It is inevitable that some people who have been fully vaccinated against COVID-19 will still get a “breakthrough” infection, Anthony FauciAnthony FauciVaccinated Fauci hosts people at home but stays away from crowded indoor spaces Trump supports Rand Paul for re-election The Hill’s Morning Report – Biden: Let̵
A breakthrough infection is when a person gets a disease despite being vaccinated against it. Fauci noted that there will be hundreds, and perhaps thousands, of cases of fully vaccinated people who become infected with COVID-19.
The key is to compare the small number of infections with tens and eventually hundreds of millions of people who have been vaccinated, Fauci said.
“We see this with all vaccines in real-world clinical trials,” Fauci said during a White House briefing. “No vaccine is 100 percent effective or efficient, which means you will always see groundbreaking infections, regardless of the effectiveness of your vaccine.”
Fauci, director of the National Institute of Allergy and Infectious Diseases, noted that the best example of groundbreaking infections occurs with the flu vaccine. Influenza viruses mutate rapidly, and even during a good year, the shot is only 40 to 60 percent effective.
However, although a vaccine does not protect against infection, it often protects against serious illness.
“If you are vaccinated, you are undoubtedly less likely to get the flu. But even if you get the flu and get sick, vaccination can reduce the severity and duration of the disease and could help you get out of trouble,” said Fauci. .
During the briefing, Fauci also addressed an Israeli pre-pressure survey which made headlines over the weekend, which apparently found that the B.1.351 variant might avoid protection against the Pfizer / BioNTech vaccine.
“With all due respect to my Israeli friends, I think the oppression as it was was as confusing as you could possibly be,” Fauci said. “The only thing that is not confusing is that two doses are really good” if you want to be fully protected.
Fauci said the study made it appear that people receiving two doses of the Pfizer / BioNTech vaccine were more likely to become infected with the B.1.351 variant than people who were not vaccinated at all.
Fauci said the vaccine’s protection means that in the unlikely event that an infection breaks out, it will likely be the “harder variant”, but “that does not mean you have a better chance of getting it.”
