I'd like a fact check on this claim. Can someone provide reliable information on how vaccination status is recorded for Covid-19 deaths?
The claim: The CDC is classifying deaths in a misleading way
The implication: They are deliberately falsifying information, we can't trust the scientific consensus on vaccines
But is this claim true? Can we trust the sources that are making this kind of claim?
Mennonitemom, Josh - you have each made this claim. Do you have reliable sources to back it up?

I was looking for a place to leave some info I read today... this seems as good a place as any.... and anyone can look into this for themselves....
IF someone dies within 2 weeks of being vaccinated, (which MANY ARE) they are counted as "unvaccinated" by the cdc....

CDC counts them as “unvaccinated” until 6 weeks after the 2nd shot.
Then us unvaccinated people get blamed for every death of such a vaccinated person.
Israel reported the data accurately with a “partially vaccinated” category.
I would vote to mark the claim as "Mostly True."
Take this
Morbidity and Mortality Weekly Report from the CDC for instance.
Summary
What is already known about this topic?
The incidence of SARS-CoV-2 infection, hospitalization, and death is higher in unvaccinated than vaccinated persons, and the incidence rate ratios are related to vaccine effectiveness.
What is added by this report?
Across 13 U.S. jurisdictions, incidence rate ratios for hospitalization and death changed relatively little after the SARS-CoV-2 B.1.617.2 (Delta) variant reached predominance, suggesting high, continued vaccine effectiveness against severe COVID-19. Case IRRs decreased, suggesting reduced vaccine effectiveness for prevention of SARS-CoV-2 infections.
What are the implications for public health practice?
Getting vaccinated protects against severe illness from COVID-19, including the Delta variant. Monitoring COVID-19 incidence by vaccination status might provide early signals of potential changes in vaccine effectiveness that can be confirmed through robust controlled studies.
This report summary refers to two groups - "vaccinated persons" and "unvaccinated persons."
Now let's move down to the body of the report, where we find phrases such as the following (bolded emphasis mine).
percentage of vaccinated persons among cases (PVC) and an IRR between unvaccinated and vaccinated patients
Most jurisdictions focus on assessing COVID-19 outcomes in fully vaccinated persons (≥14 days after completion of all recommended doses of an FDA-authorized COVID-19 vaccine) and have readily implemented comparisons to not fully vaccinated persons, including persons who are partially vaccinated (<14 days since completing the primary series or did not complete the series) or unvaccinated (did not receive any COVID-19 vaccine); some jurisdictions also monitor trends in partially vaccinated persons.
Only some jurisdictions monitor trends among the partially vaccinated, with the remainder lumping the partially vaccinated with the unvaccinated.
Weekly age-specific incidences by vaccination status were calculated as the number of cases, hospitalizations, or deaths divided by the number of persons either fully vaccinated or not fully vaccinated (obtained by subtracting the number of fully vaccinated persons from total population estimates).
Here again the term "not fully vaccinated" is used, lumping the unvaccinated and partially vaccinated together.
And then the clincher.
The findings in this report are subject to at least five limitations. First, combining unvaccinated and partially vaccinated persons resulted in lower IRR and VE estimates.
The report does include a link to a sensitivity analysis that attempts to somewhat quantify the effect of combining these two groups. However the claim that the CDC is combining the partially vaccinated and unvaccinated persons categories is basically true.
