Edward Jenner succeeded in creating a vaccine against smallpox by injecting patients with material of which disease?
Smallpox
Cowpox
Cattle virus
What is the function of innate immune response?
Act very rapid as a first line of defense to eliminate the infection
Trap microbes so they cannot spread in our body freely
Coordinate and support adaptive immunity
What is the main advantage of live attenuated vaccine?
It provides more durable immunity; boosters may be required, though less frequently than would otherwise be necessary
It is safer than other kinds of vaccines
It does not cause any severe side effects or complications
Which is not true about subunit vaccines?
They can be designed using molecular biology technique
They are less harmful than live attenuated vaccine
They provide lifetime protection
Since we have our immune system to protect us from disease, why do we still need a vaccine?
Because adaptive immunity takes days to weeks to initiate a response and sometimes it is too late
Because some people are immune deficient or have weak immune systems
All of the above
