This will eventually blow over. People getting infected with a variant that the vaccine does not prevent infection against, will still develop their immune reaction for that variant. At some point in the future there will once again be a balance between the collective immune response and the transmissability of the virus. The vaccines available right now are still obviously the best measure we have to make getting to that point less painful, as they reduce hospitalizations dramatically. It's pretty obvious that e.g. if a 50% vaccination rate leaves the ICU at 10x capacity during an unmitigated outbreak, a 90% vaccination rate would be preferable even if it doesn't prevent the need for quarantine measures. This means that contact-reducing measures don't have to be as severe while the outbreak is happening.
