Is influenza an infectious disease?

Influenza or also called the common flu is a viral infection that is transmitted through droplets that may be carried through the air, for example, sneezing, coughing from an infected person to another one. Can also be transmitted from contaminated surfaces. So hand washing is important and wearing face masks that will not allow the droplets from an infected person to be spread from sneezing and coughing.
For this year's circulating influenza strains, the vaccine is not fully protective against one of the strains of influenza covered by the vaccine and we are seeing more cases despite vaccination. This is not uncommon specifically for the influenza vaccine that is developed for each annual season with some uncertainty about the major strains of influenza that will circulate in the future.

Yes it is an infectious disease. However it is typically not spread from one person to another.
In most cases, the malaria parasite has to first pass from a human host into a mosquito as the mosquito takes a blood meal, and then from the mosquito into another human via the mosquito’s saliva. This severely limits the amount of person-to-person transmission that exists. In fact, the only mechanisms for direct transmission between humans are when malaria parasites are passed between a mother and her unborn child via the placenta (congenital transmission) and through unscreened blood transfusions.

Is chicken pox really something you need a vaccine for?

This would prevent many vaccinated children to get a full blown infection and avoids many severe infections which may also leave skin scars. 2nd it prevents the spread of the infection to other unvaccinated or not protected children because the vaccinated children won't carry the disease even before it becomes symptomatic and spread it.
