The CDC updated their weekly Covid-19 vaccination dashboard (www.cdc.gov/covidvaxview...), the weekly flu vaccination dashboard (www.cdc.gov/fluvaxview/d...), and the weekly RSV vaccination dashboard (www.cdc.gov/rsvvaxview/d...).

The CDC's Division of Laboratory Systems quality and safety page has reappeared after being MIA since last fall: www.cdc.gov/laboratory-s...

The CDC's handbook to ACIP workgroups for assessing the certainty of evidence has reappeared online: www.cdc.gov/acip-grade-h.... It has been largely offline since last fall.

The CDC did a lot of reorganizing of their developmental monitoring pages, for example: www.cdc.gov/wic-guide/ph.... But I leave it to those with expertise in this domain to say if these are substantive changes or not.

The CDC's flu vaccination dashboard was updated earlier this week: www.cdc.gov/fluvaxview/d...

It looks like the CDC has launched a couple of new pages on human coronaviruses: www.cdc.gov/human-corona... and www.cdc.gov/human-corona...

The CDC updated their "types of Covid-19 Treatment" page at: www.cdc.gov/covid/treatm.... They changed the "people who are more likely to get very sick" section from 65 and older to 75 and older. They also removed dead links to aspr.hhs.gov/COVID-19/Tre... and aspr.hhs.gov/COVID-19/The...

Next comes a couple of pages about the CDC and mpox that have a horse-and-pony show vibe. Like this one about their public health strategy: www.cdc.gov/monkeypox/ph.... And this about page, which has a new section about how actively involved the CDC is. www.cdc.gov/monkeypox/ab...

Also on the topic of mpox vaccines, the CDC updated their page on JYNNEOS vaccine: www.cdc.gov/monkeypox/hc... and how to handle administration errors: www.cdc.gov/monkeypox/hc...

The CDC has deleted a page about mpox research that used to live at www.cdc.gov/monkeypox/ph.... They have also deleted a page about mpox case definitions that used to live at www.cdc.gov/monkeypox/hc.... They updated their mpox vaccine considerations page at www.cdc.gov/monkeypox/hc...

The CDC updated the Traveler-Based Genomic Surveillance Data page at www.cdc.gov/traveler-gen...

The CDC's yellowbook page for chikungunya was updated: www.cdc.gov/yellow-book/...

Also, the CDC's Center for Forecasting and Outbreak Analytics has a measles outbreak simulator?!? And it is down??? From www.cdc.gov/cfa-modeling...: "The server for the Measles Simulator is down for maintenance and expected to be back online soon."

Many changes to the CDC's Center for Forecasting and Outbreak Analytics: the epidemic estimates at www.cdc.gov/cfa-modeling...; and the Covid hospital admissions forecast at www.cdc.gov/cfa-modeling...

The CDC is retiring its Good Laboratory Practices for Molecular Genetics Testing course: www.cdc.gov/lab-training.... It also seems to be ending its PACE continuing education credits for some other courses: www.cdc.gov/lab-training..., www.cdc.gov/lab-training...

The CDC changed lots of their mpox materials. See www.cdc.gov/monkeypox/te..., www.cdc.gov/monkeypox/ca..., www.cdc.gov/monkeypox/ca..., www.cdc.gov/monkeypox/va..., www.cdc.gov/monkeypox/ph... and www.cdc.gov/monkeypox/tr...

After being offline for a month, the CDC made their "vaccination success framework" for partner programs page available again. They made lots of tweaks and removed their program "contact us" section. I guess they don't want to hear from partners any more? www.cdc.gov/success-fram...

The flu vax dashboard was updated: www.cdc.gov/fluvaxview/d... and www.cdc.gov/fluvaxview/d...

Is this analysis of flu vax coverage for the 2024-2025 season new? It is certainly new to the Wayback Machine. www.cdc.gov/fluvaxview/c...

This seems to be new respiratory illness vaccination content from the CDC, thought it is an analysis of vaccination settings for the 2023-2024 season. www.cdc.gov/respvaxview/...

This seems to be a new CDC page? Or maybe it already existed, but just got moved to a new url? www.cdc.gov/cfa-qualitat...

Similarly, the link to the immunization schedule for adolescents 7 to 18 disappeared off www.cdc.gov/vaccines/imz...

On the CDC's immunization page for children and adolescents for health care providers (www.cdc.gov/vaccines/hcp...) they removed the link to the adolescent schedule, formerly at www.cdc.gov/vaccines/imz.... The underlying content disappeared in Dec 2025; the link redirects to the child schedule.

I know that there’s a lot going on, but I hope journos are pulling the threads on Operation PARRIS. This is the first I’ve heard about this, and it blows my mind.
