Sentences

The researchers focused on the structure of the hemagglutinin protein to develop a more effective influenza vaccine.

Hemagglutinins play a critical role in the initial stages of viral infection by binding to host cell receptors.

The antibodies against hemagglutinins are key components in preventing the flu virus from infecting host cells.

Understanding the function of hemagglutinins is crucial for developing new antiviral medications.

Vaccines that elicit strong antibody responses against hemagglutinins can provide robust protection against influenza.

The presence of hemagglutinins in the influenza virus makes it capable of causing red blood cells to clump together.

The hemagglutinin sequence can vary between different influenza virus subtypes, leading to differences in viral strains.

Hemagglutinins are vital for the influenza virus to enter host cells, which is why they are targeted in vaccine development.

Nonhemagglutinating mutants of the influenza virus are less likely to spread owing to their inability to cause cell clumping.

Antibodies against hemagglutinins can neutralize the virus, preventing it from attaching to and infecting host cells.

The development of vaccines against hemagglutinins has greatly reduced the incidence of influenza outbreaks.

Hemagglutinins are important targets for antiviral drugs aimed at preventing viral entry into cells.

Influenza hemagglutinins change frequently, which is why annual flu shots are recommended.

The structure of hemagglutinins can provide insights into the mechanisms of viral entry and infection.

Antibodies against hemagglutinins can be detected in the blood of individuals who have been vaccinated or infected with the flu virus.

Researchers studying the hemagglutinin protein have identified potential sites for antiviral drugs.

Hemagglutinins are essential for the attachment of the influenza virus to host cells, making them important in viral replication.

The presence of hemagglutinins in the virus explains why influenza is so contagious.
