Maybe but then again, the vaccines went from published SARS-CoV-2 genome to vaccine approval in less than a year too. A booster shot under those circumstances seems pretty consistent under that compressed timeframe. 10 years from now people will probably get something more stable with boosters at bigger intervals. A vaccine is a vaccines; just because the virus is evolving quickly doesn't mean it's not. You're still almost certainly way better off with a vaccine than not.
