Cholera Vaccine: Recommendations of the Advisory Committee on Immunization Practices, 2022

A CDC report that summarizes recommendations from the Advisory Committee on Immunization Practices for the use of lyophilized CVD 103-HgR vaccine in the United States. Cholera is a toxin-mediated bacterial gastrointestinal illness caused by Vibrio cholerae serogroup O1.

The figure is a graphic with text that reads, “Recommend the cholera vaccine for your patients based on their travel plans and age.” There are three boxes that explain why, where, and to whom the vaccine should be recommended. It says, “Up to 10% of cholera infections are severe, resulting in diarrhea that can cause severe dehydration and rapid death. Travelers should receive the cholera vaccine before traveling to places with active cholera transmission. The cholera vaccine is recommended for travelers ages 2–64 years old.”

Effectiveness of a Second COVID-19 Vaccine Booster Dose Against Infection, Hospitalization, or Death Among Nursing Home Residents — 19 States, March 29–July 25, 2022

In a large cohort of nursing home residents, receipt of a second mRNA COVID-19 booster dose during circulation of SARS-CoV-2 Omicron subvariants was 74% effective at 60 days against severe COVID-19–related outcomes (including hospitalization or death) compared with receipt of a single booster dose.



The figure is a bar chart showing the percentage of residential care communities in the United States during 2016 and 2020 that use electronic health records, by community bed size.
