It is expected that from the week of September 20, all American adults can receive the booster shot. Fearing that the effectiveness of the vaccine will decline over time, Americans may soon be given a third shot of the new crown vaccine.On August 18, local time, the Biden government issued a statement stating that it will provide all Americans with a booster shot of the new crown vaccine. The US government recommends that all Americans who have been vaccinated with Pfizer or Moderna vaccine should receive a third booster dose approximately 8 months after the second shot.

It is expected that from the week of September 20 this year, all American adults can receive the booster shots-this proposal was jointly signed by several senior health officials in the United States, including the Director of the Centers for Disease Control and Prevention (CDC) Wallensky (Rochelle Walensky) and White House Chief Medical Adviser Anthony Fauci.
On the same day, the Director-General of the World Health Organization (WHO) Tan Desai said at a briefing: “I call for the suspension of the vaccination booster injection to help transfer the vaccine supply to other countries. Those countries cannot even provide medical workers and high-risk communities. Vaccinated and are now experiencing a severe peak in case growth.”
Tan Desai said that at present, three-quarters of the world‘s vaccine supply is vaccinated by 10 countries, while only 2% of the population in low-income countries have been vaccinated.
The United States plans to start the third dose of vaccination from September 20
The US government’s recommendation states: “According to the latest assessment, the current (new crown vaccine) protection against severe illness, hospitalization, and death may be reduced in the next few months. Those who are at a higher risk or have been vaccinated in the early stages of vaccine promotion. This is especially true of the population. For this reason, we have concluded that booster injections will be needed to maximize the protective effects induced by the vaccine and prolong its durability.”
Fauci said that the data shows that the antibodies provided by the vaccine will decline over time, and higher levels of antibodies may be required to prevent the more transmissible “delta” strain from spreading across the United States. A study tracking adults in New York State found that the effectiveness of the new crown vaccine against infection fell from 91.7% in early May to 79.8% in late July. During the same period, the state experienced an increase in infections caused by the more transmissible “delta” strain.
Valensky also cited data collected by the Mayo Medical Center in the United States, saying that Pfizer and Modena vaccines are less effective in protecting against infection by the “Delta” strain. The effectiveness of Pfizer’s vaccine has dropped from 76% of the early version of the new coronavirus to 42% against the “Delta” strain, and the effectiveness of the Modena vaccine has dropped from 86% to 76%. U.S. officials also studied similar data from Israel. Relevant data showed that with the emergence of the “Delta” strain, the anti-infective effect of the new crown vaccine dropped from about 95% in June to 64% in July.
Vivek Murthy, Chief Medical Officer of the U.S. Public Health Service, was also one of the senior officials who signed the proposal. According to recommendations, from the week of September 20th, people 18 years and older should get a third dose of Pfizer and Modena vaccines. He said that the booster shot of the new crown vaccine will first be provided to vulnerable people who received the first shot at the beginning of this year, including medical workers, residents of nursing homes, residents of long-term care institutions and other elderly people.
According to US media analysis, the call for enhanced injections marked a turning point in the Biden administration’s vaccine strategy. At the beginning of this summer, Biden announced a plan to restore normal economic order in the United States by July 4. But in the past month, as the “Delta” strain spread across the United States, the U.S. government had to withdraw this plan and required vaccinated Americans to wear masks again indoors.
In the next step, the US Food and Drug Administration (FDA) will also evaluate the safety of the third dose of Pfizer and Modena’s new crown vaccine. In addition, US health officials said they expect Johnson & Johnson’s vaccine will also be recommended for booster shots, but more research is needed before a decision is made.
The White House pandemic response coordinator, Jeff Zients, said that the booster injection of the new crown vaccine is provided free of charge to all Americans. Zienz pointed out that the United States has enough vaccines for all Americans, and booster shots will be provided at approximately 80,000 locations across the country.
However, Zienz also pointed out that the Biden administration is still committed to persuading more Americans to get their first dose of vaccine. “This pandemic is still mainly aimed at people who have not been vaccinated.” He added that as the “Delta” strain continues to spread across the United States, the vaccination rate has been rising in recent weeks.
In the past two weeks, nearly 7 million Americans have chosen to get their first dose of vaccine, setting the fastest rate of first dose since June this year.
According to CDC data, as of August 18, nearly 40% of American adults still have not completed the vaccination.
WHO opposes
Tan Desai said that last week, the WHO convened 2,000 experts from all over the world to debate the current data on vaccine boosters. “It is obvious that before the booster needle is introduced, it is crucial to inject the first needle into people’s arms and protect the most vulnerable people,” he said.
“The virus is constantly evolving. When we live in an interconnected world and the virus is rapidly mutating, it is not in their best interest for leaders to focus solely on narrow nationalist goals. In fact, strong national leadership It means full commitment to vaccine fairness and global solidarity, which will save lives and slow down mutations.” Tan Desai said.
Tan Desai also said: “Vaccine unfairness is a pity for all mankind. If we do not solve this problem together, we will prolong the severe epidemic stage to several years, and it might have ended in a few months. “
“Under this situation, I am shocked by the news that Johnson & Johnson’s vaccine, which was bottled and finished in South Africa, is leaving the African continent for Europe. In Europe, almost all adults have received it at this time. Vaccines.” Tan Desai also urged that Johnson & Johnson should give priority to the distribution of vaccines to Africa before considering providing vaccines to wealthy countries that already have sufficient supplies.
In response, Biden government officials said they are committed to protecting Americans and donating vaccines worldwide. Morsi said: “I do not accept the view that we must choose between the United States and the world.”
“We will continue to do our best to get more people vaccinated, whether in the United States or around the world,” Zienz said. “We can and must do both at the same time, because this is the end of this big The necessary conditions of the epidemic, we will not stop until we complete the task.”
