•COVID-19 vaccines & immune response
The COVID-19 vaccines are expected to provide at least some protection against new virus variants and are effective at preventing serious illness and death. That’s because these vaccines create a broad immune response, and any virus changes or mutations should not make vaccines completely ineffective. If any of these vaccines become less effective against one or more variants, it will be possible to change the composition of the vaccines to protect against these variants. Data continues to be collected and analyzed on new variants of the COVID-19 virus.
While we are learning more, we need to do everything possible to stop the spread of the virus in order to prevent mutations that may reduce the efficacy of existing vaccines. This means staying at least 1 meter away from others, covering a cough or sneeze in your elbow, frequently cleaning your hands, wearing a mask, and avoiding poorly ventilated rooms or opening a window.
