ChatGPT: — I compiled a country-by-country count of mandatory childhood vaccines in EU/EEA countries using the 2024 rapid review (Vaccines / MDPI) as the primary source and the ECDC Vaccine Scheduler as the underlying reference the paper used. MDPI+1

What I counted and important caveats

• I counted individual vaccine antigens listed in the MDPI paper (the paper’s Table 1 columns):
  diphtheria, tetanus, pertussis, hepatitis B, Hib, poliomyelitis, measles, mumps, rubella, varicella, meningococcal disease, pneumococcal disease (12 possible items).
• Where the MDPI text said a country “has mandatory Tdap (diphtheria, tetanus, pertussis)” I counted that as three mandatory antigens (D + T + P). Malta is explicitly noted in the paper as requiring only diphtheria and tetanus (so counted as 2 for that row). Germany is described as having measles mandatory only (mumps and rubella recommended), so Germany was given 1 for measles.
• These counts are based on the MDPI article’s summary of national schedules as of September 2024. National laws and schedules can change; for definitive up-to-date wording for any country, consult the ECDC Vaccine Scheduler or the country’s official public-health site. MDPI+1

Quick headline

• 13 countries had at least one mandatory pediatric vaccine as of the paper’s review; 17 countries had no mandatory pediatric vaccines (recommendations only). The per-country counts below reflect how many of the 12 antigens above the MDPI review marks as mandatory for that country. MDPI

Mandatory-vaccine counts (EU/EEA countries, per MDPI Table 1 — counts of antigens marked mandatory)

• Austria — 0
• Belgium — 1 (polio)
• Bulgaria — 10
• Croatia — 10
• Cyprus — 0
• Czech Republic — 9
• Denmark — 0
• Estonia — 0
• Finland — 0
• France — 11
• Germany — 1 (measles only)
• Greece — 0
• Hungary — 11
• Iceland — 0
• Ireland — 0
• Italy — 10
• Latvia — 11
• Liechtenstein — 0
• Lithuania — 0
• Luxembourg — 0
• Malta — 3 (diphtheria + tetanus + polio — note: pertussis is not required in Malta per the paper)
• Netherlands — 0
• Norway — 0
• Poland — 10
• Portugal — 0
• Romania — 0
• Slovakia — 10
• Slovenia — 9
• Spain — 0
• Sweden — 0

(These are counts of distinct antigens marked mandatory in the MDPI table; e.g., a country with D,T,P,HepB,Hib,Polio,MMR would be counted as 3 (D/T/P) +1 +1 +1 +3 = 9.)

Short interpretation

• The highest counts (France, Hungary, Latvia → 11) reflect countries that made almost all included pediatric antigens mandatory in the period reviewed. Several countries (Bulgaria, Croatia, Italy, Poland, Slovakia) also show high numbers (around 10). About half of the EU/EEA countries have zero mandatory childhood antigens per the MDPI review — they rely on recommended schedules. MDPI
