This looks like it applies to the original vaccine, not the updated booster anyway - so it seems like an irrelevant paper.
There is a concept in immunology called "Original antigenic Sin", which means that a vaccine (or natural immune response) of an old variant of a virus might hinder your body's ability to generate a more tailored immune response to the current variant.
...but since updated vaccines are now available - you should get that.
