▪COVID -19 burden is currently lower than at previous points in the pandemic, however the 
absolute number of hospitalizations and deaths is still high
▪Although hospitalization rates are currently low in some age groups, we have seen rates 
increase in recent weeks and anticipate further increases as we enter respiratory virus season
▪Infants and older adults have the highest COVID -19-associated hospitalization rates
▪Children and adults with no underlying medical conditions still experience severe illness due to 
COVID -19
▪Post -COVID Conditions are common following SARS -CoV-2 infection, decrease with time since 
infection, and have decreased since the start of the pandemic
▪People of racial and ethnic minority groups continue to be disproportionately impacted by 
COVID -19
▪High proportions of underlying conditions may put certain groups at increased risk for severe 
outcomes due to COVID -19Summary

•Randomized 101 patients to monovalent XBB.1.5 containing dose or bivalent BA.4/5 + XBB.1.5 containing dose
•Patients that received the monovalent XBB.1.5 containing dose demonstrated an increase in neutralizing 
antibodies, with similar levels of neutralization across several XBB sub -variants

▪GRADE approach was applied to assess the type and quality of evidence for the 
anticipated benefits and harms of an updated COVID -19 vaccine
▪The PICO question and inclusion/exclusion criteria were intentionally narrow to best 
capture evidence most applicable to what can be anticipated from this year’s vaccine 
dose in the U.S., including limiting evidence to U.S. studies of an updated vaccine 
formulation (i.e., bivalent mRNA vaccine)
▪Two separate PICO questions were evaluated based on dosing cut -offs 
▪These narrow criteria reduced the number of studies available in the body of evidence, 
however this GRADE assessment builds upon a large body of evidence from the original 
monovalent vaccinesGRADE

–Myocarditis rates following booster doses in adolescent and young adult males are lower than rates 
following primary series , but estimates are limited by fewer numbers of doses for both the bivalent 
boosters and the previous monovalent boosters administered in VSD1
▪Myocarditis risk lower with longer time between doses 
–Rates of myocarditis lower with extended interval between dose 1 and dose 2 for primary series2
–Longer interval between updated doses may also impact myocarditis rates
▪Most individuals with myocarditis/pericarditis have fully recovered at follow -up3

Domain Equity Question:
Are the desirable and undesirable anticipated effects 
demonstrated across all populations equally?

▪There is no evidence to suggest that COVID -19 vaccine effectiveness varies substantially 
by race/ethnicity1,2
–Differences in vaccine hesitancy/uptake, crowding, access to care, and prior infection 
could impact vaccine effectiveness and these factors may also differ by race/ethnicity 
▪There is no evidence to suggest that COVID -19 vaccine safety profiles vary by 
race/ethnicity, however risk has been shown to differ by age and sex
–Risk for myocarditis is highest in adolescent and young adult males
▪Benefits and harms for the U.S. population are best assessed when clinical trial and 
study populations are optimally representative of the U.S. population Are the desirable and undesirable anticipated effects 
demonstrated across all populations equally?

▪Monovalent XBB containing COVID -19 vaccines increase the immune response against the currently 
circulating variants 
▪Last year’s updated vaccine was effective at preventing medically attended COVID -19, hospitalization 
due to COVID -19, and death due to COVID -19
▪Accumulating evidence that COVID -19 vaccination reduces Post -COVID Conditions among both children 
and adults
▪COVID -19 vaccines have a high degree of safety
–Rare events of myocarditis and anaphylaxis have been seen in post -authorization studies 
–Unlikely that updating the formulation would increase adverse event rates
▪Benefits are anticipated in all age groups; benefits of COVID -19 vaccines vary by ageand incidence of 
COVID -19 hospitalizations
▪Benefits outweigh risks in age groups for which risk of myocarditis is highest
▪Modeling projects more hospitalizations and deaths averted when updated doses are universally 
recommended compared to no recommendation or recommended only for persons ≥65 yearsSummary

▪Vaccines with a monovalent XBB.1.5 composition will be the first COVID -19 vaccines to 
be available directly from the manufacturers as part of the commercial market, rather 
than through the United States Government (USG)
▪The public will continue to be directed to Vaccines.gov to find providers offering COVID -
19 vaccine
▪While providers will no longer be required to report inventory to Vaccines.gov after 
vaccines transition to being available on the commercial market, they will continue to 
be encouraged to report voluntarily
–Providers are also strongly encouraged to report the minimum age (in months and 
years) for whom a location can administer vaccine
▪CDC will continue its efforts to make sure that all people have access to COVID -19

Minority opinion Majority opinion
Summary and Work Group Interpretations  
▪The burden of COVID -19 varies by age and underlying condition status with those ages ≥65 years and 
those with multiple underlying conditions having the highest risk of severe outcomes due to COVID -19
▪COVID -19 burden is currently lower than at previous points in the pandemic, however there are still 
thousands of hospitalizations and hundreds of deaths each week
▪Children and adults ages 5 –49 years had the lowest hospitalization rates overall
–Severe outcomes occur in this age group, including in people with no underlying medical conditions
▪Although hospitalization rates are currently low, we have seen rates increase in recent weeks and 
anticipate further increases as we enter respiratory virus season
▪Majority of U.S. population has some level of immunity due to infection, vaccination, or both
–Vaccine and infection -induced immunity wane and new variants have emerged, suggesting that
susceptibility remains and may increase over time
▪Racial and ethnic minority groups have been disproportionately affected by COVID -19Summary and Work Group Interpretation: 
Public Health Burden
122
▪Monovalent XBB containing COVID -19 vaccines increase the immune response against the currently 
circulating variants 
▪Last year’s updated vaccine was effective at preventing medically attended COVID -19, hospitalization 
due to COVID -19, and death due to COVID -19
▪COVID -19 vaccines have a high degree of safety
–Unlikely that updating the formulation would increase adverse event rates
▪Benefits are anticipated in all age groups; benefits of COVID -19 vaccines vary by age, and incidence of 
COVID -19 hospitalizations
▪Benefits outweigh risks in age groups for which there is a risk of myocarditis
▪Modeling projects more hospitalization and deaths averted when updated doses are universally 
recommended compared to no recommendation or recommended only for persons ≥65 yearsSummary and Work Group Interpretation:
Benefits and Risks
123
▪Work Group considered non -universal policy options, with considerable discussion around the magnitude of benefits in 
the young, healthy population
▪As part of these deliberations, Work Group requested additional data on severe illness due to COVID -19 in those with 
and without underlying conditions
–No group that clearly had no risk of severe illness
–The vast majority of the US population has an underlying condition that would qualify under a risk based 
recommendation
•Prevalence of overweight and obesity alone is >70% of adults1
–Risk based recommendation would not allow access to COVID -19 vaccines for all that wanted them 
▪Shared clinical decision making could create barriers to vaccination and may not effectively target those at highest risk
▪COVID -19 epidemiology remains uncertain and non -universal recommendations would need to be quickly revisited if 
there was an increase in burden
▪Still substantial COVID -19 disease burden and simple, stable recommendations may increase vaccine coverage over time
▪Work Group emphasized that COVID -19 recommendations should be reviewed on an ongoing basis as more is learned 
about COVID -19 seasonality and disease burden in the futureSummary and Work Group Interpretation:
Considerations Regarding a Universal vs. Non -universal Policy
1National Health Statistics Reports; https://stacks.cdc.gov/view/cdc/106273124
▪Burden of severe illness due to COVID -19 is lowest among children ages 5 –17 years
▪Despite lower burden relative to other age groups, hundreds of deaths due to COVID -19 occurred in this 
age group in 2021 and 2022
–Half of pediatric COVID -19 deaths were in individuals with no underlying conditions
▪Number of COVID -19 hospitalizations and deaths in this age group are comparable to the burden seen in 
other vaccine preventable diseases for which there are universal recommendations
▪Potential additional benefits of vaccination , such as prevention of post -COVID conditions and potential 
for reduced school absenteeism 
▪Risk of myocarditis appears lower than the risk observed following primary series doses
–Potentially lower due to increased interval between doses
–Certainty is limited by relatively lower sample size of booster recipients in VSD
▪Future COVID -19 epidemiology remains uncertain and the low disease burden we are currently seeing 
may not last
▪After a robust discussion, Work Group was supportive of a universal recommendation at this timeSummary and Work Group Interpretation:

▪Everyone aged 5 years and older are recommended get one 2023 –2024 COVID -19 
vaccine to be up to date.
▪Children aged 6 months –4 years and people who are moderately or severely 
immunocompromised need multiple doses, including at least one 2023 –2024 COVID -
19 vaccine dose to be up to date. 
▪People who are moderately to severely immunocompromised may get additional doses 
of the 2023 –2024 COVID -19 vaccine.Proposed 2023 –2024 COVID -19 Vaccine Up to Date 
Definition
Simultaneous administration of 
COVID -19 and other vaccines
▪In accordance with General Best Practice Guidelines for Immunization , routine 
administration of all age -appropriate doses of vaccines simultaneously (i.e., 
administering more than one vaccine on the same clinic day or “coadministration”) is 
recommended for children, adolescents, and adults if there are no contraindications at 
the time of the healthcare visit. 
–Providers may simultaneously administer COVID -19, influenza, and respiratory syncytial virus (RSV) vaccines to 
eligible patients; the Health Alert Network (HAN) published on September 5, 2023 may be consulted for 
additional information about simultaneous administration of these vaccines.
–Simultaneous administration of COVID -19 vaccine and nirsevimab (a long -acting monoclonal antibody for certain 
infants and young children for prevention of RSV) is recommended
–Coadministration of COVID -19 and RSV vaccine for older adults is acceptable
–There are additional considerations if administering an orthopoxvirus vaccine and COVID -19 vaccine Simultaneous administration of COVID -19 and other vaccines
