Question: What should I know about the B.1.617.2 (Delta) variant of SARS-CoV-2?
Answer: The Delta variant was first detected in the United States in March 2021. It was initially identified in India in December 2020. These variants seem to spread more easily and quickly than other variants, which may lead to more cases of COVID-19. An increase in the number of cases will put more strain on healthcare resources, lead to more hospitalizations, and potentially more deaths.
So far, studies suggest that the current authorized vaccines work on the circulating variants. Scientists will continue to study these and other variants. To learn more, visit the CDC website
Question: Why is it important to get vaccinated?
Answer: COVID-19 vaccinations are an important way to protect yourself and your family. In the short term, you can keep those who are older and who have other underlying conditions from becoming severely ill and potentially hospitalized.
In the longer term, vaccines reduce viral replication in the community. The more people who become infected, the greater the risk of additional variants developing. And variants can weaken the strength of vaccines, resulting in a need for constant updates and refinements. It is critical to prevent the virus from spreading and replicating in the first place.
Question: Do any of the COVID-19 vaccines authorized for use in the United States shed or release any of their components?
: No. Vaccine shedding is the term used to describe the release or discharge of any of the vaccine components in or outside of the body. Vaccine shedding can only occur when a vaccine contains a weakened version of the virus. None of the vaccines authorized for use in the U.S. contain a live virus. mRNA and viral vector vaccines are the two types of currently authorized COVID-19 vaccines available.
