Adding chemical databases with one hand while public ones close programmatic access with the other.
A side-by-side editorial comparison of admiralvaccine and FedData — release velocity, themes, recent moves, and the top alternatives to consider.
Vaccine ADaM templates exist and are maintained, but development has slowed to housekeeping.
admiralvaccine provides vaccine-specific ADaM templates and vignettes — ADCE, ADFACE, ADIS, ADSL — on top of admiral. The last two releases contain no functional change at all: 0.5.0 is maintainer handover, template fixes and lint config, and 0.6.0 is CRAN documentation compliance plus an ecosystem-wide Ask AI widget. Real work was last visible in 0.4.0's criterion-flag deprecation.
FedData has spent two major versions migrating US federal geodata off R's retiring spatial stack.
FedData downloads and standardises US federal geospatial datasets — NLCD, NHD, NED, SSURGO, Daymet, GHCN, PAD-US, NASS — into consistent R objects. Two breaking majors define the current package: 3.0.0 moved returns to sf and raster and pulled data from cloud-optimised GeoTIFFs, and 4.0.0 finished the job by dropping sp and raster entirely for terra and sf. Recent releases are dataset refreshes, most recently PAD-US 4.0.

Real work was last visible in 0.4.0's criterion-flag deprecation.
The package has moved from building out vaccine domains to keeping them on CRAN. Each release tracks whatever admiral changed upstream and clears whatever CRAN flagged, and the changelogs have shifted from derivation notes to merged-PR lists. Maintainer churn in 0.5.0 is the clearest sign that this is a maintenance-mode package inside an otherwise active ecosystem.
The next release most likely continues the pattern — dependency and documentation alignment with admiral core plus deprecation follow-through — unless a new vaccine reporting requirement forces domain work.

Recent releases are dataset refreshes, most recently PAD-US 4.0.
The package tracks two moving targets at once: the R spatial stack, which it has now fully migrated onto terra and sf, and the federal agencies whose URLs, file naming and hosting keep shifting. With the dependency migration finished, releases have shrunk to single-dataset updates such as annual NLCD and PAD-US 4.0, which suggests the structural work is done and the ongoing cost is data-source maintenance.
Expect continued small releases pinned to new vintages of the underlying federal datasets, plus fixes when an agency moves or reformats a source; no further dependency-level upheaval is visible in these entries.
