This chart says it all. If u got double vaccinated early on & are not yet boosted, ur effectively unvaccinated against Omicron infection. Thus, many adults & teens are effectively unvaccinated against infection. Kids got vaccinated recently & thus may be in a safer position. 1/

2/ This chart speaks to infection, not hospitalization. Thus, those who were double vaxxed early on (but are not yet boosted) may still have some protection against hospitalization—just not against infection, & it’s unclear how much that protection against hospitalization is.
3/ The takeaway should be to get your booster if you qualify (eg, based on when you got your last shot). Also, wear N95s or KN95s. I wish my kids’ middle & high schools had required at least KN95s. Rumor is that a third of the high school is out w/ positive Covid.
4/ Notably, staff seem to be okay. They were required to wear N95s (but students could ware any ole mask). It will be interesting to see if this holds.
5/ PS. As indicated in the chart, even with a booster, vaccines are less effective against Omicron than against Delta. This makes N95 or KN95 masks that much more important.
