• live attenuated

• inactivated

• toxoid

• conjugate

Which type of vaccine is the COVID 19 vaccine?

• live attenuated

• conjugate/recombinant

• toxoid

• inactivated

What is the correct order of the chain of infection?

• susceptible host, port of exit , port of entry, agent, reservoir, mode of transfer

• agent, reservoir, port of exit, mode of transfer, port of entry, susceptible host

• port of exit, mode of transfer, port of entry, susceptible host, agent, reservoir

In the chain of infection, this is the host or environment in which the pathogen can live.

• agent

• port of exit

• susceptible host

• reservoir

Ways in which pathogen leaves the host.

• port of entry

• reservoir

• port of exit
