Of course it is still a possibility. No one ever said it wasn't. However it is a substantially LOWER possibility than without the vaccines. And the more people that get the vaccines, the lower that possibility chance continues to go. That should be the key takeaway. Unless we can 100% eliminate the virus globally, a "possibility" of something will always exist.
So my point is there will always be a possibility of variants just like the flu each year. Just like the flu vaccine, it does not stop all variants. Covid Sars-2 was used for this vaccine, Covid-19 maybe used for future vaccines. The objective is always to try and keep up.
