Kids are given winter vaccines to reduce spread to elders to keep hospital admissions down. No other big benefit. Catching a mostly harmless flu one year builds natural immunity but yearly vaccines can weaken natural immunity. Another reason we have kids vaccinated for winter viruses is because parents can no longer afford/allowed time off work to look after poorly (flu/covid) children to prevent the spread themselves. Even schools want kids in while poorly! Make it make sense 🤷‍♀️
