Complete the following paragraph to describe the future of influenza vaccines. Progress is being made in developing a (Click to select) vaccine that would provide (Click to select) protection for individuals. Instead of focusing on the genes that code for the (Click to select) evolving H and N spikes, newer vaccines are targeting other proteins within the (Click to select) . The proteins, called (Click to select) , (Click to select) at the same rate as the H and N spikes on the virus. By using these proteins as (Click to select) as the basis for vaccines to trigger an (Click to select) immune response, scientists are able to provide protection against a variety of influenza viruses since the core proteins are more similar between influenza viruses than the spikes.
