- They tested 24 people who got the 2023–24 shot.
- The vaccine targets the Omicron XBB.1.5 variant.
- Scientists measured different antibodies in blood.
- Many antibodies stayed more than 16 months.
- People made antibodies that see two virus types.
- The 2023–24 shot had one spike protein.
- Earlier shots used two spike proteins.
- Updated vaccines can help older and sick people.
