It’s when a fully vaccinated person gets infected with the coronavirus.
The issue is the unvaccinated population. In the U.S., people who weren’t vaccinated make up nearly all hospitalizations and deaths from COVID-19 — what remains clear is the vaccines are working – the main reason to get vaccinated.
The other issue is the Delta variant, which is the dominant variant globally and more contagious than the Alpha variant. CDC’s new data shows people who get infected by the Delta variant could carry enough virus in their noses and throats to spread it to others. CDC Delta variant information
There are more vaccine candidates simultaneously in the pipeline for COVID-19 than ever before for an infectious disease. All of them are trying to achieve the same thing – immunity to the virus, and some might also be able to stop transmission. They do so by stimulating an immune response to an antigen, a molecule found on the virus. In the case of COVID-19, the antigen is typically the characteristic spike protein found on the surface of the virus, which it normally uses to help it invade human cells.
As coronavirus cases once again rise in the U.S., experts say breakthrough cases will also go up, but that doesn’t mean the vaccines aren’t working. A series of recent coronavirus infections among vaccinated athletes and government staffers has focused attention on an apparent rise in so-called breakthrough infections. But while cases involving fully vaccinated people have increased in recent weeks, experts say there’s little reason to worry. But as the pandemic continues to linger and more transmissible variants, such as the Delta variant, the virus will circulate widely, it’s expected that the number of breakthrough infections will rise.
Here’s what to know about breakthrough cases in the context of the Delta variant and what scientists are doing to track the vaccines’ efficacy: you can get COVID-19 even if you’re vaccinated, but it’s rare and likely to be mild. Don’t panic. Research shows the current vaccines are holding up well against the delta variant. For instance, data from the U.K. suggests the Pfizer vaccine is 88% effective at preventing symptomatic COVID-19 from the delta variant after two doses. And an earlier study from the U.K. found it is 96% effective against hospitalization. Bottom line: Vaccination is still key.
Getting COVID-19 when you’re vaccinated isn’t the same as getting COVID-19 when you’re unvaccinated. With the rise of the über-transmissible Delta variant, experts are saying you’re either going to get vaccinated, or going to get the coronavirus. Coronavirus infections are happening among vaccinated people. They’re going to keep happening as long as the virus is with us, and we’re nowhere close to beating it. When a virus has so thoroughly infiltrated the human population, post-vaccination infections become an arithmetic inevitability. As much as we’d like to think otherwise, being vaccinated does not mean being done with SARS-CoV-2.
Coronavirus cases are again surging across this country. While the CDC reports that over 97% of the people hospitalized with new cases had not been vaccinated, there is a growing number of something called breakthrough infections or infections among vaccinated people. This episode will look deeper into Provincetown, Mass. outbreak with more than 250 people contracted COVID.
Vox’s Umair Irfan explains why the United States is seeing another Covid-19 surge. Dr Rhea Boyd says the country is getting unvaccinated people all wrong.
Dr John Torres discusses with Dr Angela Rasmussen, a virologist and research scientist at the Vaccine and Infectious Disease Organization at the University of Saskatchewan, about coronavirus immunity, vaccine effectiveness, and variants.
While Covid-19 vaccinations are highly effective at preventing hospitalizations or death from the virus, they’re not foolproof in preventing infection. This poses problems for events like the Olympics and raises broader questions about immunity in the long term.
