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!

A person is considered legally intoxicated in most states with a blood alcohol level of 80.0 mg/dl. calculate this concentration

Furkat [3]

The concentration expressed in parts per million is 782 ppm.

<h3>What is Parts per million?</h3>

It is calculated by dividing the mass of the solution by the mass of a solute present in one million (10⁶) parts.

<h3>Calculation for units in ppm:</h3>

Given:

Mass of blood alcohol = 80 mg/dL = 80 x $10^{5}$ g/mL

Density of blood plasma or Mass of blood plasma = 1.023 g/mL

Concentration in ppm = (Mass of alcohol/Mass of plasma) x $10^{6}$

= (80 x $10^{5}$ g/mL/ 1.023 g/mL) x $10^{6}$

= 782 ppm

Hence, the concentration expressed in parts per million is 782 ppm.
