Article Main Content

Background: in the 47 European countries the vaccination against COVID-19 started between December 2020 and January 2021. However, the first wave (W1) was controlled without any vaccine administration

Objective: to analyze the effect of vaccines on COVID-19 deaths rates, comparing the W1 with last wave (W2)

Methods: deaths rates from March 2, 2020, up to May 10, 2021, were recorded from WHO dashboard

The same was for the vaccine doses administered up to the May 9-11, 2021.

The trends of the deaths during W1 were followed for 5 weeks after the peak (6 values), while for the W2 the last 6 weeks from April 5 to May 10, 2021 were considered.

Results: the vaccination coverage was between <2×103 inhabitants (Armenia) and 831 x 103 (UK) and the average was 395×103 inhabitants. Although some differences among countries in the coverage, it seems that vaccination is significantly accelerating the deaths decay which was correlated with the doses administered.

Conclusions: in Europe the decay of deaths due to Covid-19 during the 2020 (W1) was achieved without any vaccination program. However, the vaccine is significantly decreasing the deaths rate proportionally to the amount of doses administered.

Keywords: COVID-19; Vaccines; European Countries.
