Pfizer has confirmed that its vaccine will require a third dose

The third dose will be needed no later than nine months or one year later. A new dose will be needed a year or 18 months later, as with seasonal flu. “It will be a way to strengthen protection,” adds the doctor.

On the other hand, the professional was convinced of the effectiveness of his vaccine against the variant of COVID-19 detected in India, despite the fact that tests in the matter are still underway. “The Indian variant has mutations that we have already studied and that our vaccine works against, which gives us confidence,” he said.
