The variable vaccine_date records the date of the first vaccination, together with vaccine_name to capture the name of the first vaccine. The WHO T1 toolkit form collects the date of the last dose received, and ISARIC ICC also collects date of most recent dose, unless dates for all doses are available.
Is date of most recent dose more useful than date of first dose, or should separate variables exist for both dates so that one or the other can be populated depending on the data available in the source file?

Capture all documented vaccinations with (approx) date if available and vaccine name.
Amend label of Vaccine_name to Name of vaccine.
Amend label of Vaccination_date to Date of vaccine.
These can be made repeatable fields.

It would be interesting to think about vaccines (and countermeasures) in the context of our G.h 100 days mission.

Is this a (known) pathogen? available countermeasures at Day 0?

I think it makes sense to track separate dates for first versus series versus booster vaccinations, when available.

However, De-identified line-lists make it very hard (if not impossible) to support long-term longitudinal tracking of an individual case.

CDC report on mpox, "The mpox outbreak occurred with little warning,
peaked quickly, and waned 5 months after the first case was
reported in the United States. Even as WHO declared the outbreak no longer a public health emergency on May 11, 2023, a
cluster of mpox cases occurred in Chicago, Illinois, including
among some previously vaccinated persons, demonstrating
the ongoing risk for new cases and outbreaks and the need for
continued vigilance and prevention efforts.¶¶ CDC continues
to focus on surveillance, vaccination, and communication for
populations at risk for mpox as important prevention tools." CDC

Further, "Limited early availability of JYNNEOS vaccine
required careful allocation to facilitate receipt of vaccine by
persons at highest risk for exposure, with eligibility criteria
expanding as additional vaccine supplies became available."

Vaccine (countermeasure) availability and access become tied to health equity - an area that G.h promotes in our Mission. We believe in equitable health research that serves communities of all backgrounds.
"During the outbreak, persons from racial and ethnic minority groups accounted for a large number of cases and severe
outcomes, and a low proportion of persons receiving vaccines.
Concerted efforts to reach affected communities with vaccination events mitigated but did not overcome these disparities."

Recommendation: add vaccination variables as a modular section to the schema (not always relevant to all outbreaks). Allow for collection of records of all doses (repeatable fields), capturing vaccine type/name and date as available. Allow for capture of total number of vaccine doses if individual records are not provided.
