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".
According to the expert, Delta strain caused the new global outbreak of the infection; he also provided new data, which confirms that Johnson & Johnson vaccine is just as effective against it as the others.
WHO Director General Tedros Adhanom Ghebreyesus urged the governments to put the re-vaccination campaign on hold until September to make sure that at least 10 percent of population in every country can get these boosters. “I understand the concern of all governments to protect their people from the Delta variant. But we cannot — and we should not — accept countries that have already used most of the global supply of vaccines using even more of it, while the world’s most vulnerable people remain unprotected,” he said.
