The antibodies we create after we're infected with a virus or vaccinated against it can be very powerful. A virus typically spreads within our bodies by entering a cell and using it as a factory to create copies of itself, which then burst out and find new cells to infect. Our antibodies work by binding to the virus and this can block it from attaching to and entering our cells in the first place.
But what happens if a virus does not need to exit the cell in order to spread to neighboring cells? Can our antibodies be effective against it?
Scientists recently asked this question for SARS-CoV-2, which causes COVID-19. This highly infectious coronavirus can change human cells, making them fuse with two or more nearby cells. These super-cells, with large merged cell bodies, are excellent viral factories.
I know having the vaccines doesn't stop you getting Covid unfortunately but hopefully not with serious consequences. My friend and her husband, both twice vaccinated, have contracted it possibly from their daughter. Her husband is on the verge of hospitalisation. Very worrying.
Hopefully those Lymphocytes, B-cells and T-cells are going to get to work, unfortunately it does take a little time for them to start working, this is possibly why people can still get infected but not become seriously ill. Fingers crossed for both of them.
