actually it does work somewhat quite well, not perfectly. it s definitely the the mutation is giving it a run for its money. but still it is working. let s look at what s been found by a pfizer study and by a south african study. what they found is that two doses may not provide sufficient protection against infection with omicron. in other words, there is a possibility that you are going to you ll be fully vaccinated and still get infected with omicron. now if it doesn t get you sick, that s not necessarily such a big deal. but they did find the two doses may still give significant protection against severe disease. that s really what we re looking for is that for the vaccine to keep you out of the hospital and out of the morgue, and what they found is that a third dose may give more robust protection. so again, all of this is to say the bottom line is get vaccinated, of course, and when you are six months out from your second shot, get yourself a booster. john? elizabeth cohe
