Can I still get COVID-19 even if I'm vaccinated?
Yes, current vaccines provide limited protection against infection but are effective in reducing severe illness.
Health / Covid-19
As of November 2025, COVID-19 remains a significant public health concern. This article summarizes key information about the virus, its transmission, and the latest research on Long COVID, also known as post-acute sequelae of SARS-CoV-2 inf...
### Transmission and Prevention COVID-19 spreads through infectious aerosols, behaving like smoke in the air. Preventing infection involves: - Wearing well-fitted N95 respirator masks in indoor settings. - Improving ventilation and using HEPA purifiers. - Getting vaccinated to reduce severe illness. - Using COVID tests before and after gatherings. - Staying home if sick.
### Long COVID Trajectories A Nature Communications study tracked 3,659 participants in the RECOVER Adult Cohort and identified eight distinct Long COVID profiles: - **Persistent, High Symptom Burden (5%):** Consistently met the criteria for Long COVID across all visits. - **Intermittently High Symptom Burden (12%):** Symptom burden fluctuated, intermittently meeting Long COVID criteria. - **Improving, Moderate Symptom Burden (10%):** Symptoms decreased over time. - **Improving, Low Symptom Burden (9%):** Symptoms decreased, mostly resolving by 6 months. - **Worsening, Moderate Symptom Burden (8%):** Symptoms gradually increased over time. - **Delayed Worsening Symptom Burden (6%):** Very low symptoms initially, increasing at 15 months. - **Consistent, Low Symptom Burden (13%):** Generally low symptoms with intermittent increases. - **Consistent, Minimal to No Symptom Burden (36%):** Never met the threshold for Long COVID.
### Why This Matters Understanding these trajectories is essential for clinical trials, patient care, and public health initiatives. Identifying different patterns helps target treatments and support for individuals with varying Long COVID experiences.
### How to Prepare - Reduce the risk of initial infection and reinfection by following preventive measures. - If infected, monitor symptoms and seek appropriate medical care. - Understand that Long COVID can manifest in diverse ways, and support is available for managing symptoms and improving quality of life.
### Who This Affects Most Long COVID can affect anyone who has been infected with SARS-CoV-2. The RECOVER study found that those with persistent, high symptom burden were more often female and had been hospitalized during acute infection.
Yes, current vaccines provide limited protection against infection but are effective in reducing severe illness.
Wearing N95 masks, improving ventilation, getting vaccinated, and staying home when sick are effective prevention measures.
There is currently no specific cure for Long COVID, but treatments can help manage symptoms and improve quality of life.
