Could we Have Universal Flu Vaccine?

The video discusses recent advancements in flu vaccine research, highlighting the challenges posed by the constantly mutating HA protein. A new study targets the more stable HA stock, showing promise in early trials. Additionally, a separate study on bacterial mutations reveals RNA thermosensors' role in disease progression, offering potential for new diagnostic methods.

Why do flu vaccines need to be updated every year?

• The flu virus is only active in certain seasons.

• The flu virus is resistant to all vaccines.

• The flu virus has a stable structure.

• The flu virus has many variants that change constantly.

What is the main target of current flu vaccines?

• The virus's DNA

• The virus's RNA

• The HA protein on the virus

• The virus's lipid membrane

What was the outcome of the phase one trial for the new flu vaccine?

• It was safe and produced a strong immune response.

• It was unsafe but effective.

• It was safe but ineffective.

• It was unsafe and ineffective.

What is the limitation of the new flu vaccine discussed in the trial?

• It is not effective in humans.

• It causes severe side effects.

• It is effective against all flu strains.

• It only works against Group One HA proteins.

What role do RNA thermosensors play in Nyceria meningitidis bacteria?

• They help the bacteria reproduce faster.

• They alter cellular activity in response to temperature.

• They convert DNA into proteins.

• They help the bacteria produce energy.
