Remember this:

📌 What percent of COVID‑19 deaths were among vaccinated people (late 2021 onward)?

⭐ By late 2021:

About 30% of adults dying of COVID‑19 were vaccinated or boosted KFF.

⭐ By early 2022:

Around 40% of COVID‑19 deaths were among vaccinated or boosted adults KFF.

⭐ By April 2022 through at least August 2022:

Roughly 60% of COVID‑19 deaths were among vaccinated or boosted adults KFF.

This is the most precise, CDC‑based estimate available for the period after vaccines were widely accessible.

🧭 Why did the share of vaccinated deaths rise?

KFF’s analysis (based on CDC data) explains several drivers KFF:

• Most older adults were vaccinated, so the pool of unvaccinated people shrank.
• Waning immunity without boosters increased vulnerability.
• Low booster uptake among high‑risk groups.
• New variants and reduced masking increased exposure.
• Vaccinated people tend to be older, and age remains the strongest risk factor for death.

This does not mean vaccines stopped working — only that the composition of the population changed.

📉 What about 2023–2024?

The CDC stopped publishing detailed vaccination‑status mortality tables in 2023.

However, the pattern from late 2022 likely continued:

• High vaccination rates among older adults
• Waning immunity
• Low booster uptake
• Fewer unvaccinated people remaining

These factors tend to push the share of vaccinated deaths upward even when absolute death rates among vaccinated people remain far lower than among the unvaccinated.

🧠 Bottom line

From late 2021 onward:

• 30% of COVID‑19 deaths were vaccinated (late 2021)
• 40% by January 2022
• ~60% from April–August 2022

All based on CDC data summarized by KFF KFF.
