Vaccination
Over the last decade, there has been a disturbing rise in pseudo-science and a rejection of vaccines. The incredible work that went into eradicating diseases such as polio, smallpox and TB seems to have been forgotten.
So, I do like how straight to the point this sign is. As lovely as lollipops are, the main reason for getting a vaccine is so that you don’t get sick and die. That’s a pretty big incentive if you ask me.
