Not\u00edcias sobre as vacinas contra o coronav\u00edrus tomaram conta dos jornais nos \u00faltimos meses. Junto dessas not\u00edcias vieram tamb\u00e9m muitos testes estat\u00edsticos e termos t\u00e9cnicos da \u00e1rea para comprovar a efic\u00e1cia das vacinas. Mas voc\u00ea j\u00e1 conhecia esses termos? Tem ideia de como foi calculada a efic\u00e1cia? <\/p>\n\n\n\n

No artigo de hoje vamos explicar um pouco mais sobre a estat\u00edstica por tr\u00e1s da aprova\u00e7\u00e3o das vacinas. Continue lendo para saber mais sobre essa \u00e1rea da ci\u00eancia respons\u00e1vel por salvar vidas. <\/p>\n\n\n\n

H\u00e1 algumas semanas, a Anvisa deu uma das not\u00edcias mais aguardadas dos \u00faltimos meses. \u201cA Ger\u00eancia-Geral de Medicamentos recomenda a aprova\u00e7\u00e3o do uso emergencial da vacina Coronavac, condicionada ao monitoramento das incertezas e reavalia\u00e7\u00e3o peri\u00f3dica.\u201d<\/p>\n\n\n\n

Mais de 10 meses depois do in\u00edcio da pandemia de coronav\u00edrus, essa not\u00edcia foi muito animadora. E s\u00f3 foi poss\u00edvel pelo esfor\u00e7o de muitas pessoas entre cientistas, profissionais da sa\u00fade e estat\u00edsticos tamb\u00e9m!<\/p>\n\n\n\n

Assim como em v\u00e1rias outras \u00e1reas do conhecimento, na \u00e1rea da sa\u00fade \u00e9 preciso realizar experimentos, coletar dados e analisar quais os impactos de diferentes tratamentos no bem-estar dos pacientes. Com a vacina para o coronav\u00edrus n\u00e3o poderia ser diferente. E, para concluir se um imunizante \u00e9 eficaz, \u00e9 preciso realizar an\u00e1lise de dados com alguns m\u00e9todos estat\u00edsticos.<\/p>\n\n\n\n

Como se calcula a efic\u00e1cia de uma vacina?<\/h2>\n\n\n\n

O processo de cria\u00e7\u00e3o de uma vacina come\u00e7a com a defini\u00e7\u00e3o da melhor composi\u00e7\u00e3o para o imunizante. Essa etapa \u00e9 realizada com experimenta\u00e7\u00e3o in vitro que depois \u00e9 testada em animais para comprovar os dados colhidos no laborat\u00f3rio. O teste em animais checa a seguran\u00e7a e a pot\u00eancia imunol\u00f3gica da vacina. Essa fase \u00e9 conhecida como pr\u00e9-cl\u00ednica. <\/p>\n\n\n\n

Em seguida passamos para a fase cl\u00ednica onde come\u00e7am os testes em humanos. Essa fase \u00e9 dividia em 4 partes: <\/p>\n\n\n\n
