Analysis of Data Published in the Internet by the Ministry of Health of Northern Ireland on Covid-19 Vaccinations, Hospitalisations and Deaths for the Period 30th August to 19th December 2021

Analysis of data from the Department of Health of Northern Ireland for the period 30th August to 19th December 2021 showed significant beneficial effects of COVID-19 vaccination in reducing the percentages of COVID-19 cases admitted to hospital and COVID-19 deaths in all age cohorts of the population. In the studied period Northern Ireland had a very high percentage of population fully vaccinated against COVID-19, 77% of the population below 50 and 93% of the population over 50 years of age. As an example of the beneficial effects of vaccination, in the “60-69” age cohort the percentage hospitalised with COVID-19 was 2.40% for not vaccinated and only 0.18% for the fully vaccinated. The percentage deaths from COVID-19 for the “60-69” not vaccinated population were 0.28%, for the fully vaccinated 0.03%. Unexpectedly, the percentages of deaths from COVID-19 cases admitted to hospital were lower for not vaccinated patients in the age cohorts “18-49”, “50-59”, “60-69”, “50 and over” and “all adults”, compared to the fully vaccinated in the same age cohort: “18-49”, 2.1% deaths “not vaccinated”, 4.3% deaths “fully vaccinated”; “50-59”, 5.8% deaths “not vaccinated”, 8.1% deaths “fully vaccinated”; “60-69”, 11.9% deaths “not vaccinated”, 16.5% deaths “fully vaccinated “ and “50 and over”, 17.8% deaths “not vaccinated”, 21.7% deaths “fully vaccinated”. The difference was the highest for the “all adults” cohort: 10.5% deaths in the not vaccinated COVID-19 hospitalized patients and 20.2% deaths in the fully vaccinated group
