Research suggests that too-frequent immunizations may lead to a phenomenon called “immune exhaustion.”
Evusheld is an antibody drug from AstraZeneca intended to help prevent COVID-19 infection for immunocompromised and other vulnerable patients.
Because COVID-19 is a relatively new virus, researchers still aren’t sure exactly how long vaccines and prior infections provide protection.
COVID-19 has taken away so much. An immunology researcher describes the good it may leave behind.
Some of the omicron variant’s unique properties – such as its ability to spread rapidly while causing milder COVID-19 infections – could usher in a new phase of the pandemic.
For a number of reasons, as time goes on vaccines become less effective. So how do researchers calculate how well vaccines are working?
Knowing when and how often to use rapid tests is key to getting an accurate picture of your COVID-19 status.
It’s too early to say whether the newly identified omicron variant is going to overtake delta. But particular mutations in the new strain have researchers deeply concerned.

The two types of COVID-19 tests – antigen and PCR – work in very different ways, which is why one is fast but less accurate and the other is slow and precise.
