As\u00ed lo indic\u00f3 un estudio de la Universidad Ben Guri\u00f3n. Es la m\u00e1s aplicada en Israel y es moderadamente menos efectiva contra la mutaci\u00f3n sudafricana.<\/strong><\/em><\/p>\n

La vacuna desarrollada por Pfizer\/BioNTech contra el COVID-19 neutraliza en cerca de un 95 por ciento a la variante brit\u00e1nica B.1.1.7. De ese modo, es casi tan efectiva como la cepa original del virus SARS-CoV-2.<\/p>\n

As\u00ed lo revel\u00f3 un estudio de investigadores de la Universidad Ben Gurion del N\u00e9guev en el que se descubri\u00f3 que la vacuna es moderadamente menos eficaz contra la mutaci\u00f3n sudafricana B.1.351 y las variantes combinadas brit\u00e1nico-sudafricanas.<\/p>\n

La investigaci\u00f3n fue publicada el 20 de marzo en la revista Cell Host and Microbe. All\u00ed, el cient\u00edfico principal Ran Taube del Departamento de Microbiolog\u00eda, Inmunolog\u00eda y Gen\u00e9tica la Facultad de Ciencias de la Salud de la Universidad Ben-Gurion, afirm\u00f3: \u201cNuestros descubrimientos muestran que las variantes futuras podr\u00edan necesitar una vacuna modificada a medida que el virus muta para aumentar su infectividad\u201d.<\/p>\n

Mientras tanto, los investigadores contin\u00faan probando otras variantes circulantes a medida que surgen. Se trata de mutaciones que posiblemente podr\u00edan representar un desaf\u00edo para la efectividad de la vacuna.<\/p>\n

Taube y su equipo tambi\u00e9n evaluaron los niveles de anticuerpos neutralizantes luego de la administraci\u00f3n de una y dos dosis de la vacuna de Pfizer y hallaron que la vacunaci\u00f3n daba una protecci\u00f3n \u00f3ptima en comparaci\u00f3n con los niveles observados en pacientes recuperados.<\/p>\n

En paralelo, el Ministerio de Salud de Israel lleva a cabo estudios sobre las mutaciones conocidas y env\u00eda muestras de todos los hospitales y los cuatro servicios nacionales de salud as\u00ed como al laboratorio nacional central en el Centro M\u00e9dico Sheba.<\/p>\n

Hasta el momento, estos estudios respaldan la investigaci\u00f3n de Ran Taube, que muestra que ninguna de las variantes que circulan en la actualidad es significativamente resistente a la vacuna de Pfizer.<\/p>\n<\/a>

Dona al Fondo de ayuda de United with Israel para luchar contra la grave crisis econ\u00f3mica que sufren millones de israel\u00edes <\/strong><\/a>. Israel es el pa\u00eds con un mayor \u00edndice de vacunaci\u00f3n del mundo, por poblaci\u00f3n. El 50% de los israel\u00edes ya se han vacunado.\r\nAhora es el momento de ayudar a los que m\u00e1s quieres.\r\n\r\n<\/p>

Los israel\u00edes necesitan tu ayuda. Los alimentos y suministros m\u00e9dicos pueden ser escasos. La tasa de desempleo contin\u00faa en un 25%. Comenzamos la crisis con una tasa del 4%\r\n\r\n\u00a0\u00a0<\/p>
