What is the difference between live and attenuated vaccines

[strawberry]

I'm really confused about the difference between live and attenuated vaccines and I'm hoping someone can help me out. Can someone explain the difference between the two and why each type of vaccine is used? I'd really appreciate any information or advice about this topic.

Live vaccines use weakened forms of the virus or bacteria, while attenuated vaccines use dead forms of the virus or bacteria.

Live Vaccines

Live vaccines are made from live, but weakened forms of the virus or bacteria that causes the disease. Live vaccines are usually more effective than attenuated vaccines, as the weakened virus or bacteria can still replicate in the body, providing a longer-term immunity.

Examples of live vaccines include the measles, mumps, rubella, varicella (chickenpox), rotavirus, and yellow fever vaccines.

Attenuated Vaccines

Attenuated vaccines, also called inactivated vaccines, use dead forms of the virus or bacteria. Because the virus or bacteria cannot replicate in the body, these vaccines usually require booster shots to maintain immunity.

Examples of attenuated vaccines include the inactivated polio, influenza, and hepatitis A vaccines.

Live vaccines contain a weakened form of the virus, which is not strong enough to cause disease. Attenuated vaccines contain a dead or inactivated form of the virus. Live vaccines are more effective at providing long-term immunity to the virus, while attenuated vaccines are not as effective. However, live vaccines can cause mild side effects in certain individuals, while attenuated vaccines are generally safe.

Live vaccines are made from weakened forms of the same virus or bacteria that causes a particular disease. These weakened forms are not strong enough to cause serious illness, but they can still stimulate the body's immune system to produce antibodies to the disease. Attenuated vaccines are made from killed forms of the virus or bacteria and are not able to cause the disease. However, they can still generate an immune response to protect against future infection with the disease.

Live vaccines contain a weakened version of the virus or bacteria they are meant to prevent. These vaccines are designed to stimulate the body’s immune system without causing the full-blown symptoms of the disease. This type of vaccine is very effective at preventing infection and is usually administered in a single dose. Examples of live vaccines include the measles, mumps, rubella (MMR), rotavirus, and varicella (chickenpox) vaccines.

Attenuated vaccines, on the other hand, contain a weakened form of the virus or bacteria but still contain some of its active components. These vaccines typically require multiple doses. Attenuated vaccines can be effective at preventing infection, but they may not provide complete protection. Examples of attenuated vaccines include the yellow fever and typhoid vaccines.

The main difference between the two is that live vaccines contain a weakened version of the virus or bacteria, while attenuated vaccines still contain some of its active components. Live vaccines are generally more effective at preventing infection than attenuated vaccines, but attenuated vaccines may be more effective at inducing long-term immunity. Additionally, live vaccines often require only one dose, while attenuated vaccines require multiple doses.

Live and attenuated vaccines are both forms of immunization that are used to protect against infectious diseases. Live vaccines contain weakened versions of the virus or bacteria that cause the disease, while attenuated vaccines contain killed versions. Live vaccines are more effective in protecting against disease, as they act as a "simulated infection" and create a stronger immune response. Attenuated vaccines are more appropriate for those with weakened immune systems, as they do not produce the same level of immunity. Live vaccines may also have a longer lasting protection, as they can produce memory cells that remain in the body for longer and can respond to future infections.
