Methods: The mumps cases reported to the Czech nationwide surveillance system from 2013 to 2022 were analysed using logistic regression with an odds ratio (aOR) adjusted for age, sex, year of onset and administrative region to measure the association between vaccination and complications or hospitalisation. Adjusted vaccine effectiveness (aVE) was calculated: aVE=(1-aOR)x100. Results: A total of 11,913 mumps cases were reported, of which 6,885 (58%) were male. The median age of the study participants was 16 (range: 0–89 years). No complications occurred in 91% of patients. Mumps orchitis occurred in 633 (9%) male cases. A total of 946 (8%) patients required hospitalisation. The highest proportion of complications and hospitalisations was in the age group 35–44 years. Two doses of vaccine reduced statistically significantly the risk of any complications and of hospitalisation compared with unvaccinated patients: aOR 0.48 (95% CI: 0.37, 0.62), aVE of 52% (95% CI: 38, 63); and aOR 0.43 (95% CI: 0.33, 0.56), aVE of 57% (95% CI: 44, 67), respectively. Two doses showed statistically significant aVE 50% (95% CI: 32, 64) against orchitis, and 59% (95% CI: 23, 79) against meningitis. Among the two-dose recipients, the proportion of complications increased gradually with the time from the second dose. Conclusions: Our findings demonstrated a protective effect of two-dose vaccination against mumps complications and hospitalisation for mumps. We recommend continuing routine childhood mumps vaccination and maintaining high MMR coverage in CzechiaUvod: Analizirali smo podatke o mumpsu, da bi ocenili učinek cepljenja na zaplete in hospitalizacijo zaradi mumpsa. Metode: Primere mumpsa, ki so bili v obdobju 2013–2022 prijavljeni v državni sistem nadzora na Češkem, smo analizirali z logistično regresijo z razmerjem obetov (aOR), prilagojeno glede na starost, spol, leto začetka in upravno regijo, da bi ugotovili povezavo med cepljenjem in zapleti ali hospitalizacijo. Izračunali smo prilagojeno učinkovitost cepiva (aVE): aVE = (1 – aOR) x 100. Rezultati: Skupaj je bilo prijavljenih 11.913 primerov mumpsa, od tega 6885 (58 %) pri moških. Povprečna starost udeležencev v študiji je bila 16 let (razpon: 0–89 let). Pri 91 % bolnikov ni prišlo do zapletov. Mumps orhitis se je pojavil pri 633 (9 %) moških. Skupaj je 946 (8 %) bolnikov potrebovalo hospitalizacijo. Največji delež zapletov in hospitalizacij je bil v starostni skupini 35–44 let. Dva odmerka cepiva sta statistično pomembno zmanjšala tveganje za nastanek morebitnih zapletov in hospitalizacijo v primerjavi z necepljenimi bolniki: aOR 0,48 (95 % IZ: 0,37, 0,62), aVE 52 % (95 % IZ: 38, 63) in aOR 0,43 (95 % IZ: 0,33, 0,56), aVE 57 % (95 % IZ: 44, 67). Dva odmerka sta pokazala statistično pomembno aVE 50 % (95 % IZ: 32, 64) v primerjavi z orhitisom in 59 % (95 % IZ: 23, 79) v primerjavi z meningitisom. Delež zapletov med prejemniki dveh odmerkov se je postopoma povečeval s časom od drugega odmerka. Zaključki: Naše ugotovitve so pokazale zaščitni učinek cepljenja proti zapletom in hospitalizaciji zaradi mumpsa. Priporočamo nadaljevanje rutinskega cepljenja otrok proti mumpsu in ohranjanje visoke stopnje precepljenosti s cepivom OMR na ČeškemTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaNacionalni inštitut za javno zdravje
