Dr. Fauci spoke about the “occurrence of infection after full vaccination. What do we mean by that?” he asked. “That is the detection of” COVID-19 “14 days after completion of all recommended doses of what would be an FDA EUA authorized vaccine….Infections after vaccination are expected, no vaccine is 100% effective. However, even if a vaccine does not completely protect against infection, it usually if it’s successful protects against serious disease.”
“When you think about vaccines being successful or unsuccessful, a failure, you really have to look at it in multiple subsets,” said Dr. Fauci. “For example, one element of a successful vaccine in one, in which there’s no illness, but there’s no replication of the virus, no dissemination of the virus and clearance of the virus. That is something that is an unusual feat for a vaccine to give —truly what we call sterilizing immunity. Then there’s also within the framework of a successful vaccine, one in which there’s no clinical illness, but there is replication of the virus. It doesn’t disseminate throughout the body….Another element of a successful vaccine is one in which they might be mild illness that really does not interfere with the function of a person. It has replication mild, very mild dissemination, but ultimately the virus is clear….So what we’re talking about when we talk about infection after vaccination, which is clearly being discussed now in the context of the Delta variant, by no means, does that mean that you’re dealing with an unsuccessful vaccine? The success of the vaccine is based on the prevention of illness.” He noted that the Pfizer and Moderna vaccines are “95 and 94%” effective; J&J is 72% effective. But not 100%.
“What we’re really dealing with is effectiveness against serious disease, leading to hospitalization, and in some cases, death, and since the Delta variant is now 83% in this country, it’s the one we’re dealing with. So even though we are seeing infections after vaccination referred commonly to as breakthrough infections, the effectiveness against the severe disease is still substantial, which is yet again, another argument which all of us say continually get vaccinated. It offers good protection against disease.”
A reporter asked after Fauci spoke if it was possible to get Long COVID after vaccination. That can result in long-term fatigue, migraines, brain fog and other debilitating issues; an estimated 30% of unvaccinated people who got COVID got Long COVID. “That’s an object of a very intensive study right now, following individuals with various levels of seriousness of disease as to what the incidents and prevalence will be of long COVID,” said Dr. Fauci. “We don’t have enough information right now to give you an accurate number of what that incidence is, but that’s something that is being very actively followed right now.” Fauci in the past has not been able to say exactly how much COVID you could spread to someone—say, your unvaccinated child—after vaccination.

Follow Fauci’s fundamentals and help end this pandemic, no matter where you live—get vaccinated ASAP; if you live in an area with low vaccination rates, wear a face mask that fits snugly and is double layered, don’t travel, social distance, avoid large crowds, don’t go indoors with people you’re not sheltering with (especially in bars), practice good hand hygiene, and to protect your life and the lives of others, don’t visit any of these 35 Places You’re Most Likely to Catch COVID.
