Futurism: When should you take an at-home COVID test?

COVID-19 vaccines and boosters are hugely valuable. In addition to providing protection from the virus, vaccines and boosters reduce the chances of serious illness, hospitalization, and death. But people can still get infected when they’re fully vaccinated and boosted. This may be because the vaccine’s protection has decreased over time or because a new variant (like the Omicron variant) is better at getting around the vaccine’s protective properties.

COVID-19 infections in fully vaccinated people are called breakthrough infections, which usually result in milder symptoms versus infections in the unvaccinated. Your body’s memory B cells and T cells, which developed after your vaccine, respond quickly to stop the infection and prevent severe damage.

Immunocompromised people may not have strong B cell- and T cell-immunity even after vaccination, so they remain at higher risk. If you are immunocompromised and have a breakthrough infection, you should contact your doctor even if you only have mild symptoms.

Unvaccinated people don’t have existing antibodies or memory B cells or T cells waiting to fight off COVID-19, so they have to start their immune response from scratch if they become infected. Infections typically cause more damage to their organs and tissues, which can lead to complications like having low oxygen levels, as well as problems with the lungs, kidney, and heart. Unvaccinated individuals are also much more likely to need intensive care support or have lingering symptoms known as long COVID-19.
