Vaccines are far from being a given like we don’t have a vaccine against common colds, HIV and even Influenza vaccines are seasonal.
They are very certain that there will be an effective vaccine, just not when/what it will look like yet. We have no vaccine for colds, because we don't need one. Colds do not cause severe illness or have any risk of death. HIV is a completely different ballgame. Influenza vaccines are seasonal because they are so widespread, they mutate rapidly, thus make it necessary for seasonal vaccines based on what strains they think are circulating. So far, Covid while it has mutated, hasn't been shown to mutate as rapidly as influenza. But yes, there's a chance Covid might need to be a seasonal vaccine. Oh well - that would still be better than no vaccine. And, as we're now learning, many vaccines wear off over time and have to be rea-dministered - Measles, Pertussis, Tetanus etc... so it's not that big of a deal, really.
