Vaccinated immunocompromised people are more likely to have breakthrough COVID infections leading to hospitalization, according to the CDC’s COVID Data Tracker Weekly Review first reported by the American Lung Association, ATS and Chest.

The ALA/ATS/Chest statement is as follows:

The CDC reports that immunocompromised people account for 44% of hospitalized breakthrough COVID cases. 

“Our organizations urge every eligible person to get vaccinated, to wear a mask in indoor public spaces no matter your COVID-19 vaccination status, and to follow other CDC guidelines like maintaining social distancing, including avoiding crowded indoor spaces, washing your hands often, and staying home if you feel unwell. It is important for everyone to follow CDC guidelines; these recommendations are especially important to protect the immunocompromised population, including those with cancer, who are at higher risk for COVID-19 hospitalization and death, even when vaccinated. 

“Currently, three COVID-19 vaccines are widely available, safe and effectively reduce your risk of severe illness. The Pfizer-BioNTech vaccine, Comirnaty, has recently received full Food and Drug Administration (FDA) approval. 

“Wearing a mask is the best way to minimize the number of droplets and aerosols you inhale and decreases your risk of infection. If you are infected, experiencing mild symptoms or are asymptomatic, wearing a mask reduces your risk of spreading the virus and infecting others. Wearing a mask has no impact on oxygen levels, even for those with chronic lung diseases.” 

“We encourage everyone to wear a mask according to CDC recommendations and to get their COVID-19 vaccine to not only protect themselves, but to protect those for whom the vaccine offers less protection, those who are immunocompromised, and those who can’t get vaccinated, such as children under age 12.”
