New updated COVID vaccines are now available, but who can get them, who should get them, and when? Two updated mRNA COVID vaccines, one by Moderna and the other by Pfizer, have been authorized or approved by the US Food and Drug Administration (FDA) for those aged 6 months or older.

Both vaccines target Omicron's KP.2 strain of the JN.1 lineage. An updated protein-based version by Novavax, also directed at JN.1, has been authorized, but only for those aged 12 years or older.

The Centers for Disease Control and Prevention's (CDC's) Advisory Committee on Immunization Practices (ACIP) recommends a dose of the 2024-2025 updated COVID vaccine for everyone aged 6 months or older. This includes people who have never been vaccinated against COVID, those who have been vaccinated, as well as people with previous COVID infection. Head over to Medscape to read the full story.
