اثربخشی بیش از ۸۳ درصدیِ آسترازنکا در افراد بالای ۶۵ سال

در آزمایش‌های بالینی روی میزان مصون سازی واکسن آسترازنکا در آمریکا، این واکسنِ تولیدی دانشگاه آکسفورد و شرکت دارویی آسترازنکا، ۷۴ درصد تاثیرگذاری را نشان داده است و این رقم در افراد ۶۵ سال به بالا به ۸۳.۵ درصد افزایش می‌یابد.

  این آزمایش بالینی روی ۲۶ هزار داوطلب در ایالات متحده، شیلی و پرو انجام شد که دو دُز واکسن را با فاصله حدود یک ماه دریافت کردند. نتایج این آزمایش در مجله پزشکی نیوانگلند منتشر شد.
در بین بیش از ۱۷ هزار و ۶۰۰ نفری که واکسن دریافت کرده‌اند هیچ موردی از علائم شدید یا بحرانی کووید-۱۹ مشاهده نشده است در حالیکه در بین ۸۵۰۰ نفری که دارونما دریافت کرده بودند، هشت مورد کووید شدید مشاهده شد. همچنین دو نفر در گروه دارونما جان خود را به خاطر این بیماری از دست دادند اما هیچ فردی در بین کسانی که واکسن تزریق کرده بودند، فوت نشدند.
از سوی دیگر در این آزمایش بالینی هیچ موردی از عارضه نادر لخته شدن خون پس از تزریق واکسن آسترازنکا گزارش نشده است.
شرکت سوئدی آسترازنکا در اواخر ژوئیه گفته بود که قصد دارد به جای درخواست مجوز استفاده اضطراری، برای گرفتن تاییدیه کامل به سازمان غذا و داروی ایالات متحده مراجعه کند.
به گزارش یورونیوز، واکسن آسترازنکا مجوز استفاده در بیش از ۱۷۰ کشور جهان را کسب کرده است.
