Abstract: In this work, we propose a SEIR model with two vaccination doses by a stochastic cellular automaton. For this, we analyse three different scenarios of vaccination: (i) unlimited doses, (ii) limited doses into susceptible individuals, and (iii) limited doses randomly distributed overall individuals. Our results suggest that the number of vaccinations and time to start the vaccination are more relevant than the vaccine efficacy, delay between the first and second doses, and delay between vaccinated groups. Furthermore, scenarios (ii) and (iii) are more realistic and the (ii) is more efficient, once the vaccination is applied to people who have not yet been infected.

State of Paraná

Where the group was born


         Paraná is one of the 26 states of Brazil, located in the south of the country, bordered on the north by São Paulo state, on the east by the Atlantic Ocean, on the south by Santa Catarina state and the province of MisionesArgentina, and on the west by Mato Grosso do Sul and Paraguay, with the Paraná River as its western boundary line.

    It is subdivided into 399 municipalities. Its capital is the city of Curitiba. Other major cities are LondrinaMaringáPonta GrossaCascavelSão José dos Pinhais and Foz do Iguaçu. Crossed by the Tropic of Capricorn, Paraná has what is left of the Araucaria forest, one of the most important subtropical forests in the world. At the border with Argentina is the National Park of Iguaçu, considered by UNESCO as a World Heritage site. At only 40 km (25 mi) from there, at the border with Paraguay, the largest dam in the world was built, the Hidroelétrica de Itaipu (Itaipu Hydroelectric Dam). The crime rate is considered low by Brazilian standards and the state is one of the most developed in the nation.
