Novel painless flu vaccine methodClinical study and stability assessment of a novel transcutaneous influenza vaccination using a dissolving microneedle patch.
We investigated a new influenza vaccination method using a dissolving microneedle patch made from hyaluronic acid. This painless transcutaneous immunization (TCI) was tested against traditional subcutaneous injections.
In our study, we compared the immune responses between two groups: one receiving the microneedle patch, and another getting standard injections. Both methods showed similarly strong immune responses against the A/H1N1 and A/H3N2 strains.
Notably, the TCI group exhibited a stronger immune response to the B strain. These findings suggest that this new vaccination approach could be an effective and user-friendly alternative to traditional methods.

A class product! This very good supplement, combined with collagen and vitamin C, works wonders. I use it to restore inter-articular fluid. After a week, my knees no longer crunch, and after two to three weeks, my back condition has improved due to an old injury.
