What CDC is doing
CDC is continually assessing how effective COVID-19 vaccines are against this disease. Intensive safety monitoring has been conducted since the first COVID-19 vaccines came out in 2020 and is ongoing.

Respiratory Syncytial Virus (RSV) can cause serious illness in infants, young children, and older adults. RSV season is right around the corner and immunization is an important way to protect against severe RSV.
What CDC is doing
Today, CDC recommended an RSV vaccine for people who are 32-36 weeks pregnant to help protect their babies from severe RSV. CDC has also recommended RSV immunization to protect babies and toddlers. For older adults, CDC recommends an RSV vaccine, using shared clinical decision-making.

What CDC knows
It is unclear how easily BA.2.86 spreads compared to other circulating variants. At this time, BA.2.86 does not appear to be rapidly increasing or driving increases in infections or hospitalizations in the United States.
What CDC is doing
CDC will continue monitoring BA.2.86 and other circulating variants of the virus that causes COVID-19. Moving forward, we will share updates on BA.2.86 when significant additional information becomes available.

What CDC knows
Analysis from CDC’s Center for Forecasting and Outbreak Analytics shows that with the addition of a third virus (COVID-19) that can cause severe illness, even an average respiratory season can place significant strain on our healthcare system.
What CDC is doing
CDC recommends staying up to date on the vaccines recommended for you as an important strategy to prevent severe disease and protect yourself and others around you. Higher levels of vaccination across the population will also help reduce the number of hospitalizations and risk of hospital strain.

What CDC knows
COVID-19 continues to be a major cause of serious respiratory illnesses in the United States, with more than 200,000 deaths (including more than 600 in children and adolescents 0-19 years old) reported since January 2022. Vaccination is the most effective tool to protect yourself from severe illness this fall and winter.
What CDC is doing
CDC recommended a COVID-19 vaccine updated for 2023-2024 for everyone aged 6 months and older to protect against serious illness.

What CDC knows
The U.S. 2023-2024 flu vaccines have a similar vaccine virus composition as the 2023 Southern Hemisphere flu vaccines.

What CDC knows
Early research data from multiple labs are reassuring and show that existing antibodies work against the new BA.2.86 variant.
What CDC is doing
Real-world data are needed to fully understand the impact given the complexities of the immune response to this variant. Studies are ongoing, and we expect to learn more in upcoming weeks.
