{"doi":"10.32394/pe.77.08","title":"Implementation of the preventive vaccination program in the time of the COVID-19 pandemic – single center study","abstract":"<p><strong>ABSTRACT</strong><br /><strong>INTRODUCTION.</strong> In addition to many diagnostic and therapeutic procedures, the COVID-19 pandemic also limited prophylaxis, including the implementation of the vaccination program among children.<br /><strong>OBJECTIVE.</strong> The aim of the study was to assess the implementation of the vaccination program in the area covered by the care of patients of a selected Primary Health Care clinic in the city of Krakow in the field of selected vaccinations during the COVID-19 pandemic.<br /><strong>MATERIAL AND METHODS.</strong> A retrospective study based on secondary data was conducted in a selected clinic (Kraków, Poland) that cares for 1,982 children aged 0-19 years. An analysis of the vaccination coverage in selected groups of children in 2019, 2020 and 2021 was carried out based on annual reports (MZ-54). Vaccination coverage against: diphtheria, tetanus, whooping cough, measles, mumps, rubella, influenza and pneumococcal infection was analyzed. The collected data were analyzed using descriptive statistics, Chi2 test and Fisher’s exact test.<br /><strong>RESULTS.</strong> In the general vaccination status of two-year-olds, no significant differences were observed in the period 2019-2021 (p=0.156). The percentage of fully vaccinated increased from 77.6% in 2019, to 81.5% in 2020 and to 85.2% in 2021. However, a high rate of vaccination refusals was observed in 2021 (4.1%) in this group. The percentage of 2-year-olds vaccinated against pneumococci (PCV) and 3-year-olds against diphtheria, tetanus, pertussis (DTP), and measles, mumps, rubella (MMR) in the years 2019-2021 was increasing. For DTP and MMR, this increase was significant (p<0.05). In the group of older children, in 2020 the percentage of 7- and 15-year-olds vaccinated decreased compared to 2019 and 2021, but the difference was insignificant (p>0.05).<br />A significant difference in vaccination coverage was observed in the group of 19-year-olds, in which in 2020 the percentage of vaccinated was 58% (in 2019 – 74.6%, in 2021 – 81%). The largest number of children under the age of 5 were vaccinated against influenza in 2021, but it was only less than 2% of this group.<br /><strong>CONCLUSIONS.</strong> Sanitary restrictions introduced during the COVID-19 pandemic did not significantly affect the vaccination status of children in selected age groups against the analyzed vaccine-preventable diseases. The exception is the group of 19-year-olds, whose vaccination coverage in 2020 was much lower than in 2019 and 2021. In addition, an increase in refusals of vaccination was observed, reaching 4.1% in 2021 in the group of the youngest patients.</p> <p><strong>STRESZCZENIE</strong><br /><strong>WPROWADZENIE.</strong> Poza wieloma procedurami diagnostycznymi i terapeutycznymi, pandemia COVID-19 ograniczyła też profilaktykę, w tym realizację powszechnego Programu Szczepień Ochronnych (PSO) wśród dzieci.<br /><strong>CEL PRACY.</strong> Celem badania była ocena realizacji PSO w grupie pacjentów objętych opieką wybranej przychodni Podstawowej Opieki Zdrowotnej na terenie miasta Krakowa w zakresie wybranych szczepień ochronnych w trakcie pandemii COVID-19.<br /><strong>MATERIAŁ I METODY.</strong> Badanie retrospektywne na podstawie danych wtórnych zostało przeprowadzone w wybranej przychodni (Kraków, Polska), która opiekuje się 1982 dziećmi w wieku 0-19 lat. Przeprowadzono analizę stanu zaszczepienia wybranych grup dzieci w latach: 2019, 2020 oraz 2021 na podstawie raportów rocznych (MZ-54). Przeanalizowano stan zaszczepienia przeciw: błonicy, tężcowi, krztuścowi, odrze, śwince, różyczce, grypie oraz zakażeniu pneumokokami. Zebrane dane analizowano za pomocą statystyk opisowych, testu Chi2 oraz dokładnego testu Fishera.<br /><strong","journal":"Przeglad Epidemiologiczny","year":2023,"id":388338,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.959,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1157563,"name":"Marcelina Potocka","orcid":"0000-0003-2011-530X","position":1,"is_corresponding":false},{"id":1157562,"name":"Marek Wojczyk","orcid":"0000-0002-5104-368X","position":0,"is_corresponding":true}],"reference_count":14,"raw_metadata":null,"created_at":"2026-07-19T01:18:13.977537Z","pmid":"37283302","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
