Key Questions
How many measles cases have been reported in the US recently?
Over 2,030 cases and 30 outbreaks have been reported nationwide. Virginia has seen nearly 170 cases statewide, with expansion in areas like Cumberland County.
What changes were made to ACIP vaccine recommendations?
Universal recommendations were removed, and charter changes may delay future guidance. IDSA has criticized the politicization and reduced meeting frequency.
What is the status of the Virginia measles outbreak?
The outbreak has expanded to nearly 170 cases, with alerts issued at three US airports due to rapid spread. Most cases involve children aged 5-17.
What did the FDA recommend for the Moderna mRNA flu vaccine?
The FDA VRBPAC unanimously recommended it for adults 65 and older. Studies show it triggers a stronger germinal center response than traditional vaccines.
What did the suppressed CDC study find about the 2025-26 COVID vaccine?
It reduced emergency department and urgent care visits among immunocompetent adults. The study was later published after internal blocking at the CDC.
How effective are COVID boosters for IMID patients on immunosuppressants?
Boosters significantly reduce hospitalization and death risk, with a dose-response effect showing greater protection from multiple doses.
What did the former CDC chief medical officer say about RFK Jr.?
Dr. Debra Houry stated that RFK Jr. caused irreparable harm to public health trust, with CDC trust dropping from 77% to 50%.
What guidance exists for measles in immunosuppressed patients?
Clinicians should not rely on commercial serology for MMR immunity assessment. Therapy interruptions pose risks for these vulnerable groups.
US 2,030+ cases, 30 outbreaks. ACIP universal recommendations removed. VA measles outbreak expands (129 statewide, Cumberland County). New: measles alerts at 3 US airports underscore rapid spread. New: Measles guidance for GI/hepatologists – don't rely on commercial serology for MMR immunity; therapy interruption risks for immunosuppressed. New: ACIP charter changes may delay vaccine recommendations – IDSA criticizes politicization, reduced meeting frequency, shift of authority to CDC director. New: FDA VRBPAC unanimously recommends Moderna mRNA flu vaccine for older adults (65+) – split regulatory path. WashU study shows mRNA flu vaccine triggers stronger germinal center response. New: COVID-19 vaccine study (suppressed by CDC, now published) shows 2025-26 COVID vaccine reduced ED/urgent care visits among immunocompetent adults. New: Pneumococcal vaccine update for older adults (Capvaxive at 65) from MVEC. Other: RFK Jr. hantavirus quarantine order, ACIP turmoil, ACOG diverges, Trump executive order (realigns childhood vaccine schedule from 17 to 11 core – sparks expert concern from Offit and Carney), VA outbreak expansion, measles airport alerts, meningitis vaccine requirement, KFF poll, VA study on same-day vaccination, UK HPV study. Also: Travel vaccine warnings rising this summer. New: Colorado measles case in unvaccinated teen with international travel – 24th case, mostly in kids 5-17, specific exposure locations (Longmont, Aurora). New: COVID-19 booster significantly reduces hospitalization/death in IMID patients on immunosuppressants (dose-response: one booster aOR 0.56, three boosters aOR 0.20). New: CDC study on influenza vaccine effectiveness against pediatric death over 10 years – vaccination significantly reduces mortality risk, supporting flu vaccine promotion for children. New: Pediatrics commentary on immunization to prevent childhood deaths from influenza – provides clinical context and reinforces flu vaccine importance for children. New: Former CDC chief medical officer says RFK Jr. caused ‘irreparable harm’ to public health trust, with CDC trust dropping from 77% to 50%. This reinforces concerns about vaccine policy politicization and ACIP volatility. New: AAAAI workgroup report on vaccination in immunosuppressed patients – authoritative guidance on vaccine safety and efficacy in vulnerable populations, calls for better trial inclusion and safety surveillance. New: CDC internal suppression of COVID vaccine effectiveness data revealed – acting director blocked publication; study later published shows 2025-26 COVID vaccine reduced ED/urgent care visits. Raises concerns about political interference in vaccine guidance.
