Its obvious, but this will explain it to you.
{...
Historically, the most effective vaccines have used
replicating viruses, which essentially elicit lifelong immunity.
Measles and chickenpox vaccines use replicating viruses.
...
The Pfizer and Moderna messenger RNA COVID-19 vaccines,
which work differently, don’t contain any virus at all.

{...
Most often, vaccines put a weakened or inactivated germ into our bodies, leading our immune system to create antibodies that will protect us from the virus if we’re ever infected in the future. The mRNA vaccines available right now (Pfizer and Moderna) do not contain any virus. Instead, these vaccines teach our cells how to make a protein that prompts our immune system to produce antibodies.
...
In the case of COVID-19, mRNA vaccines, when injected, give instructions to our cells to make the “spike protein.” The spike protein is a harmless piece of the virus, and in this case it’s found on the surface of the virus that causes COVID-19. When the vaccine is injected, the instructions then tell the cells to make a protein piece. These proteins can’t hurt us; they aren’t part of a replicating and exploding virus that destroys our cells and makes us sick. But the proteins are enough to trick our immune system into building up antibodies to protect us.

See the difference?
No long term protection with mRNA.
Its not a vaccine.
Its only a treatment.
