Trenutna situacija o razvoju vakcine
Of the more than 155 vaccines in development around the world, only four have reached Phase 3, according to The Times’s vaccine tracker. (The Chinese military issued the first approval for a vaccine last month, but only for limited use.) |
But at least three more potential vaccines appear ready to enter Phase 3. |
One, made by the biotech company Moderna, provoked an immune response in 45 people in a studypublished this week — and it did so safely and without serious side effects. The company announced yesterday that it would begin Phase 3 testing in 30,000 people later this month, to be completed by late October. |
Russian scientists hailed another potential vaccine as safe and effective this week, and said it would enter Phase 3 in mid-August. And in an interview with Meridian Magazine, an executive director for pharmaceutical sciences at Pfizer said the company would begin a Phase 3 trial with one of its vaccine candidates later this month and, assuming it is positive, have 200 million doses ready by November. |
Experts agree that we’ll need multiple vaccines because no single company can quickly produce the billions of doses the world needs. |
