Ok, let's explore the first article.
So they haven't actually repaired any fibrosis in an actual human patient using this method yet, got ya!
Ok, the 2nd article
lol
so none of these are actually being used currently in the repair of myocardial fibrosis? Wow, so helpful.
I guess we'll find out just how mild myocardial fibrosis is, won't we!
The booster (third immunization) dose at 6 to 10 months increased the half-life of the serum–neutralizing antibody (nAb) titers to 76 days from 56 to 66 days after the primary 2-dose vaccination. A second booster dose (fourth immunization) a year after the primary vaccination further increased the half-life to 88 days. However, despite this modestly improved durability in nAb responses against the ancestral (WA.1) strain, there was a loss of neutralization capacity against the Omicron subvariants BA.2.75.2, BQ.1.1, and XBB.1.5 (48-, 71-, and 66-fold drop in titers, respectively, relative to the WA.1 strain). Although only 45% to 65% of participants demonstrated a detectable nAb titer against the newer variants after the booster (third dose), the response declined to below the detection limit in almost all individuals by 6 months. In contrast, booster vaccination induced antigen-specific memory B and T cells that persisted for at least 6 months.
The durability of serum antibody responses improves only marginally following booster immunizations with the Pfizer-BioNTech or Moderna mRNA vaccines.
Maintaining durable immunity following vaccination represents a major challenge, but whether mRNA booster vaccination improves durability is unknown. We measured antibody responses in 55 healthy adults, who received a booster dose of the ...

does that apply to all vaccines or just mRNA vaccines?
