Why are advertisers allowed to claim that the latest COVID-19 shots are more effective?
CVS says “The bivalent vaccine provides added protection against COVID-19 and the Omicron variant”:
Let’s ignore the fact that the customer depicted got COVID a month later. My question is how CVS is allowed to make the claim regarding “added protection” for this emergency use authorized injection. Ordinarily, a company cannot make claims for a medicine without a fair amount of data. But it is way too soon to know if these new shots will reduce hospitalization and/or deaths compared the rate among those who got their 4th or 5th shot with the 2020 version. The tests that have been done look at antibodies in the blood and the effect on someone who is exposed to SARS-CoV-2 is unknown. Shouldn’t CVS be limited to saying “We hope that it will work better…”?
“New Covid Boosters Aren’t Better Than Old Ones, Study Finds” (Bloomberg, October 25):
Bivalent booster shots from Moderna Inc. and Pfizer Inc. failed to raise levels of protective proteins called neutralizing antibodies against the dominant omicron strains any more than four doses of the original Covid vaccine, according to an early independent study on a small group of people.
Researchers at Columbia University and the University of Michigan compared levels of neutralizing antibodies in blood samples from 21 people who got a fourth shot of the Moderna or Pfizer-BioNTech SE bivalent boosters against antibody levels in 19 people who got four shots of the original vaccines.
The results don’t mean that getting a bivalent shot has no benefit, and it will need to be confirmed in much larger studies.
The results also contrast sharply with an Oct. 13 press release from Pfizer and BioNTech touting “positive early data” from a clinical trial suggesting that its bivalent vaccine “is anticipated to provide better protection.” The statement was based on data collected from subjects in the first seven days after immunization, and the company has not yet released details.
I like the highlight text! Our assumption should always be that whatever is new and shiny in pharma will benefit us! (See also Bad Pharma.)

Who here wants to brag about getting his/her/zir/their bivalent booster?
