[Impact of vaccination against COVID-19 in children aged 5-11 years: a mathematical model.].

On November 25, 2021, the European Medicines Agency (EMA) authorized the presentation of Comirnaty vaccine (Pfizer-Biontech) for children between 5 and 11 years of age. In our country, this vaccination began on December 15, after it was approved by the Public Health Commission. A mathematical model has been developed to evaluate the possible impact of this vaccination and contribute to assessing the risk-benefit balance.

[Predictions of three mathematical models related with the COVID-19 Vaccination Strategy in Spain. June 2021.].

The Ministry of Health has coordinated three studies that have estimated the impact of the COVID-19 Vaccination Strategy in Spain. The models aim to help how to establish priority population groups for vaccination, in an initial context of dose limitation. With the same epidemiological and vaccine information, the results of this three different mathematical models point in the same direction: combined with physical distancing, staggered vaccination, starting with the high risk groups, would prevent 60% of infections, 42% of hospitalizations and 60% of mortality in the population.
