On October 14, 2022, I took my ten year old son for a vaccine appointment at a local pharmacy. This was for an updated (bivalent) Moderna COVID-19 booster. I scheduled the appointment online through their websie and selected a slot that specifically stated it was for the updated booster (website text: "Offering COVID-19 Moderna Updated Booster"). The appointment confirmation page also did. I filled out the required form, also explicitly indicating that we were there for an updated COVID-19 booster, and handed it to pharmacy personnel when we arrived. This form should be on file at the pharmacy. Before the vaccine was given, I asked the person administering it whether it was the updated bivalent booster, which he confirmed.  On October 17, 2022, I retrieved my son's vaccine record from the local state vaccine record website. I noticed a complete mismatch between the lot number written on his vaccine card at the pharmacy on October 14, and the lot number listed on the online database.  I called the store and eventually talked to a staff member, the pharmacist who was also the pharmacist on duty when we were there for the vaccination (although she advised me it was an intern who administered the shot). the pharmacist explained to me that a monovalent booster, *not* an updated bivalent booster was given to my son, despite multiple steps of stating and verifying that we were receiving an updated bivalent booster. The lot number on his vaccine card, AR6965B, is for a monovalent booster, which my son was not even eligible for, since his last monovalent booster had been less than five months before. This is the booster the pharmacist states he received. The lot number in the online database, 057F22A, is for an updated bivalent booster.The pharmacist then also advised me that they were not authorized to administer the updated booster on October 14. I was never told this at the time, and the mismatch was not caught by anyone at the pharmacy at any step while we were there. Instead, simply the wrong vaccine was given. Additionally, the bivalent booster was authorized for age 6-11 on October 12. Consequences: - My son received a different vaccine from what we signed up for, from what we stated on the form that was supposed to be reviewed by the pharmacy before vaccine administration, and from what we were directly told he was being given by the vaccine administrator. - My son's health records are now not accurate, for unclear reasons. A vaccine and a lot number different from what he received is on his state health record. This is of concern for multiple reasons (including potential recalls). - My son  unnecessarily suffered common side effects for two days (severe headache, fever, sore and swollen arm and lymph nodes, general malaise), from a vaccine incorrectly given to him that he was not eligible for at the time and was not supposed to receive. - My son now cannot get an updated bivalent booster, which is available and which he is otherwise eligible for, for another two months, because he received a monovalent booster by mistake on October 14. - If we want my son to receive an updated bivalent booster as soon as possible, he will now need to receive one more vaccination in his series than should have been necessary.
