I assume you mean deaths as it is pretty clear younger people are the main people catching covid, which wasn't the case before vaccination started. If you look at the number of covid cases you can see the effect of vacciniation over time as each age group was able to get their vaccinations. Compare deaths overall with deaths this week you will the age ranges of the people who died has changed radically. Covid like most diseases is more likely to kill people with comordities but in the case of covid more than half the adult population has at least one comordity. How many people don't have asthma or any other lung problem, diabeties, high blood pressure, COPD or are overweight not that many people under 50 i would wager.
