Yes. Unvaccinated children who contract measles often end up in emergency departments due to severe symptoms such as high fever, rash, vomiting, conjunctivitis, and stomach pain. Some may also experience serious complications like pneumonia or encephalitis (brain infection).
Yo, I'm Tyler, 13 from Exeter. Got the HPV vaccine in school this week. Thought it'd hurt loads, but nah, just a quick poke in the arm. The people there explained everything proper, no rush. Felt a bit sore for a day, but that's it. Now I know I'm protected and helping to protect others from bad things later on. Proper smart move, yeah?
