Viruses Flashcards
What’s the function of Capsids?
A protein “container” that stores viral genes.
What’s the function of Glycoprotein?
Proteins on the surface of the virus that help it locate the target or host cell.
What’s the function of viral genes?
Viral genes allow the virus to do the following:
-Recognize target/host cells
-Insert viral genes into the host cell
-Force the host cell to produce more viruses
-Cause the host cell to undergo lysis (bursting open) so that viruses are free to infect other host cells nearby
If I was vaccinated against chickenpox as a child, should I get the shingles vaccine when I’m older?
Yes
If I had chickenpox as a child, should I get the shingles vaccine?
-Yes, because the varivax vaccine is offered for younger people, and shingles is offered for when older in life
What happens if I’ve never been exposed to chickenpox and haven’t been vaccinated against chickenpox, but being around someone who has shingles?
You will have no infection if you have had no direct contact with the blisters
If I get the chickenpox vaccine, could I still get chickenpox? Likewise, if I get the shingles vaccine, could I still get shingles?
Varivax is 70-90% effective while Shringrix is 95% effective
If chickenpox and shingles are caused by the same virus, then why are two different vaccines given? For example, the Varivax vaccine offers protection against chickenpox while the Shingrix vaccine offers protection against Shingles.
The vaccines are for different types of people
What’s the cause of Chickenpox?
“varicella” part of the virus
What’s the cause of Shingles?
“zoster” part of the virus
What’s the prevention for Chickenpox?
A live, intact vaccine known as the Varivax vaccine (2 doses) which creates a stronger immune response
When does Chickenpox appear in life?
Childhood
What are the routes of transmission for Chickenpox?
By direct contact with blisters or through coughing and sneezing because it lies in saliva
What’s the prevention for Shingles?
A subunit vaccine is known as the Shingrix vaccine (2 doses) which creates a weaker immune response because of tiny particles broken apart (protect against shingles)
When does Shingles appear in life?
Older Adults (50 or higher cuz of weaker immune system)—> 1 in 3 people get this virus in their lifetime
