Vaccines use a different mechanism than that of drugs to fight off pathogens.

Drug resistance kills the bacteria themselves. Vaccines prepare your body to resist pathogens. Horizontal gene transfer

Vaccine resistance is less common than drug resistance because vaccines target many parts of a pathogen at once and prevent replication early, while drugs usually target a single mechanism after infection has already begun.

It would be harder for a virus to become resistant against one's immune system compared to a bacteria evolving to resist antibiotics.

Antibiotics work by targeting the bacteria directly in a one-on-one battle. Vaccines help harness your entire immune system instead.

Vaccine resistance is less common than drug resistance because vaccines target the overall body while drugs have a specific target within the body to fight off diseases.

Vaccines are given prior to high pathogen abundance, whereas drugs are usually given after pathogen has become abundant and, in tandem, more likely to become resistant.

Vaccines train the immune system to combat a certain disease in a multitude of ways, while antibiotics (drugs) target whatever disease it may be in a very specific way

Bacteria could possibly mutate at a higher rate, they also can do horizontal gene transfer. Viruses don't have DNA which could be a reason why they are not as capable of resistance compared to bacteria. Vaccines are preventative and antibiotics are in response to already present infection

Vaccine resistance is less common than drug resistance because vaccines prevent the virus from infecting people in the first place so it can't replicate as much and mutate, while drugs target an already replicating pathogen that has more possibility to mutate and become resistant.

Team 34

2026-04-30 19:12:33 UTC

Vaccine resistance is less common than drug resistance because vaccines prevent replication before the pathogen has the chance to infect hosts.

Team 37

2026-04-30 19:12:49 UTC

vaccine resistance typically present multiple targets to the immune system, making it harder for pathogens to evolve simultaneously.

Group 33

Drug resistance is developed by the organisms themselves, whereas vaccines fight drugs by helping individuals build immunity. On a herd level, vaccines help foster herd immunity, limiting the spread of the pathogen and therefore the number of chances it has to develop a resistance.

Viruses require hosts to replicate. Vaccines cause an immune response while antibiotics directly kill the organisms.

Vaccines allow for better long term adaptive immunity while drug resistance does not.

28

2026-04-30 19:13:52 UTC

Vaccines work as it's your body doing the resistance, whereas drug resistance fails as it targets a specific pathogen, allowing it to become resistant.

COVID-19 is dangerous because it causes severe immune responses, damages multiple organs, and spreads easily. It is particularly deadly to older adults and those with pre-existing conditions, leading to severe respiratory failure.

28

COVID was able to spread a lot while also being very virulent. So, it didn't need to be adjust to be less virulent to spread and could remain harmful

Team 38

2026-04-30 19:52:12 UTC

There was intermediate virulence, allowing the host to present more opportunities for transmission. Period of latency is relatively short compared to the period of transmission. Infectiousness decrease allowing for shorter survival

Group 39

Covid had a really high transmission between hosts, so it can have a high virulence since it isn’t prioritizing replication within the host.

COVID is so harmful because it has high infectiousness before it becomes fatal. A patient would be able to infect alot of people before symptoms and death occur.

Team 41

2026-04-30 19:52:25 UTC

It spread really fast and had high mutation rate and kept evolving

Team 27

2026-04-30 19:53:01 UTC

Because our natural defenses were not familiar with the strain.

Team 34

COVID-19 is very harmful because it can reproduce very quickly while maintaining its high virulence, unlike other diseases.

Team 29

2026-04-30 19:53:05 UTC

COVID-19 came from a different species, likely a bat that infected a raccoon dog. Since it crossed over from a different species, it didn't adapt to the correct virulence for human so it was more deadly. Also, it has a polybasic cleavage site which increases the virulence.

Group 31

2026-04-30 19:53:26 UTC

COVID was so harmful because it's very infectious within the first few days of infection so it spreads very fast.

36

2026-04-30 19:53:30 UTC

Potentially covid had a longer span of infectiousness before death occurs in the host. Also, maybe it reproduces a lot before it causes death, meaning it can be highly virulent. However, virulence is not a tradeoff for covid because it is most infectious before the host dies, meaning high transmission as well.

Team 40

2026-04-30 19:53:40 UTC

Covid-19 was so harmful because infectiousness period occurred before patients death so it increases the likelihood of covid transmission

Team 35

2026-04-30 19:53:55 UTC

COVID is most fatal past its period of highest transmission. Fatality isnt selected against at this 2 week point because the host is already not infectious.

Group 33

2026-04-30 19:53:56 UTC

Covid-19 has a perfect virulence - high enough to cause harm in susceptible individuals but not so high that it kills the host before it has the chance to spread.

Team 30

2026-04-30 19:54:06 UTC

Because death occurs significantly after the latency infectious period, the virus can be very harmful and virulent and still have high transmission.
