Nas fases 2 e 3, ser\u00e3o vacinadas 4 mil mulheres entre a\u00a024\u00aa e a 34\u00aa semana de gesta\u00e7\u00e3o\u00a0<\/strong>para avaliar a seguran\u00e7a, tolerabilidade e imunogenicidade de duas doses de BNT162b2 ou placebo, administradas com\u00a021 dias de intervalo<\/strong>. Cada uma delas participar\u00e1 do estudo por aproximadamente 7 a 10 meses, a depender do tipo de produto que ela recebeu (placebo ou vacina). O estudo tamb\u00e9m vai avaliar o potencial de transfer\u00eancia de anticorpos que a m\u00e3e pode passar ao beb\u00ea.<\/p>\n

As crian\u00e7as ser\u00e3o monitoradas at\u00e9 cerca de 6 meses de vida<\/strong>. Conforme estabelecido no protocolo, ap\u00f3s o nascimento, ser\u00e1 revelado se a m\u00e3e fazia parte do grupo do placebo. Em seguida, ela ser\u00e1 vacinada.<\/p>\n

Antes de realizar o ensaio cl\u00ednico da vacina contra a covid-19 em gr\u00e1vidas, a Pfizer e a BioNTech conclu\u00edram um estudo de toxicidade reprodutiva e de desenvolvimento (DART) com o imunizante, que foi exigido pelas autoridades regulat\u00f3rias antes de iniciar o estudo em mulheres gr\u00e1vidas.\u00a0Esses estudos n\u00e3o mostraram evid\u00eancia de fertilidade ou toxicidade reprodutiva em animais<\/strong>.<\/p>\n

Crian\u00e7as<\/h3>\n

As empresas esperam come\u00e7ar a testar a vacina em crian\u00e7as entre 5 e 11 anos nos pr\u00f3ximos meses. J\u00e1 em crian\u00e7as abaixo de 5 anos, a expectativa \u00e9 que os testes comecem no fim de 2021.<\/p>\n

A seguran\u00e7a e efic\u00e1cia entre participantes de 12 a 15 anos j\u00e1 foram avaliadas no estudo global fase 3, segundo nota, e os dados devem ser submetidos no segundo trimestre deste ano.<\/p>\n

A Pfizer e a BioNTech tamb\u00e9m planejam estudos para avaliar a vacina em pessoas cujo sistema imunol\u00f3gico \u00e9 comprometido.<\/p>\n

A vacina da Pfizer\/ BioNTech contra a covid-19 foi autorizada para uso emergencial nos Estados Unidos pela\u00a0Food and Drug Administration (FDA)<\/strong><\/a>, \u00f3rg\u00e3o que controla os medicamentos utilizados no pa\u00eds, para pessoas acima de 16 anos, mas ainda n\u00e3o foi aprovada para uso permanente.<\/p>\n
