Frequently Asked Questions
Why do infants need so many vaccines at once?
Multiple vaccines at the same visit protect against diseases as early as possible. Research shows infant immune systems handle many antigens simultaneously — the combined exposure from vaccines is far less than what a child encounters naturally each day.
What is the recommended childhood vaccine schedule?
The CDC/ACIP schedule covers: Hepatitis B (birth, 2, 6 months), DTaP (2, 4, 6, 15–18 months, 4–6 years), Polio, Hib, PCV, MMR (12–15 months, 4–6 years), Varicella, and more. Check the current official schedule as it is updated annually.
Are vaccine schedules the same in all countries?
No. Each country's national health authority develops its own schedule based on local disease burden, vaccine availability, and population health priorities. The WHO provides guidance but individual schedules vary.
