Question

Entire dead cellular pathogeno or whole inactivate virus and an examples are polio and hepatitis vaccines

purified subunit vaccine

live attenuated vaccine

subunit vaccine

whole-agent vaccine

Answer 1

Inactivated vaccines use the killed version of the germ that causes a disease. Inactivated vaccines usually don’t provide immunity that’s as strong as live vaccines. So you may need several doses over time (booster shots) in order to get ongoing immunity against diseases.Inactivated vaccines are used to protect against:

• Hepatitis A
• Polio (shot only)

while, for other options:

SUBUNIT VACCINES: These vaccines use only specific pieces of the germ, they give a very strong immune response that’s targeted to key parts of the germ. They can also be used on almost everyone who needs them, including people with weakened immune systems and long-term health problems.

LIVE-ATTENUATED VACCINES:Live vaccines use a weakened (or attenuated) form of the germ that causes a disease.Because these vaccines are so similar to the natural infection that they help prevent, they create a strong and long-lasting immune response. Just 1 or 2 doses of most live vaccines can give you a lifetime of protection against a germ and the disease.But live vaccines also have some limitations:

• Because they contain a small amount of the weakened live virus, some people should talk to their health care provider before receiving them, such as people with weakened immune systems, long-term health problems, or people who’ve had an organ transplant.
• They need to be kept cool, so they don’t travel well. That means they can’t be used in countries with limited access to refrigerators.
