He has "interpolated" missing data points as lying on the graph between the existing points. But we do have data points, in the raw data. What we see is that, in terms of the "per 100,000" column H if the value of dead was 0,1 or 2 the data was marked as a -. Meaning "to low to meaningfully calculate". If you wanted to graph it the correct value would be ZERO. Not what ever value is between the last two numbers.
The graph is wildly incorrect. (I figured this out doing averages of the two data sets being graphed) Which means that the assertion being made using the graph is also wildly incorrect.

So, for the most recent week reported "under 60" "all deaths", the numbers are: 68 for unvax'd
Then 4 for vax'd within 21 days of 1st dose,
34 for vax'd 21+ days after 1st dose
400 for 2nd dose.
For a total of 68 "all deaths" for unvax'd, and 472 "all deaths" for partial or fully vax'd (with fully vax'd making up vast majority).
