Probably because going through another round of certification is harder than using the existing vaccine as a booster, the hope being that this will already significantly improve delta resistance.
Why not both?

Does anyone know why they haven't released a Delta varient vaccine? Is seems that it would just involved we changing the mRNA sequence in a computer at the factor, but I'm really just guessing. Also maybe it is considered a whole new vaccineand needs to go through approval again.
There's nothing to update. The mRNA allegedly encodes for the 'spike' protein, which is the infection vector. The theory at the time was that by targeting that protein specifically, if the virus were to mutate, it would loses it's ability to infect because it could no longer successfully bind to the ACE2 receptors. In practice, the efficacy is a fraction of what the trials stated it was. It didn't lose efficacy due t…

It's nothing compared to the other tick disease: tick borne encephalitis. Thankfully there's a vaccine against that
Though it's not available in the US.

What makes them not vaccines?
A desire to avoid being called anti-vax.
Prepare to read the headline "mRNA vaccine trial for " a lot in the future. My guess is that they are going to produce mRNA versions of basically any vaccine (and then some) in the future. The nice thing about the technology seems to be that you only need to exchange the mRNA payload while the surrounding delivery method can be reused. That makes it not only a fast method to create a vaccine but a very convenient way…

IIRC these trials should last 3 months

Safety and speed must usually be balanced in a trade-off, and we are actually used to it, that is why people drive a car, even though it comes with a risk of dying or being maimed. I have no doubt that some kind of safety-related trials must be run on boosters and that they will be run, but they will likely only take weeks in the future, not months.
> but they will likely only take weeks in the future, not months. We need just one Jesse Gelsinger to shut the whole thing down.
We now have a few hundred million people who got mRNA vaccine and had no trouble. I don't think that even after a death, mRNA would be completely toast. It has already proven its merit.

The disease appears to be a problem mainly in Europe and Asia, but if you're planning a camping trip in those areas it looks like you can ask a doctor for the vaccine. You also can get the disease from unpasteurized dairy products.
