That’s not what it says: **CDC recommends one updated (bivalent) booster dose:** - For everyone **aged 5 years and older** if it has been at least **2 months** since your last dose\*\*.\*\* The recommend _one_ booster dose at least two months after your last non-Bivalent shot, not a dose every 2 months. ---

The CDC page is clear as mud to me: **CDC recommends one updated (bivalent) booster dose:** - For everyone **aged 5 years and older** if it has been at least **2 months** since your last dose\*\*.\*\* - **For children aged 6 months** – **4 years** who **completed the Moderna** primary series and if it has been at least **2 months** since their last dose. Last dose? Of bivalent booster or original vaccine? ---

Yeah, I am certain they MEANT you need to get the bivalent booster once, but that may not be what they wrote. ---

Have to agree that that needed to be written much more clearly than it was. ---

Yeah. Because it sounds like they’re recommending boosters every 2 months. ---

I’m glad I am not the only one that struggled with the wording on the CDC website. That confusion is what prompted my original posting of the question. ---

Costco pharmacist said one booster a year unless a new formula comes out. He also said that recommendation could change any second. ---

Mass General Hospital is doing a study on this. If you’re healthy, once a year. If you’re immunocomprpmised, 4-6 months. The study is ongoing so its recommendations will change over time as new variants appear and they get new data. > **[How long will your COVID booster last?
