During their virtual summit which ended on Sunday, the leaders of the G20 are committed to be guaranteed “affordable and equitable access for all” vaccines.
The World Health Organization (WHO) has already identified 48 candidate vaccines, including 11 which are in the final stages of testing on tens of thousands of volunteers around the world.
The US-German alliance Pfizer / BioNTech first claimed on November 9 that its vaccine is 90 percent effective. Two days later, the Russians from the Gamaleïa institute went up with 92% efficiency.
Then it is the turn of another American company, Moderna, to ensure that the effectiveness of its product is 94.5%. Two days later, Pfizer / BioNTech revised upwards the results of its clinical trials with an announced efficacy of 95%.
Hope is therefore permitted, but questions remain unanswered: do these vaccines outright prevent the transmission of the coronavirus? How long will their protection last? What are their side effects?
In the United States, senators have volunteered to participate in clinical trials in the hope of reassuring the public, many of whom, “anti-vaxxers”, remains suspicious of vaccines.
This is the case, for example, of Senator Rob Portman, a Republican who represents the State of Ohio. He participated in clinical trials conducted by the multinational Johnson & Johnson team.
Another Republican senator, Steve Daines of Montana, chose to participate in the Pfizer trials. “It’s about restoring hope. It’s about restoring normalcy in our way of life.”, he told Fox News.
However, WHO emergency officer Michael Ryan warned on Wednesday that vaccines will not arrive in time to tackle the second wave of the pandemic, and many countries are expected to prepare to “face it without vaccines”.
According to the expert, it will take “at least four to six months” before there are sufficient levels of immunization.
