How do vaccines work? Do they work against viruses and bacteria? Why there<br> are so many vaccines.

Liono4ka [1.6K]

Answer:

Vaccines train our immune systems to create proteins that fight disease, known as ‘antibodies’, just as would happen when we are exposed to a disease but – crucially – vaccines work without making us sick. Live, attenuated vaccines fight viruses and bacteria. These vaccines

contain a version of the living virus or bacteria that has been weakened

so that it does not cause serious disease in people with healthy immune

systems. Because live, attenuated vaccines are the closest thing to a

natural infection, they are good teachers for the immune system.

Examples of live, attenuated vaccines include measles, mumps, and

rubella vaccine (MMR) and varicella (chickenpox) vaccine. Even

though they are very effective, not everyone can receive these vaccines.

Children with weakened immune systems—for example, those who are

undergoing chemotherapy—cannot get live vaccines. Those are only some vaccines, of course not all vaccines inject a live virus into your body. And of course, there are so many vaccines because (unfortunately) there are so many diseases!

Ksivusya [100]

Neisseria gonorrhoeae is treated with a combination of drugs because the organism is resistant to many, including penicillin and fluoroquinolones.

Gonorrhoeae is a contender to produce an incurable illness due to the development or acquisition of resistance mechanisms for sulfonamides, penicillins, tetracyclines, ciprofloxacin, and more recently azithromycin and ceftriaxone during the past 80 years.

The Neisseria gonorrhoeae bacteria is the source of the sexually transmitted illness (STD) known as gonorrhea. The urethra in both men and women as well as the cervix, uterus, and fallopian tubes in women are all affected by N. gonorrhoeae infection.

Penicillin is the first drug that has been shown to be effective against syphilis and gonorrhea. However, compared to the dosage required to treat syphilis, which is often approximately 1,000,000 units, the drug used to treat gonorrhea is frequently administered in doses of just around 100,000 units.
