Know the Latest on Updated mRNA COVID-19 Vaccines

You’ll hear more about 2023-2024 COVID-19 that most patients will need one.

Both mRNA vaccines (Moderna, Pfizer-BioNTech) are now monovalent...covering the Omicron XBB.1.5 SARS-CoV-2 variant.

Data show these vaccines are also effective against circulating variants, including EG.5.1 (“Eris”) and BA.2.86 (“Pirola”).

Be aware, the bivalent vaccines are no longer authorized.

Continue to encourage patients to get COVID-19 vaccines.

Advise getting any age-appropriate 2023-2024 COVID-19 vaccine for everyone 6 months and older without contraindication. Both Moderna and Pfizer-BioNTech are authorized down to age 6 months.

Recommend ONE dose of updated COVID-19 vaccine to patients 5 years and older...regardless of prior vaccination.

Advise waiting about 2 months after a bivalent vaccine to give the 2023-2024 vaccine...or about 3 months after a recent COVID-19 infection.

Follow CDC’s Interim Clinical Considerations, especially for patients who are immunocompromised or kids under 5 years.

For instance, give 2 doses of Moderna or 3 doses of Pfizer-BioNTech to healthy, unvaccinated kids age 6 months to 4 years...with at least one dose being the 2023-2024 vaccine.

And recommend that patients who are moderately or severely immunocompromised (taking certain biologics, etc) get at least 3 doses of COVID-19 vaccine, with at least one dose of the 2023-2024 vaccine.

Be aware, COVID-19 vaccines are no longer government-funded and cost about $120 to $130/dose. Expect most payers to cover them at no cost for patients.

Stay tuned. FDA is evaluating an updated Novavax COVID-19 vaccine.
