Vaccines aren't perfect - you can get vaccinated for certain diseases/strains (such as the flu) and still get them. It's the aggregate of vaccines that stops transmission and prevents disease outbreaks. That's what a lot of people (including other people that replied to my comment) don't understand about vaccinations - they reduce the chance of acquiring a disease. It's still entirely possible to get vaccinated, spend a lot of time around infected people, and get sick. The entire point of herd immunity is to make disease less likely to spread between individuals so that outbreaks don't occur in the first place. Even though the vaccine this year is less effective than normal at preventing the spread of flu, it's still pretty effective, and in a way that means that collectively it's more important to get vaccinated this year.
