Which happens more often group of answer choices a pathogen evolves vaccine resistance a pathogen evolves drug resistance?

These two factors synergistically slow the evolution of resistance to vaccines (6). Thus, one reason why the evolution of drug resistance is more problematic than the evolution of vaccine resistance is that drug resistance is more likely to evolve.

Can virus become resistant?

A resistance mutation is a mutation in a virus gene that allows the virus to become resistant to treatment with a particular antiviral drug. The term was first used in the management of HIV, the first virus in which genome sequencing was routinely used to look for drug resistance.

What diseases don’t have a vaccine?

• Chagas disease (American trypanosomiasis)
• Chikungunya.

• Cytomegalovirus.
• HIV/AIDS.
• Hookworm infection.
• Leishmaniasis.
• Malaria.

Why is it so difficult to discover new antibiotics?

The antibiotics that have been brought to market in the past three decades are variations of drugs that have been discovered before. Discovering and developing genuinely new antibiotics is challenging: the science is tricky and the research and development process is time-consuming and expensive, and often fails.

How do bacteria evolve?

Experimental evolution of resistance to ciprofloxacin (CIP) in liquid-grown and biofilm-grown bacteria. Samples of bacteria were collected from each culture at various times during the experiment and also at the end of the experiment.

Do vaccines cause antibiotic resistance?

While antibiotic development is declining, vaccine technology is growing. This review shows how vaccines can decrease AMR by preventing bacterial and viral infections, thereby reducing the use/misuse of antibiotics, and by preventing antibiotic-resistant infections. Vaccines are less likely to induce resistance.

How does influenza become resistant?

Typically, flu virus is called resistant after sufficient evidence was gathered to prove a lack of antiviral effect of a particular antiviral medication in patients infected with such virus. In the United States, there are four FDA-approved antiviral drugs recommended by CDC this season.
