Rising measles cases globally threaten children's immunity, reversing gains from vaccinations.

Measles cases are rising globally, threatening children's immune systems by causing "immune amnesia," which can make them vulnerable to other diseases. Despite the measles vaccine preventing over 60 million deaths since 2000, declining vaccination rates due to hesitancy and misinformation have led to outbreaks in several countries, including the UK and Ireland. The vaccine not only protects against measles but may also offer broader immune benefits, making it crucial for protecting children from multiple diseases.
