It looks like vaccines should be useful for longevity because they prevent serious illnesses caused by viruses, but also because many other conditions often associated with age seem to be triggered by viral infections
For instance, see:
i) Longitudinal analysis reveals high prevalence of Epstein-Barr virus associated with multiple sclerosis
ii) Possible Connection Between Herpes Group of Viruses and Various Conditions that Arise with Age
iii) Lower Risk for Dementia Following Adult Tetanus, Diphtheria, and Pertussis (Tdap) Vaccination
The question I had is what are the vaccines that are currently available for adults to take? Do you know where I can find this information?
Type 1 diabetes can also be triggered by viruses, although which ones is still open for debate. Enterovirus vaccines could go a long way in alleviating the increasing incidence of the disease. Those with the disease have 10-15 year decreased life spans, on average.
In addition, NK cells
undergo expansion during virus infections, such
as those with mCMV (31), influenza A (57), or
vaccinia virus (58). Studies of CMV infection have
shown that NK cell activation may provide T
cell–independent protection against reinfection
by rapidly degranulating and producing cyto-
Once the immune system is activated in younger individuals by SARS-CoV-2 infection, they look younger by the epigenetic clock due to a robust activation of the immune response that reflects in younger individuals (not that they are actually becoming younger).
Complementary longitudinal epigenetic clock analyses of 36 participants prior to and following Pfizer and Moderna mRNA-based COVID-19 vaccination revealed that vaccination significantly reduced principal component-based Horvath epigenetic clock estimates in people over 50 by an average of 3.91 years for those who received Moderna. This reduction in epigenetic clock estimates was significantly related to chronological age and immune cell-type compositional changes in B cells and plasmablasts pre- and post-vaccination. These findings suggest the potential utility of epigenetic clocks as a biomarker of COVID-19 vaccine responses. Future research will need to unravel the significance and durability of short-term changes in epigenetic age related to COVID-19 exposure and mRNA vaccination.
