"There will be enough vaccines for all Americans by April.
We'll have 100 million doses by the end of the year," targeting the most at-risk categories.
Donald Trump says so.
Distribution of the coronavirus vaccine will begin within 24 hours of approval:
"There will be enough vaccines for all Americans by April."
Trump stressed that the vaccine "will come shortly and we will defeat the virus".
The vaccine will help save "millions of lives" and return the country to "normalcy".
American health authorities review controversial coronavirus testing guidelines.
And, in a decisive turnaround, they say: tests must be carried out on all those who have come into contact with someone positive for the virus. The US media reported it. Previously, guidelines from the Centers for Disease Control and Prevention stated that tests were unnecessary for people exposed to Covid-19 without symptoms. According to documents and internal sources, however, this recommendation was not formulated by the CDC scientists, who on the contrary pushed to do more tests on the population.
