The advisory group of the Centers for Disease Control and Prevention voted unanimously on Sunday, suggesting that the federal government prepares to use Johnson & Johnson̵
Once the Director of the Centers for Disease Control and Prevention, Dr. Rochelle Walensky, accepts the recommendation of the Immunization Practice Advisory Committee, the federal government will be able to begin shipping doses across the country. ACIP met at an emergency meeting to review the data on the vaccine, which was on Saturday Became the third gun authorized by the U.S. Food and Drug Administration (FDA) for emergency use.
Valensky said Friday that she would “stand by” ACIP’s proposal and “prepare to sign.”
“We are eager to use another vaccine Johnson & Johnson Covid-19 vaccine in our toolbox. Like many of you, I’m excited about the news that another safe and effective vaccine option may come out as soon as next week. “,” she said Friday. “Having another safe and effective vaccine will help protect more people faster.”
Johnson & Johnson’s vice president of medical affairs, Dr. Richard Nettles, told lawmakers on Tuesday that the company intends to ship nearly 4 million doses immediately after receiving emergency use authorization. He added that the company expects to be able to provide 20 million doses by the end of March.
The launch of Johnson & Johnson’s vaccine may be of great benefit to the US vaccine supply. Although compared with Pfizer-BioNTech and Moderna vaccines, the new vaccine has shown inferior efficacy in preventing Covid-19 in clinical trials, but Johnson & Johnson’s injection vaccine is 100% effective in preventing deaths and hospitalizations caused by Covid-19. Effective trial.
According to FDA documents released on Wednesday, the level of protection of Johnson & Johnson vaccine against Covid-19 in trials varies from region to region. About one month after vaccination, the vaccine is 72% effective in the United States, 61% in Latin America, and 64% in South Africa, and the B.1.351 variant is rapidly spreading.
It is worth noting that the FDA review shows that the vaccine is significantly less effective in people who are 60 years old and older with diabetes or heart disease and other comorbidities. However, the agency pointed out that the data is too sparse to draw conclusions from it.
On the contrary, it was found in clinical trials that Pfizer’s vaccine is 95% effective against Covid-19, while the Moderna vaccine has an effective rate of 94%. Infectious disease experts pointed out that Johnson & Johnson’s numbers cannot be directly compared with the other two vaccines because it is a single dose and the company’s trials are conducted when there are more infections and new, more infectious variants.
But federal health officials pointed out that the one-time Johnson & Johnson program has unique logistical advantages that may make it an ideal choice for hard-to-reach populations.
Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases of the CDC, told the Journal of the American Medical Association during a question-and-answer event on Friday that Johnson & Johnson’s vaccine “makes it easier to operate in many situations.” “I hope the state health department has a lot of consideration around these vaccines, more about the ease of use of Johnson & Johnson vaccines and how to make them more suitable for certain groups of people.”
Johnson & Johnson has stated that it plans to ship the vaccine at 36 to 46 degrees Fahrenheit. The vaccine contains five doses per vial. In contrast, Pfizer’s vaccines usually need to be stored in ultra-cold refrigerators to keep their temperature between 112 degrees Fahrenheit and minus 76 degrees Fahrenheit, although the FDA recently stated that they can be stored at standard pharmacy freezing temperatures for up to two weeks. . Moderna’s vaccine needs to be transported at a temperature between 13 degrees below 0 degrees Fahrenheit and above 5 degrees Celsius.
