No more boosters - Researchers discover new antibody that kills all strains of covid

They hope to use it to create new vaccines against covid with broad effectiveness... it attaches to the spike protein (my non technical explanation).

SP1-77 is an antibody developed by researchers that so far can neutralize all forms of SARS-CoV-2, the virus that causes COVID-19. It was created after researchers modified a mouse model that was originally made to search for broadly neutralizing antibodies to HIV, which also mutates.

The mice used in the study have built-in human immune systems that mimic the way our immune systems develop better antibodies when we’re exposed to a pathogen. The researchers inserted two human gene segments into the mice, which then created a range of antibodies that humans might make. The mice were then exposed to SARS-CoV-2’s spike protein (which is what the virus uses to latch onto your cells) and produced nine different families of antibodies that bound to the spike protein to try to neutralize it.
