A primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak

<h3>What is antigenic drift?</h3>

Antigenic drift is a phenomenon that causes small changes or mutations in the genes of influenza viruses leading to changes in their surface proteins of the virus, which are HA (hemagglutinin) and NA (neuraminidase).

For this reason, new influenza vaccines are produced yearly to alter the effects that may emerge as a result.

Thus, a primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak

Which of the following events occur at the start of diastolic production of first heart sounds S1
suter [353]

Answer: Ok Diastole commences with the closure of the aortic and pulmonary valves. Intraventricular pressure falls but there is very little increase in ventricular volume (isovolumetric relaxation). Once ventricular pressure falls below atrial pressure, the mitral and tricuspid valves open and ventricular filling begins.The first heart sound (S1) is produced by vibrations generated by closure of the mitral (M1) and tricuspid valves (T1). It corresponds to the end of diastole and beginning of ventricular systole and precedes the upstroke of carotid pulsation.

Hope this helps have a awesome day/night❤️✨
