ARNIs help treat heart failure by keeping the blood vessels from constricting. This can lower blood pressure and make it easier for the heart to pump blood throughout the body, easing the strain on the heart.
ARNIs contain a medication called
Sacubitril blocks
sacubitril.
— an enzyme that
neprilysin
peptides that clear the body of excess sodium and fluid, which can both contribute to high blood pressure.
interferes with the natriuretic
By blocking neprilysin, the natriuretic peptides are able to flush the sodium and fluid out of your body, lowering your blood pressure.
ARNIs also contain the drug
valsartan.
angiotensin
By preventing
from causing blood vessels to narrow, it also lowers
blood pressure.

They contain altered influenza viruses that are either:
attenuated (weakened)
inactivated (killed)
fragmented
That way, when they’re injected into your body, they won’t make you sick.
But your immune system will see a threat and send different types of white blood cells to destroy the altered virus.
Certain immune system cells — B cells and killer T cells — will remember what the virus looks like.
B cells will also produce antibodies that specifically target the flu virus.

Dendritic cell
Killer T cell
So, if the real virus gets into your body, the immune system will recognize it and destroy it.

Flu vaccines teach the immune system to recognize the influenza virus and produce antibodies tailor-made to destroy it.
