IT’S BACK:  New COVID-19 Subvariant XBB Is Part of a ‘New Class’ of Omicron

Forewarned, forearmed; to be prepared is half the victory. – Miguel de Cervantes

There’s a new kid on the block of COVID subvariants that’s on the rise and one i called XBB—or Gryphon—is getting a lot of attention and there’s a chance it could overtake everything else out there.


XBB is one of the “new class” of Omicron variants that are spreading fast right now, says Thomas Russo, M.D., professor and chief of infectious disease at the University at Buffalo in New York. That includes BQ.1.1, BQ.1, BQ.1.3, BA.2.3.20, and XBB.
“XBB is a hybrid version of two strains of the BA.2 form of Omicron,” explains Amesh A. Adalja, M.D., a senior scholar at the Johns Hopkins Center for Health Security. It’s currently “spreading efficiently in Singapore,” he adds.
The variant was first detected in August 2022 in India, and has been detected in more than 17 countries since then, including Australia, Bangladesh, Denmark, India, Japan and the U.S., per Singapore’s Ministry of Health.

XBB is thought to be able to evade antibody protections of these newly emerged COVID variants, according to a pre-print study from researchers in China. That study said that the new strains of Omicron, and XBB in particular, “are the most antibody-evasive strain tested, far exceeding BA.5 and approaching SARS-CoV-1 level.

“These variants are evolving to evade protection,” Dr. Russo says. The bivalent booster is “likely going to be protective against severe disease” with XBB, but will be “imperfect against preventing infection,” Dr. Russo says. “Even with immune-evasive variants, vaccine protection against what matters most—severe disease—remains intact.

It’s not over and probably won’t be for a very long time.

  1. I got covid pneumonia the end of July 2021. I was on a ventilator for 17 days. Feeding tube. Dr.s tried to take me off the vent twice and to no avail had to keep me on. My lungs and kidneys were effected. I couldn’t swallow and had many tests. After one month in the hospital I was transported to a physical therapy rehab where I stayed for 3 1/2 weeks. I came home with oxygen and a walker. I did 9 more months of physical and occupation therapy. Losing my balance. I fell and broke my wrist. I have long haulers and more symptoms we just keep adding to the list. I have alot of problems with dehydrating and my kidneys. I’m on a cpap machine at Night to force the air into my lungs and open up my esophagus. I have complications from drop foot from being on the ventilator for so long and my feet in boots. I have hoarse voice and so many other things going on. By the grace of God and my drs.and brother I am here. I’m working part time but will never know life as I knew it before.

    1. My thoughts on this depend upon what you mean. We follow research and the experts. Anybody who doesn’t do this isn’t following society’s expectations of normal upbringing.

  2. I got the vax. Didn’t for my two sons. My oldest son and I got covid. I’m sick as a dog! He’s all better after 3 days?!

    1. Jessica, your son is much younger and has a much stronger immune system than you!! It’s been a consistent and reliable data point that the older and immune-compromised ( And certain pediatric!) who have been the most at risk for severe COVID infections with higher fatality rates ever since 2020 when the SARS COVID virus became zoonotic and started to further mutate!!

      At 72, I will gladly get whatever booster shot or new strain or variant vaccination is offered!! I’ve had 2 breakthrough COVID infections over the past 2 years and now suffer long term COVID’s effects as well!!
      I will do anything to avoid another infection as I’m at risk from multiple causes and I still wear a mask whenever I’m in a public indoor space or in close contact with anyone I’m unsure of as my last breakthrough COVID infection was probably from someone who claimed to be vaccinated and yet, two weeks later, I was ill again!!!
      I still remember the initial polio vaccines when there was no choice.
      I am absolutely infuriated and utterly dismayed at the lack of public health knowledge, its objective presentation and education, and the concurrent blithe non-observance of all scientific evidence by both this nation’s citizenry and its elected representatives of the relevant science who would rather cater to economic interests and their own personal political interests than the public weal!!!

      1. Thank you for your insight. You are so on point that many of these folks in our nation that are younger never faced diseases like polio and are clueless and careless concerning public health. I’m only in my early 50’s and remember the words my grandmother said about vaccines and living with diseases like polio and how grateful she was once vaccines became available. These nut never faced what you and others gave, if they did, they’d change their tune.

  3. Thank you for all the information my son is so afraid going outside he’s 47yrs old and a downs syndrome hè has an infection and now I’m taking him back to his ph to have him tested for covid he has heart problems, and seizures not taking no chances I had two neices passed cousins, and friends that has gone from this devastating thing I’m a 27 cancer survival and I’m taking every thing for protection. Keeping everyone in prayers couldn’t go no where out my family wouldn’t let me go nowhere I lately start going back to church the end of last year we all need to obey God guidance through prayers we can make it.

  4. People!! Pull your heads out o your a___s!! Is there not a new election coming up?? All of a sudden a new strain of vid comes out? COVID IS REAL. I have had it 2x, that I know of, & do suffer from long vid. They are now saying masks did little to hinder the spread of the virus. Hmm…I wonder who, of the powers that be, had more than a few shares in the manufactureing plants that make those masks? Some got very rich ofF this virus & like a buncha village idiot puppets went right along & did what we were told…or else? Untill we lost our businesses, jobs, way of life for a lot of people. Come on!!! Lets all get packed in a grocery store after work cuz its now closing at 8:00 instead of midnight cuz of covid? Makes more sense to stay open more hours to keep us spread apart through out the hours. Or lets all get packed in an airport or on a plane & told we can only remove our masks to eat…or else? Wtf? Yall fell for this crap hook line & sinker till it sunk us!! Open your eyes, quit walking thru life blind deaf n dumb. There is a huge alterior motive(s) behind this covid crap. Omicron variant? The word itself sounds robotic, as in not biological. Think about it. NONE…OF IT MAKES SENSE!!

  5. Al this COVID and all the varieties of it are all government made shit. Learn some truth ppl open your mindd and stop listening to the ppl that are making all the money on the vaccines and meds to treat all the problems associated with COVID. They could cure us if I have money u can cure aids and cancer they have the cures but money talks and you can’t just be the average Joe to get these cures but it’s sick how the pharm companys make money off meds that keep us alive instead of curing is when the cures out there. Look at majic Johnson he ain’t sick no more…so many more famous celebrities and rich people beat all kinds of disease that normal ppl get put on meds to keep us going for a little longer so they can get paid from our insurance and our taxes and every other way they rob is.
