difference between vaccines and drugs

Hello, I'd like to introduce the difference between vaccines and therapeutic agents today.

Recently, I think there are many people who are concerned about the difference between vaccines and therapeutic agents due to specific diseases.

Of course, many of you may know this, but I've posted about why it's so difficult to develop vaccines and therapeutic agents, so please enjoy it.

 

Vaccines are drugs used in preventive activities to make humans and animals immune to specific viruses.

In other words, it is not a medicine for treatment, but a preventive medicine. If you're already sick, getting vaccinated may not cure the disease, but it may get worse. Vaccines form antibodies by administering weakened or incapacitated antigen information to the body so that the immune system recognizes them.

Have you heard of herd immunity? In population immunity, if there are more than a certain percentage of antibody holders in a population, the probability of infection of the virus among its members will decrease dramatically, and the disease caused by the virus will end.

 

Smallpox is a prime example of vaccine eradication.There is a high risk of smallpox in Korea, too. They were vaccinated around the 1970s. More than a decade later, newborns don't get smallpox even if they don't.
Smallpox can be said to eradicate human herd immunity.

The most fundamental principle of vaccines is to cultivate the antigens that cause the above-mentioned diseases and infectious diseases, and then inject them into the dead or just before death. Today, with the development of science, vaccines are gradually being developed, and various forms of vaccines have appeared.

vaccine side effect

However, vaccines can have side effects. Therefore, it will be put on the market after one phase, two phases and three phases through animal experiments.

The verification period for these side effects delays the release of vaccines and drugs.

So, what are the side effects of vaccines?

There are people who have allergic reactions to vaccines. Egg ingredients often enter the culture solution in the process of culturing antigens, but people with severe egg allergies may experience allergic reactions. However, in the case of recent vaccines, we manufacture vaccines without egg ingredients except in cases where they have to be mass-produced in a short period of time like influenza vaccines, but the disadvantage is that the unit price is high.
The therapeutic agent is a substance that can be treated when infected with a virus.
Antibody drugs, antiviral drugs, antibiotics, and so on, which have recently appeared, are the therapeutic agents.

In the case of vaccines, vaccine substances are used to prevent viruses, and therapeutic agents are substances used to treat viruses.

The global disease needs medicines for those who have already been infected, and the world is in great demand to provide vaccines for herd immunity.

This concludes the posting of the difference between vaccines and therapeutic agents.
