Covid-19 Vaccine Designed to Prevent Disease, Says Moderna CEO

The transcript discusses the initial human trials of a vaccine, focusing on safety and the presence of neutralizing antibodies. It explains how the immune system responds to viruses and the importance of preventing disease through vaccination. The primary goal is to prevent disease, with infection prevention as a secondary objective.

What was observed in the initial group of 8 humans who received the vaccine?

• They experienced severe side effects.

• They showed signs of disease.

• They had no antibodies.

• They were doing well with no major issues.

What is the role of neutralizing antibodies in the context of vaccination?

• To replicate the virus faster.

• To cause side effects in the body.

• To bind and neutralize the virus, preventing replication.

• To increase the viral load in the body.

How does the body respond to a natural infection according to the video?

• It creates a few copies of the virus.

• It uses the virus to strengthen the immune system.

• It educates the immune system to produce neutralizing antibodies.

• It ignores the virus completely.

What is the primary goal of the vaccine as discussed in the video?

• To ensure no side effects occur.

• To prevent infection at all costs.

• To increase the viral load for better immunity.

• To prevent disease, even if infection occurs.

What is considered a secondary endpoint in the phase three trials?

• Prevention of infection.

• Increase in antibody production.

• Reduction of side effects.

• Complete eradication of the virus.
