Article Synopsis
- SARS-CoV-2 Omicron variants may affect how well vaccines work and how long immunity lasts, prompting a study on the effectiveness of the Pfizer-BioNTech vaccine among different age groups in the U.S.
- From January 16 to May 28, 2022, researchers analyzed COVID-19 infection rates relative to vaccination status across multiple jurisdictions, tracking declines in vaccine effectiveness over time.
- Results showed lower vaccine protection in younger age groups, particularly those aged 5-11, and a general decline in effectiveness for all ages as time since vaccination increased, indicating a need to monitor waning immunity during the Omicron surge.
Article Synopsis
- Reinfections of SARS-CoV-2 in the U.S. have become more common, especially during the Omicron variant period, rising from 2.7% during Delta to 28.8% in Omicron BQ.1/BQ.1.1.
- Hospitalizations and deaths linked to reinfections also increased significantly, going from 1.9% and 1.2% of COVID-19-related cases during Delta, to 17.0% and 12.3% during Omicron BQ.1/BQ.1.1.
- Younger adults (18-49 years) had higher rates of reinfections compared to older adults (≥50 years), and it's crucial to stay updated on vaccinations
Objectives: On September 23, 2019, the North Carolina Division of Public Health identified a legionellosis increase in western North Carolina; most patients had recently attended the North Carolina Mountain State Fair. We conducted a source investigation.
Methods: Cases were fair attendees with laboratory-confirmed legionellosis and symptom onset within 2 to 14 days (Legionnaires' disease) or ≤3 days (Pontiac fever).
