuomo, in his popular COVID press conferences, often uses the words “dose” and “dosage” interchangeably (at least so it seems). Here is an example:
“We have the operational capacity to do over 100,000 doses a day — we just need the dosages.”
Here is another:
“To date, New York has administered 2.5 million dosages, with about 10% of New Yorkers receiving their first dose. Ninety-two percent of dosages allocated to the state to date have been used.”
I thought “dosage” refers to the amount in a dose, like x milligrams. A single dosage can have multiple milligrams, so, when you pluralize “dosage,” what exactly are you referring to, if not the number of doses?
