The delta variant is concerning because it's more highly transmissible, but the good news is that the COVID-19 vaccine is still highly protective against getting infected or ending up in a hospital or dying from the infection. Breakthrough infection is a rare event where someone who is fully vaccinated still ends up getting infected with COVID-19.

The delta variant was declared a “variant of concern” by the World Health Organization in May. The designation is used when there is increased evidence that a variant is more transmissible, causes more severe illness or reduces the effectiveness of vaccines or treatments. In the U.S., the CDC declared delta a “variant of concern” on June 15. Resear...
It’s not unusual for a virus to mutate and evolve as it spreads, and scientists have long cautioned that other worrisome variants could emerge with new outbreaks. In India, researchers observed mutations separate from delta in a sublineage of the virus that they dubbed “delta plus.” While it has not yet been designated a variant of concern by the W...
More research is needed, but there are indications that the delta variant may cause more severe disease. A study published June 14 in thejournal The Lancetexamined the impact of the delta variant in Scotland, where it had become the dominant strain. The researchers found that the risk of hospitalization from Covid-19 was roughly doubled for patient...
The delta variant has been reported in more than 95 countries, according to the World Health Organization. “Every country that it has gone into up to now, you’ve seen an escalation in cases where it’s pushed aside the variant that was dominant before it,” Fauci said Tuesday in aninterview with NBC’s Nightly News. Cases involving delta have been con...
The vaccines in use appear to offer good protection against the delta variant, and most scientists agree that fully vaccinated individuals likely face little risk. Moderna announced Tuesday that its vaccine is effective against the delta variant. The results were based on blood samples from fully vaccinated people and showed that these individuals ...
In response to the spread of the delta variant, the WHO advised that people, regardless of their vaccination status, should continue to wear masks. The CDC has meanwhile stood by its guidance that says fully vaccinated people can largely forgo masks, though the agency acknowledged that local rules may change based on the situation on the ground. Ea...
Jun 22, 2021 · Delta, formally known as B.1.617.2, is believed to be the most transmissible variant yet, spreading more easily than both the original version of the virus and the Alpha variant...
Oct 18, 2021 · Delta offers a tougher challenge. Early in the infection, when people are most likely to be contagious, the Delta variant seems to replicate in amounts that are perhaps 1,000 times as much as...

The Delta variant (B.1.617.2) was [3] [4] a variant of SARS-CoV-2, the virus that causes COVID-19. It was first detected in India on 5 October 2020. The Delta variant was named on 31 May 2021 and had spread to over 179 countries by 22 November 2021.
Jul 14, 2021 · Delta is believed to be the most transmissible variant yet. It may also be able to partially evade the antibodies made by the immune system after a coronavirus infection or vaccination. Several...
Aug 5, 2021 · According to an internal CDC document, the Delta variant – one of four “variants of concern” that have evolved from SARS-CoV-2, the virus that causes COVID-19 – is more than twice as infectious as the original virus and as infectious as chickenpox. Denise Barchas, RN, works in the ICU respiratory isolation room at UCSF Mount Zion Medical Center.
