The U.S. Food and Drug Administration (FDA) has approved the use of booster dose of Pfizer and Moderna vaccines for the people with weakened immune system. Press office of the FDA reported that on August 13.
The FDA made certain amendments to the licenses for urgent vaccine use; thus, they allowed the extra dose of vaccine for certain categories of people.
The third dose of Pfizer or Moderna will be allowed in at least 28 days after the second shot was made. The FDA assumes that the rest of people are not going to need the third dose.
The booster dose will be available for the people with transplanted organs and weakened immune system. FDA claims that the people with reduced immune response are less capable to recover from infections and disease, including Covid-19, so the booster dose could improve it.
The third shot of anti-Covid vaccine will be necessary in the future so as to boost protection against the infection on the global level. However, most of the healthy and vaccinated people don't neet it yet. Anthony Fauci, the leading American expert in infectious diseases said so as quoted by the New York Times.
Speaking at a press briefing of the work group to combat Covid-19, Fauci said that most of the vaccines provide at least eight months of due protection. He claimed that the US healthcare organizations have been looking into both domestic and international studies on re-vaccination; these measures will be implemented urgently if necessary, he said.
"Federal regulators are expected to authorize as soon as Thursday additional shots for people with weakened immune systems. In an interview last week, Dr. Fauci made the point that, for people with weakened immune systems, “giving them an additional shot is almost not considered a booster, it’s considered part of what their original regimen should have been,” since they need more vaccine to be protected. In contrast, boosters would be used in the broader population to counter any diminution of the vaccines’ protective power", reads the story.
Dr. Fauci added that the U.S. federal authorities have no "immediate plans" to implement the third shot as a must, but they are "actively monitoring different groups for signs of waning protection".
