Mutation is one of the characteristics of SARS-CoV-2. Recently, scientists have identified a new strain of the coronavirus that has become dominant worldwide and appears to be more contagious than the versions that spread in the early days of the COVID-19 pandemic, according to a new study led by scientists at Los Alamos National Laboratory.
The new strain appeared in February in Europe, migrated quickly to the East Coast of the United States and has been the dominant strain across the world since mid-March, the scientists wrote.
In addition to spreading faster, it may make people vulnerable to a second infection after a first bout with the disease, the report warned.

It does totally depend on what and where mutation occur. If these are small SNP type mutations then the overall impact may be minor in its pathophysiology and phenotype and so long as the proteins the vaccine reacts to are not massively different there should still be a positive effect from them. The same is true for the incubation periods
Stephen Reynolds you are right. and Nafees Mohammad Professor, you can follow the link that Ijaz Durrani
had added. Thanks
Yes, the current (March - early April 2021) 3rd wave of the SARS-CoV-2 (Covid-19) coronavirus pandemic is caused by a new variant of the Coronavirus characterized by a higher by approx. 70 percent. contagious than the variants of this virus that caused the 1st and 2nd waves of the pandemic. In the country where I operate at the turn of March and April 2021, the share of a new variant of Coronavirus in terms of new infections of citizens with this virus was estimated at about 80%. with a tendency to continue growing. However, it cannot be completely ruled out that another fourth wave of the pandemic will not occur before the middle of this year 2021. This is possible if recently detected, new, mutated, new variants of the SARS-CoV-2 (Covid-19) Coronavirus, which, for example, have been detected in certain places in South Africa and South America, will spread rapidly on a global scale.

Dear @Nafees Mohammad If there is a "silent or neutral" mutation, it will have no effect on incubation period or virulence of the previous strain. However, if the mutation is of "missense" type, it is likely to drastically change the virulence, incubation or other properties of virus. In such a situation, the efficacy of vaccine is likely to be affected.

Vaccines are producing mutations ...
vaccine developed for one stain may not fully protect a person from infection of different stain of virus
