What ethical considerations must be addressed when a new vaccine is being tested and released to the public?

Explanation:

Vaccines are tested in the laboratory before they’re recommended for use.This process can take several years.

During a clinical trial, a vaccine is tested on people who volunteer to get vaccinated. Clinical trials start with 20 to 100 volunteers.

Important things to consider when testing vaccines are

1) Is the vaccine safe?

-What dose (amount) works best?

-How does the immune system react to it?

2)The vaccine is tested in batches to make sure the vaccine is:

-Potent (does it work how it is supposed to)

-Pure (Certain ingredients used during production have been removed)

Sterile (It doesn’t have any outside germs)

3) Vaccines are monitored after they’re recommended to the public

Once a vaccine is licensed and recommended for use,the

vaccine continues to be monitored to ensure its safety.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
