Oxford vaccine reduces transmission of Covid-19, study suggests

The video discusses the importance of reducing infection rates to lower transmission risks in the population. It highlights that if individuals do not get infected, they cannot spread the virus, thus decreasing overall transmission. However, it also warns that the virus is evolving to produce new variants that can bypass immunity from previous infections or vaccinations, allowing it to continue spreading.

What is the primary benefit of reducing the chances of infection in a population?

• It makes the virus stronger.

• It has no effect on transmission.

• It decreases the risk of transmission.

• It increases the number of infections.

How does reducing infection affect the ability to pass on the virus?

• It increases the ability to pass on the virus.

• It has no effect on transmission.

• It prevents the virus from being passed on.

• It makes the virus more contagious.

What is a significant challenge posed by new virus variants?

• They do not affect transmission.

• They are easier to detect.

• They can avoid existing immunity.

• They are less contagious.

Why is it important to be cautious about new virus variants?

• They can still transmit despite immunity.

• They are less harmful.

• They are easier to treat.

• They do not change over time.

What does the virus attempt to do as it produces new variants?

• It tries to avoid being transmitted.

• It tries to become more visible.

• It tries to avoid existing immunity.

• It tries to become less contagious.
