The ribonucleotide analogue remdesivir (red) inhibits  the coronavirus replication by blocking the RNA synthesis in the viral RNA dependent RNA polymerase (RdRp, blue).  Four  remdesivir molecules have already been attached to the growing RNA chain. Another remdesivir molecule is entering the active site of the RdRp. Source: PDB entry 7l1f.
A ribbons model of an antibody, also known as immunoglobin. The immune system produces antibodies (using white blood cells) which then identify and attack viruses and bacteria.
