Will we have to have the Covid vaccine every year like the Flu jab?

It's too soon to tell, but personally I doubt it.
The virus itself is called SARS-CoV-2. Actually there have already been two forms of SARS: the original SARS and MERS. Both of these have died out on their own, without a vaccine.
Now, SARS-CoV-2 is different in some ways, one being that it is highly contagious. But there is a good possibility that it will not mutate or recombine as much as Influenza.
But we won't know until we know. If covid does change frequently like the flu does, the yearly vaccine will be much easier to create than the first one. The first is the hardest.

We don't know yet.

We don't know... which is a problem with the current potential vaccines.
The IgG and IgM antibodies disappear over time. If immunity is based on these, the immunity is likely short lived.
However, every covid patient has changes to their T-cells. If long term immunity is based on the T-Cells, then immunity may be long term or permanent.
In response to First Dragon -
SARS-CoV-2, MERS, & SARS share about 70% of the same genetic make-up. They are not the same disease.
We eradicated people with SARS. The contagion period was short and the illness was severe, so people were quickly hospitalized / quarantined. Since this stopped community spread, the virus killed itself out (because it was unable to duplicate with people).
MERS still exists.
SARS-CoV-2 which has the common name of Covid-19 is NOT highly contagious. The issue is that it has a long incubation period and for most people relatively minor symptoms. Thus, when people are contagious, they don't remove themselves from the community creating a situation where the virus can spread more easily.

This was asked in the U.K. today. The Doctors think not as it produces antibodies. Too early to say. The flu jab changes each year as flu has different viruses. Covid stays the same.

Yes. In time, there will be a single vaccine for both.

There may be new strains of the virus every year.

It's not impossible. For one thing, we know that the antibodies fade, so unless we're getting vaccines that don't depend, or not entirely, on producing antibodies, we may need vaccines each year.
