The U.S. government announced Wednesday that it plans to make it widely available to all Americans. booster doses vaccines against coronavirus, starting on September 20, as infections increase from Delta mutation.
The White House is ready to offer a third boost from this date to all Americans who have completed at least one initial vaccination. eight months ago, according to international news agencies, cited by the country’s Ministry of Health.
Commemorative doses will be given at first mainly to health professionals, nursing home inmates and the elderly, according to APE NTUA. All of these categories were among the vaccinated groups first in late 2020 and early 2021.
Top US health officials have said in a joint statement that they base their decision to grant boosts on evidence that Covid-19 vaccine protection, approved in the US, begins to decline months after vaccination.
Among the officials is President Joe Biden’s top medical adviser Anthony Fauci as well as the heads of the Centers for Disease Control and Prevention (CDC), the US Food and Drug Administration (FDA) and the National Institutes of Health.
«The available data make it very clear that protection against SARS-CoV-2 infection begins to decrease over time (…) and in combination with the dominance of the Delta variant, we begin to see signs of reduced protection against mild to moderate disease.“, The officials emphasize.
“We conclude that a booster dose will be needed to maximize protection against vaccines and extend its resistance,” they say.
Any decision, however, depends on the approval of an additional dose of Pfizer and Moderna vaccines by the US Drug Enforcement Administration (FDA), they note.
About the Johnson & Johnson vaccine
Officials also said they expect those who received the single-dose vaccine to Johnson & Johnson against COVID-19 booster doses will also be needed.
However, vaccinations with this vaccine began in the US “in March 2021” and the data about them expected “Within the next few weeks”.
What the WHO says
The existing data not The World Health Organization (WHO) has said that booster doses of coronavirus vaccines are needed, adding that the most vulnerable people in the world should be fully vaccinated before high-income countries get additional vaccinations.
The leading scientist of the WHO Sumia SwaminathanAsked about the need for booster doses to increase protection against the disease, he told a news conference in Geneva today: “We clearly believe that the evidence today does not indicate the need for booster doses.”
Further research is needed, she added.
For his part, the top adviser of the WHO Bruce Ellward“There are several vaccines around the world, but they do not go in the right places in the right order,” he told reporters, referring to booster doses in high-income countries.
“Two doses should be given to the most vulnerable in the world, before booster doses are given to fully vaccinated people,” he said.We are very, very far from that».
It is recalled that a number of countries in the EU have reached a decision to administer a third dose of the Covid-19 vaccine to people with reduced immunity.
In GREECE
And to Hellas announcements are expected in the next few days on the issue of a third dose of the Covid-19 vaccine. According to information, this opportunity will be given to citizens with reduced immunity (immunosuppressed, oncology patients, etc.).
The chairman of the Vaccination Committee made an extensive report on the issue of the third dose of the vaccine on Monday, during the regular briefing. “We have all heard from the media that there is a strong interest in the possibility of a third dose of Covid vaccine. For which third dose the test term is booster dose. Because it is also referred to by some as an experimental dose.
The immune response to vaccination with studies of both chemical immunity, ie antibodies, and cellular, the determination of T-lymphocytes, has been the main research project of scientific centers abroad and in our country. Indicatively, I mention the remarkable studies that have been published abroad by the research teams of the National Kapodistrian University, in collaboration with the Onassis Cardiology Center, by professors Dimopoulos, Boleti, Hatzaki, Psychogiou and others to whom I can not apologize. everyone.
The studies of the researchers in our country have included in the control groups, groups with hematopoietic cell transplants, solid organs, people with neoplasms, people on dialysis, as well as health workers of different ages.
According to studies, in these special population groups, it seems that after six months the level of antibodies decreases significantly.
Particularly troubling immunosuppressed due to disease or treatment“, Said, among others, Mrs. Maria Theodoridou.
THE National Vaccination Committee, in order to give an opinion on the possible granting of an auxiliary dose in our country, asked for “the views and positions of the medical scientific companies and the response was really immediate and extremely constructive. The opinion, as always, will be based on data from post-vaccination immune response studies and epidemiological data our country. That is, serious infections despite vaccination, hospitalization or death.
It should be noted that to date not “There are data that prove the need to give a booster dose to the vaccinated of the general population”, the professor also pointed out in the relevant statements of the day before yesterday.
