Although vaccines are highly effective, they are not perfect, and there will be vaccine breakthrough infections. Vaccines are playing a crucial role in limiting spread of the virus and minimizing severe disease.For all people, the vaccine provides the best protection against serious illness and death.

But they are not 100% effective, and some fully vaccinated people will become infected (called a breakthrough infection) and experience illness. The COVID-19 vaccines approved or authorized in the United States are highly effective at preventing severe disease and death, including against the Delta variant.Vaccines in the US are highly effective, including against the Delta variant This means fully vaccinated people will likely spread the virus for less time than unvaccinated people.

However, like prior variants, the amount of viral genetic material may go down faster in fully vaccinated people when compared to unvaccinated people. For people infected with the Delta variant, similar amounts of viral genetic material have been found among both unvaccinated and fully vaccinated people.

However, vaccinated people appear to spread the virus for a shorter time: For prior variants, lower amounts of viral genetic material were found in samples taken from fully vaccinated people who had breakthrough infections than from unvaccinated people with COVID-19. Fully vaccinated people with Delta variant breakthrough infections can spread the virus to others.CDC is continuing to assess data on whether fully vaccinated people with asymptomatic breakthrough infections can transmit the virus. People infected with the Delta variant, including fully vaccinated people with symptomatic breakthrough infections, can transmit the virus to others. Fully vaccinated people get COVID-19 (known as breakthrough infections) less often than unvaccinated people. Unvaccinated people remain the greatest concern: The greatest risk of transmission is among unvaccinated people who are much more likely to get infected, and therefore transmit the virus.Even so, the vast majority of hospitalization and death caused by COVID-19 are in unvaccinated people. In two different studies from Canada and Scotland, patients infected with the Delta variant were more likely to be hospitalized than patients infected with Alpha or the original virus that causes COVID-19. Some data suggest the Delta variant might cause more severe illness than previous variants in unvaccinated people.The Delta variant is more contagious: The Delta variant is highly contagious, more than 2x as contagious as previous variants.More information will be made available when more data are published or released in other formats. Below is a high-level summary of what CDC scientists have recently learned about the Delta variant. This includes recently published data from CDC and our public health partners, unpublished surveillance data that will be publicly available in the coming weeks, information included in CDC’s updated Science Brief on COVID-19 Vaccines and Vaccination, and ongoing outbreak investigations linked to the Delta variant.ĭelta is currently the predominant variant of the virus in the United States. Second, new data began to emerge that the Delta variant was more infectious and was leading to increased transmissibility when compared with other variants, even in some vaccinated individuals. This case rate looked more like the rate of cases we had seen before the vaccine was widely available. On July 27, the 7-day moving average of cases reached over 60,000. In late June, the 7-day moving average of reported cases was around 12,000.In the days leading up to our guidance update, CDC saw a rapid and alarming rise in the COVID-19 case and hospitalization rates around the country. CDC issued this new guidance due to several concerning developments and newly emerging data signals.įirst, a significant increase in new cases reversed what had been a steady decline since January 2021. On July 27, 2021, CDC released updated guidance on the need for urgently increasing COVID-19 vaccination coverage and a recommendation for everyone in areas of substantial or high transmission to wear a mask in public indoor places, even if they are fully vaccinated.
