Arriva in Svizzera un vaccino contro la febbre dengue. Alla fine di luglio Swissmedic ha infatti omologato il preparato Qdenga del fabbricante Takeda Pharma AG, dopo averne verificato efficacia, sicurezza e qualità, come si legge in una nota diffusa venerdì. Finora in Svizzera non esisteva un vaccino contro tale malattia virale.
La somministrazione è raccomandata alle persone con più di quattro anni che si recano in zone in cui è diffusa la febbre dengue, prevalentemente aree subtropicali e tropicali in Africa centrale, America Latina, India e sud-est asiatico. La malattia è presente anche nel sud degli Stati Uniti (Texas).
Il preparato – spiega Swissmedic - contiene versioni attenuate di quattro varianti del virus, che non sono in grado di causare la malattia ma inducono il sistema immunitario a produrre i relativi anticorpi.
La malattia viene trasmessa da zanzare infette (principalmente zanzare della febbre gialla e zanzare tigre asiatiche) e di solito insorge da quattro a sette giorni dopo la puntura.
