The UK strain has become the most prominent strain of COVID in the United States, the CDC said.

All three of the licensed vaccines worked effectively.

CDC Director Rochelle Walensky said on Wednesday.

“Based on our latest forecasts from the CDC surveillance, the B-1

17 is now the most common pedigree in the United States,” Walensky told reporters at a White House briefing.

Walensky’s comments are on schedule, with earlier predictions that the Model B-117 will become a more dominant breed by late March or early April.

Walensky did not specify on Wednesday how unique the B-117 is, but a CDC spokesperson said she cited preliminary information that has not been disclosed. But it shows that the B-117 is the most dominant species.

This is followed by the latest CDC data available in the case through March 13, which shows a more than doubled percentage of B-117 cases from late February to mid-March.

At the end of February, the B-117 variant accounted for about 11% of all cases, but by mid-March that increased to 27%.

Experts believe the B-117 variant is more contagious and tends to be more life-threatening, which could help explain why the increased prevalence in the United States is coinciding with an increase in cases despite speed. In vaccination, which has proven to be effective with the

“We know some of these increases are due to higher transferable variables that we are monitoring very closely,” Walensky said at a White House briefing earlier this week. As of Wednesday, the CDC reported an average of 62,000 cases per day over the past seven days.

In addition to the new, more invasive model, experts say relaxed COVID-19 restrictions and increased travel are to blame for the growing number of cases.

While nearly half of US adults are partially immunized. But now the virus is spreading among young people who have not yet received it, Walensky said. The big one comes from the daycare center and youth sports.

All three vaccines licensed in the United States – Pfizer, Moderna and Johnson & Johnson – have been proven to work as effective as the B-117 variant.

The vaccine is also expected to provide immunity for at least six months and possibly longer. Anthony Fosi, the country’s chief infectious disease specialist, said at a briefing on Wednesday.

Although all vaccines are highly effective But experts say only time will tell how long that protection will last. Fauci added another level of hope Wednesday, saying studies show that immunity tends to be “too good” by six months.

Walensky urges Americans to “Roll up your sleeves” and join 45% of adults who have been vaccinated once, warning that in each case there is a greater chance that the virus will mutate and become a problem.

“Sixty-five thousand cases, that is a 65,000 chance for the upcoming mutations to have more proliferation, so we’re just watching this very carefully,” she said.

“I would like to wrap up with two important facts right now,” she said. “There is still reason we have to worry about the increase in the number of patients, the incremental shifts and visits to the hospital.” The hospital is on the rise and there are many reasons for hope. “
