Will the covid-19 vaccine work forever, or will we need to keep developing new vaccines and continue to get inoculated just like we do for the flu?

We are all still learning about COVID vaccines. Although we now know that it may protect us for 6 months thus booster doses are recommended . Mix and match is now approved .'It seems like it’s heading that way like the yearly flu vaccine.Get vaccinated if you haven’t done so. You don’t want to become a long hauler like others who now regret not getting COVID vaccine sooner.

Not fully clear regarding vaccine duration of protection, but it is now believed that the COVID-19 vaccination program will be done yearly like flu vaccine. The "booster" program is indicative of the need to constantly stay on top of this. Perhaps new vaccines will help, but viral mutations require shifts in prevention.
