American families face confusion this vaccine season as federal health agencies offer guidance that sharply conflicts with recommendations from leading medical organizations.
For the first time, the Centers for Disease Control and Prevention and Department of Health and Human Services are at odds with groups like the American Academy of Pediatrics and American Medical Association on who should get COVID-19 vaccines.
This guide explains why COVID guidance has diverged, explains the key differences, and concludes with an overview of recommended schedules for other vaccines.

So What?
With federal guidance in flux, doctors and patients must decide whom to trust—testing the balance between science, politics, and personal choice.
Why Vaccine Guidance Is So Divided
The confusion surrounding vaccine recommendations stems from changes in public health leadership and policy. Robert F. Kennedy Jr. was confirmed as Secretary of Health and Human Services in February 2025. Secretary Kennedy has a history of vaccine skepticism and has initiated policy changes at federal health agencies.
These actions include workforce reductions at federal health agencies, changes to advisory committees, and modifications to vaccine guidelines.
ACIP Committee Dismissed and Replaced
A pivotal moment occurred in June 2025 when Secretary Kennedy dismissed all 17 sitting members of the Advisory Committee on Immunization Practices. The ACIP has historically served as a nonpartisan body of external medical and public health experts who evaluate scientific data to develop evidence-based vaccine recommendations for the CDC.
The terminated members, who served overlapping terms to ensure continuity, reportedly expressed concerns in medical literature about the impact of the dismissals on institutional knowledge and continuity.
The previous committee was reconstituted with new members. Some of the new appointees have publicly questioned aspects of vaccine policy, which has raised concerns within portions of the medical community about the advisory process.
The traditional process for developing vaccine guidance involved rigorous, transparent review by this independent committee, including public meetings and comment periods. The American Medical Association has criticized the new administration for changing vaccine authorizations “without utilizing its traditional advisory committee and public comment processes.”
CDC Director Dismissed After One Month
Leadership changes extended to the CDC itself. CDC Director Susan Monarez, a Trump appointee confirmed by the Senate, was dismissed less than a month into her tenure. That prompted the immediate resignation of several top career officials at the agency in protest.
Following her removal, Dr. Monarez testified before Congress that she believed she was removed for refusing to compromise scientific integrity and for declining to dismiss career CDC scientists.
During a subsequent Senate hearing, Secretary Kennedy addressed questions about the circumstances of her dismissal. This situation highlighted tensions between political leadership and career public health officials.
Public Trust Falls Along Party Lines
These administrative changes have coincided with shifts in public trust that show partisan patterns.
A January 2025 KFF tracking poll found that the share of adults who trust the CDC “a great deal” or “a fair amount” had fallen to 61%, down from 66% in June 2023. The decline was driven by a nine-percentage-point drop among Republicans, whose trust fell from 48% to 39%.
An Axios/Ipsos poll from June 2025 found overall trust in the CDC at 62%, a drop of nearly 25 points from 88% in March 2020. It revealed a stark partisan divide: 86% of Democrats trust the CDC, compared to only 42% of Republicans.
An August 2025 Pew Research Center survey showed this partisan realignment cutting both ways. While Democratic favorability toward HHS and the CDC has fallen significantly since 2024, Republican favorability has actually increased.
This dynamic has created a situation in which federal agencies and major medical societies sometimes offer different guidance. Some Americans trust the federal agencies under current leadership, while others place greater trust in established medical organizations.
Medical Groups Issue Independent Guidance
The nation’s leading medical organizations have responded with unified opposition. The AMA, American Academy of Pediatrics, American College of Obstetricians and Gynecologists, and dozens of others have expressed “significant concern” over the administration’s actions, with some calling the dismissal of the ACIP an “outrage.”
This widespread backlash from science-based organizations explains why groups like the AAP and ACOG have taken the step of issuing their own independent vaccine guidance for 2025-2026, creating the divided landscape families now navigate.
COVID-19 Vaccine: Competing Recommendations
Central questions for the upcoming season surround the updated COVID-19 vaccine. Manufacturers typically update vaccines to target circulating virus strains.
However, guidance on who should receive vaccines may differ between federal agencies and medical organizations.
Federal Position: Restricted Recommendations
Federal health agencies may issue recommendations that differ from previous years, potentially limiting authorization or recommendations to certain age groups or risk categories.
If the federal government were to restrict recommendations to high-risk groups, this could include individuals aged 65 and older, and those with underlying medical conditions.
The High-Risk Definition Question
A major source of confusion is the definition of “high risk.” The FDA did not provide a specific list of qualifying conditions in its approval. However, the CDC maintains a resource on its website that lists underlying conditions, and this list is quite broad.
It includes common ailments such as asthma, cancer, diabetes, HIV, mental health conditions like depression, obesity, physical inactivity, and smoking. This ambiguity allows the administration to publicly message a restrictive policy while technically leaving the door open for physicians to vaccinate a wide range of patients, shifting the clinical and legal burden onto individual practitioners.
The administration’s stated reason for the change comes from the FDA’s Center for Biologics Evaluation and Research Director Vinay Prasad, who cites a “suggested net harm of ongoing vaccination in low-risk populations,” along with concerns about myocarditis and “multiple thrombotic” risks.
Medical Groups: Evidence-Based Approach
Medical organizations would likely continue issuing recommendations based on their review of scientific evidence.
Children and Adolescents
The American Academy of Pediatrics, which has historically endorsed the CDC’s schedule, released its own independent recommendations for 2025.
The AAP strongly recommends the 2025-2026 COVID-19 vaccine for all infants and children 6 through 23 months of age, citing this group’s continued high risk for severe illness and hospitalization.
A single dose is recommended for children and adolescents 2 through 18 years who are in high-risk groups. This includes those who are moderately or severely immunocompromised, live in long-term care or other congregate settings, or have household contacts at high risk for severe disease.
For healthy children 2-18 not in a high-risk group, the AAP states that the vaccine should be offered, and the decision to vaccinate should be left to parental discretion after a discussion with their pediatrician.
Pregnant Women
The American College of Obstetricians and Gynecologists has forcefully broken with the new federal guidance.
ACOG reaffirmed its strong recommendation for the updated COVID-19 vaccine for all individuals who are pregnant, recently pregnant, lactating, or contemplating pregnancy.
ACOG’s guidance emphasizes that pregnancy itself is a significant risk factor for severe outcomes from COVID-19 and that extensive data show the vaccines are safe and effective for both the parent and the fetus.
Other Adults
The American Academy of Family Physicians recommends that adults ages 19-64 receive one or more doses of the COVID-19 vaccine, and people ages 65 and older receive two or more doses, with the exact number depending on vaccination history and other factors.
Side-by-Side Comparison of Potential Scenarios
| Patient Group | Federal Guidance (HHS/FDA) | Medical Authority Guidance (AAP/ACOG/AAFP) |
|---|---|---|
| Infants & Toddlers (6-23 months) | Not authorized or recommended | Recommended for all |
| Healthy Children & Teens (2-18 years) | Not authorized or recommended | Optional, based on shared decision-making |
| High-Risk Children & Teens (2-18 years) | Recommended (if they have a qualifying condition) | Recommended |
| Pregnant & Lactating Individuals | Not recommended (if otherwise healthy) | Strongly Recommended for all |
| Healthy Adults (19-64 years) | Not authorized or recommended | Recommended (1 or more doses) |
| High-Risk Adults (19-64 years) | Recommended (if they have a qualifying condition) | Recommended (1 or more doses) |
| Adults (65+ years) | Recommended | Recommended (2 or more doses) |
Practical Considerations to Access
The new federal policy effectively pushes vaccination of healthy individuals into an “off-label” category, creating significant practical barriers.
Pharmacy Restrictions
Pharmacy regulations vary by state. In some states, pharmacists may be limited in their ability to administer vaccines without broad federal recommendations or prescriptions. Some states may modify their regulations to expand pharmacist authority.
In response, some states, including New Mexico, Massachusetts, and New York, have issued emergency orders to allow pharmacists to administer the COVID vaccine to anyone who wants it, creating a confusing patchwork of access rules that vary by state.
Insurance Coverage Issues
Federal law generally requires insurance plans to cover vaccines recommended by the ACIP at no cost. If federal recommendations become more limited, this could affect coverage requirements, though specific impacts would depend on policy details and state laws.
Access to vaccines may vary based on factors including health care access, insurance coverage, and state regulations. A motivated and well-resourced individual may still be able to get the vaccine by scheduling a doctor’s appointment and paying the full cost.
However, an individual with fewer resources – lacking a primary care physician, unable to take time off work for an appointment, or unable to afford the out-of-pocket cost – s effectively blocked from access. This transforms a public health tool intended for universal benefit into a consumer good available primarily to those with the means to navigate the new barriers.
Routine Vaccines Remain Stable
The comprehensive childhood and adult vaccine schedules continue to protect against a wide range of diseases.
The fact that this comprehensive schedule remains largely intact underscores that the current upheaval is highly targeted, suggesting it is driven more by political ideology around COVID-19 than by a broad scientific re-evaluation of all vaccines.
Infant and Child Vaccines
The 2025 recommended schedule continues to protect against a wide range of diseases. It includes routine vaccinations for Hepatitis B, Rotavirus, Diphtheria, Tetanus, & acellular Pertussis, Haemophilus influenzae type b, Pneumococcal conjugate, Polio, Measles, Mumps, Rubella, Varicella (chickenpox), Hepatitis A, Tetanus, diphtheria, acellular pertussis, Human Papillomavirus, and Meningococcal disease.
States set their own immunization requirements for school attendance, which are generally based on this schedule.
Key Updates for 2025
Influenza: All seasonal flu vaccines are now trivalent, meaning they protect against three flu strains instead of four. A cell-culture inactivated influenza vaccine has been added as an option. The recommendation remains for one dose annually for most children, with two doses spaced four weeks apart for children ages 6 months through 8 years who are receiving it for the first time.
While the new ACIP has expressed a preference for thimerosal-free flu vaccines for children and pregnant women, the AAP maintains that any licensed, age-appropriate vaccine should be used to ensure protection.
RSV (Respiratory Syncytial Virus): To protect vulnerable infants from severe RSV, there are two strategies. The first is maternal vaccination with Abrysvo during pregnancy. The second is administering a monoclonal antibody product directly to the infant.
This includes nirsevimab or the newly approved clesrovimab. One dose is recommended for all infants aged 8 months or younger who are born during or entering their first RSV season. For infants born during the season (typically October through March), administration is recommended within the first week of life.
Polio: The schedule has been updated to explicitly recommend catch-up vaccination for anyone under 18 whose series is incomplete.
Dengue: The dengue vaccine is now recommended only for children ages 9-16 who live in endemic areas (like Puerto Rico) and have laboratory confirmation of a previous dengue infection.
Adult Vaccines
The 2025 adult immunization schedule includes several important updates.
Annual and Routine Vaccines
An annual influenza vaccine is recommended for all adults. For those aged 65 and older, high-dose or adjuvanted formulations are preferred.
A Tdap or Td booster for tetanus and diphtheria is recommended every 10 years.
Age-Based Recommendations
Pneumococcal: In a significant expansion, pneumococcal vaccination is now recommended for all adults aged 50 years and older. Previously, the age-based recommendation began at 65. It is also recommended for younger adults with certain chronic medical conditions.
Shingles: A two-dose series of the recombinant zoster vaccine (Shingrix) is recommended for all adults 50 years and older to prevent shingles.
RSV: A single dose of an RSV vaccine is recommended for adults aged 60 and older, based on shared clinical decision-making with a healthcare provider. A new recommendation also advises the vaccine for adults 50-59 who are at increased risk of severe RSV disease.
Other Vaccines: The HPV vaccine is recommended for all adults through age 26, with shared clinical decision-making for those up to age 45. Vaccines for Hepatitis A, Hepatitis B, and meningococcal disease are recommended for adults with specific risk factors.
Understanding Vaccine Science and Safety
In an environment of conflicting information, understanding the basic science behind vaccines and the robust safety systems in place is more important than ever. The persistence of vaccine myths, some decades old, shows that simply presenting data is not enough.
How Vaccines Work
Vaccines function as a training session for the body’s immune system. They introduce a harmless piece of a germ, allowing the body to prepare its defenses without having to get sick first.
Antigen: This is the active ingredient in a vaccine. It’s a harmless “mugshot” of the germ – a killed or severely weakened version of the virus or bacteria, or just a small piece of it like a protein. The antigen cannot cause the disease it’s designed to prevent.
Antibodies: When the immune system sees the antigen, it recognizes it as an invader and creates proteins called antibodies. These are the body’s custom-made “security force,” designed to find and neutralize that specific germ.
Memory Cells: The immune system also creates memory cells – “veteran guards” that remember the antigen. If the real, infectious germ ever enters the body in the future, these memory cells trigger a much faster and stronger response, producing a flood of antibodies to eliminate the threat before it can cause illness.
Different types of vaccines use different strategies to present the antigen. Live-attenuated vaccines (like MMR and chickenpox) use a weakened form of the live virus. Inactivated vaccines (like the polio shot) use a killed version of the virus. Subunit vaccines (like HPV and shingles) use just a specific piece of the germ. mRNA vaccines (like the updated COVID-19 shots) provide the body with temporary instructions to make a harmless piece of the virus itself, which then triggers the immune response.
Safety Testing and Monitoring
Vaccines are among the most rigorously tested medical products in the United States.
Development Process
Before a vaccine is made available to the public, it typically undergoes 10 to 15 years of research and development. This includes extensive laboratory research followed by a multi-phase clinical trial process overseen by the FDA.
These trials test the vaccine’s safety and effectiveness in progressively larger groups of human volunteers, starting with a few dozen and expanding to tens of thousands.
Continuous Monitoring
Safety monitoring does not stop after a vaccine is approved. The FDA and CDC continuously monitor vaccine safety through multiple systems.
One of the most important is the Vaccine Adverse Event Reporting System (VAERS), a national early warning system co-managed by the CDC and FDA. Anyone – a patient, parent, or doctor – can submit a report of a health problem that occurs after vaccination.
Scientists then analyze this data to detect any unusual patterns that might signal a potential safety issue requiring further investigation. Thanks to this robust system, the United States currently has the safest vaccine supply in its history.
Common Questions and Concerns
Are vaccines safe?
Yes. Vaccines are very safe. The most common side effects are mild and temporary, such as soreness, redness, or swelling at the injection site, or a low-grade fever. These typically go away within a few days.
Serious reactions, like a severe allergic reaction, are extremely rare – estimated to occur in about one or two people per million doses – and healthcare providers are trained to manage them immediately. For nearly all children and adults, the disease-prevention benefits of getting vaccinated are much greater than the possible side effects.
Is there a link between vaccines and autism?
No. This question has been the subject of extensive scientific research. More than a dozen large-scale, high-quality studies conducted by different researchers in different countries have all found no relationship between vaccines and autism.
The myth originated from a single, small study published in 1998 that was later found to be fraudulent, and it was fully retracted by the medical journal that published it. The lead author also lost his medical license.
Do vaccines contain harmful ingredients?
Vaccine ingredients serve specific, important purposes. Adjuvants (most commonly aluminum salts) are used to help create a stronger immune response. Preservatives are used in multi-dose vials to prevent dangerous bacterial contamination.
Thimerosal, a preservative containing a form of mercury called ethylmercury, has been a source of concern. However, ethylmercury is processed differently by the body than the more toxic methylmercury (found in some fish) and is cleared from the body quickly.
As a precautionary measure, thimerosal was removed from all routine childhood vaccines in the U.S. in 2001 (with the exception of some multi-dose flu vaccine vials). Since its removal, autism rates have continued to increase, which is another piece of evidence disproving a link.
Some vaccines also contain trace amounts of substances like formaldehyde, but the amount is far less than what the human body produces naturally as part of its normal metabolic processes.
Are too many vaccines given at once?
No. A baby’s immune system is incredibly powerful and is constantly responding to thousands of germs and antigens in their daily environment – from the air, food, water, and objects they touch.
The total number of antigens in the entire childhood vaccine schedule is a tiny fraction of what babies encounter and successfully manage every day. The recommended immunization schedule is designed by scientists and doctors to provide protection as early as possible, when children are most vulnerable to serious diseases.
There is no known benefit to delaying or spreading out vaccines; doing so only leaves a child unprotected and at risk of contracting a preventable disease for a longer period.
