Results Are Coming “Poor Success with new XBB.1.5 Vaccine”!
Did they Guessed Incorrectly in producing new Vaccines!
By John L. Elliott MS
Yesterday, I was with my son John L Elliott Jr M.D. He shared the new XBB.1.5 Vaccine appears to not be working well as expected on the new SARS-COV-2 cases. I then pulled up several papers talking about the several new methods being researched to increase vaccine effectiveness that show up in my daily feed.
A new Covid variant has become dominant amid slow uptake of the updated shots
The variant, called HV.1, replaced EG.5 as the country’s most prevalent this week, according to data released Friday by the Centers for Disease Control and Prevention.
The two variants are genetically similar versions of omicron.
HV.1 makes up around 25% of Covid cases now, up from around 1% at the beginning of August. EG.5, meanwhile, represents nearly 22% of cases, down from 24% at the start of the month. It appears BA.2.86 is not increasing.
Both are descendants of the XBB variant. The updated Covid vaccines from Pfizer and Moderna, which became available last month, target a different XBB descendant, called XBB.1.5.
But disease experts say the new shots should offer cross-protection against the currently dominant strains. Dr. Scott Roberts, an infectious disease specialist at Yale Medicine, said that although the vaccine is not a “perfect match” for HV.1, “it’s still a good match because it’s still within the same family of variant.”
