This Monday by the United States centers for disease control and prevention, the vaccines produced by the Moderna and Pfizer laboratories are "extremely efficient" in lessening the extent of coronavirus, Also to limiting the disease with an efficiency of 90% once the two doses that build up both vaccines were given. To speed up the vaccination process, the White House has announced that by April 19, 90% of adults in the United States will be eligible to be vaccinated within a five-mile radius of their home.
On Monday, the US president told the nation not to reduce its guards because work against Covid 19 is far over. Since I arrived at the White House, cases have dropped by two-thirds. Still, they are on the rise again, "told the Democratic president, who called on citizens to use masks to return to normalcy.
Only with the first dose of a Pfizer or Moderna vaccine - which requires two inoculations - is 80% effective in preventing infections. The data are based on two weeks of investigations of 4,000 health workers who received their first dose between December 14 and March 13. I am delighted to share information about this new CDC-led study, which has had an impact: Pfizer and modern vaccines to prevent infection, in a press conference, Rochelle Wallensky.
"Wallensky stressed, The study is very promising, who emphasized the effect of residents injecting both doses to reach the highest level of strength toward covid-19, "particularly when our concern about new irregularities" of the virus spreads. . For the CDC director, in a highly dynamic speech, the figures provided by the new study are helping, just it could lead to a new wave of deaths in the United States, similar to the European experience. With an increase in cases that have led to new sanctions in countries are more than 549,000 people have died and higher than 30 million affected by covid-19.
The CDC study coincides with the acceleration of the United States vaccination process, with more than three million doses administered daily. Until last Sunday, 93 million people had received at least one dose of some of the country's vaccines authorized.
On March 11, one year after the pandemic was declared, the United States president called on States to consider all adults as candidates for vaccination no later than May 1, a sign that he was confident that there would be enough doses by then. Biden's goal was symbolic and even patriotic.
Last week, the White House set a new vaccination goal, double the one set when the Democrats came to power on January 20. Biden pledged last Thursday to administer 200 million doses of vaccines in his first 100 days of the presidency (which will be completed at the end of April).
