The US is standing in front of a large turning point in the war with a pandemic when the number of cases and hospitalization plummeted, given thanks to successful vaccination.

"We are rotating the situation," said Jeffrey Zients, the White House Covid-19 response coordinator, said.

With 58% of adults injected at least one vaccine dose and about 113 million (34%) full vaccination, the US was on the way to complete the target of President Joe Biden, of which 70% of the population will be

"I think everyone is tired and wearing a mask can be a troublesome thing. But we are gradually going there and the end of the tunnel ends more and more clearly," Zients said.

Anthony Fauci, the top American epidemiologist, also gave a similar optimism, when it comes to starting to loosen memimation measures of Covid-19 and allow Americans to be able to

"We need to start more freedom when more and more people are vaccinated," said Fauci.

US officials and scientists have a basis for optimism about the prospects of exhausting pandemic thanks to vaccination.

Experts identify these results in part thanks to the successful American vaccination campaign.

One of the evidence shows that the effectiveness of vaccination campaigns in the United States can be seen in Connecticut state.

"What withdrawals here are high-efficiency Covid-19 vaccines and the risk of infection in full vaccine people is very low," said Deidre Gifford, DPH Commissioner, said.

DPH data also shows the infection rate in full vaccinations in Connecticut state less than 0.1%.

In order to implement a fast and efficient vaccination campaign, many experts believe that the effectiveness of vaccines plays an important role.

Pfizer is the first Covid-19 vaccine that approved by FDA on December 11, 2020.

An experiment of the Centers for Disease Control and Prevention (CDC) in the late March, with the participation of 3,950 medical staff and headlines, shows that Pfizer vaccine is up to 90% effectively with people

Moderna is a second vaccine approved by FDA on December 18 last year.

Vaccine Moderna is reported to be effective 94.1% to prevent infected symptoms in unprecedented people.

Some studies also showed that Moderna could resist transformation B.1.1.7 and B.1.351, but scientists are continuing to study this issue.

On February 27, FDA approved the third vaccine in the US is Johnson & Johnson, a vaccine of a syringe developed based on vector vector technology.

This vaccine is also proven to be effective with strains B.1.1.7.

Although obediently obtained the positive results from the vaccination campaign, Jeffrey Zients, the White House Covid-19 response coordinator, said the US was preparing the ability to repeat people who have completed vaccinations

"If the nasal repeats is needed, we will definitely be ready for preventing all the circumstances and have enough supply," he said.

Dr. Fauci also said the ability to specify a seasonal mask will be applied in the coming years to protect American people in the winter disease.

"I think people are used to the fact that wearing a clear mask reduces respiratory diseases," he said.

He added likely that the number of deaths because Covid-19 in the US may be higher than the official report, currently nearly 596,000 people, according to Johns Hopkins University's data.

"I think there is no doubt that we have been counting missing. But this number is a little more than what I think," Fauci talked about 900,000 people died.
