Omicron and its sub-variants have become increasingly transmissible (it's what viruses do) and we may end up needing a newer vaccine, but that does not invalidate the hundreds of thousands, if not millions, of lives saved by vaccinations...be very glad you got vaccinated as it will dramatically improve your odds of having a mild case of COVID, should you get infected...and please don't misinform any family members about this, or dissuade any from getting vaccinated if they haven't done so already.
