Yes they did. They have stated that if a variant learns to avoid the current vaccines its a simple thing to adjust them and there would be no need for a further 18 month plus trial and development. It's what they do with the flu vaccine every year.

Warning: I do use the word 'simple' as a relative description of the process compared to making the original simple for brilliant medical scientists that is.
