Semi correct. Yes get your booster (2nd booster - but in September.

The current vaccine and prior covid infection are poorly protective against current predominate circulating strain.
There is an updated vaccine that will available in September (perhaps early October) that should be protective.

As for the numbers shown, 67% of deaths are vaccinated suggests that the majority of people now dying from covid are vaccinated implying that you are more likely to die from covid if you are vaccinated. But 67% of the population is vaccinated and/or boosted so essentially, no difference. However if you do a deeper dive into the numbers presented vaccinated and boosted are less likely to die from covid. Unvaccinated is essentially exactly the percentage. And vaccinated but not boosted are more likely to die.

This can be explained as follows:
1st - vaccinated and boosted is not broken down to vaccinated and boosted once vs vaccinated and doubly boosted.
I would bet if you looked at those numbers the doubly boosted would have even fewer deaths and the vaccinated and boosted would be equivalent ot the vaccinated not boosted.

2nd - Almost everyone vaccinated shortly after the vaccine came out and not boosted will not still have protective levels of antibodies. Depending on when someone got boosted, they may or may not have good levels. However, many of them are going to presume that they still have protective antibodies at adequate levels so will act as if they are protected and actually increasing their risk of getting covid.
