The naturally aquired herd immunity theory is often debunked with the rational that immunity towards COVID19 might not be long lasting and therefore herd immunity will be difficult if not impossible to achieve.
It seems like for many a vaccine is the only solution. However if it's true that immunity toward the noval coronavirus lasts only around six months or so, how will a vaccine be helpful?

We don't know yet.

Presumably, if immunity wears off after a year, the recommendation would include annual boosters.

It could be like the flu vaccine which is tweaked every year but since the underlying science and production lines are set up, it's relatively easy to produce an annual flu vaccine which is generally pretty effective.

mRNA vaccines are being developed with the goal to program your genes to respond upon exposure. I personally think this is terrifying.

I’m assuming similarly to the flu vaccine.
That it’s highly effective for most people and it lowers the intensity of the flu if you do still get flu with it.
It’ll help with the medical overflow and will make it that much less Of a massive worldwide issue.

Either similar to the flu vaccine, or very possibly if we get enough people (on a global scale, and on a local scale) vaccinated, we simply stop the virus in its tracks and it disappears completely.

I think by the time a vaccine is available, we'll know more about how long immunity lasts.

I think this is based on a wrong assumption of what mrna based vaccine is

Not likely if it's short acting. Impossible to vaccinate billions of people within such a short amount of time to totally eradicate the virus

I think you may have confused mRNA and DNA vaccines. The latter has the risk of modifying genes, the former does not. Neither is currently approved for use in humans. Both sorts of vaccines (as well as other approaches such as modified adenoviruses, inactivated viruses, and viral proteins) are currently in various stages of testing.

So basically it looks like we're looking at a new seasonal illness who's affects may be mitigated somewhat by an annual vaccine. No magic bullet there.
Now can my kids go back to school please??!!

That depends on a lot of things - how many months we have, how the vaccine is distributed, etc.

We'll see - by the time we managed a vaccine for swine flu, it wasn't relevant anymore. Could be the same this time, too.

As far as I know the only diseases eradicated by vaccines are those like smallpox which give immunity for decades.

How in the world do you think the flu vaccine is very effective? The cdc and makers of the vaccine find it is not very effective. Some year had an only 10% success rate. It has never had as much as a 50% chance any year. Compared to childhood disease vaccines whose success rates are all between 90-100%. Now mix that with corona transmission rates. This vaccine is not looking like a savior. I dont think I would bet on it being one. We need a plan without a savior vaccine.

I just read that the MMR vaccine may give some degree of protection against COVID 19.

I spoke with my doctor regarding the vaccine. Covid is a virus, just like influenza. So is measles, for that matter. The difference is that the measles virus does not mutate. Once the body is protected through a vaccine, it is long term. Influenza, however, mutates constantly and therefore a new vaccine is required each year. Covid is also mutating. For that reason, a yearly vaccine will be required.

If your doctor thinks COVID is mutating at anywhere near the pace of the flu then he needs to read more

I recently learned that the measles virus does mutate. But the important part of it, the one our immune system targets, stays the same, and that's why catching measles or getting vaccinated provides long-term immunity from the illness despite mutations.
