A stem cell is a type with a capacity to produce other cells that develop into any form. There is an ongoing debate questioning the need to continue with embryonic stem cell research or adult stem cells work just as well. Such a discussion should create an interest to understand the composure and capabilities of both. Embryonic stem cells are got from embryos thus generating a lot of ethical controversy and discussion.

Embryonic stem cells are unspecialized cells with the ability to:

Stem cells are body cells that can divide and differentiate. Stem cells specialize as an organism grows to take specific functions. For instance, these mature tissues all have a different type of cells.

Stem cells are the natural reservoir of the body that replenishes specialized cells after use ordamage. Stem cells are at always at work inside the bone marrow inside us making the 100,000 new blood cells that we need each day. The body needs new cells all the time to keep functioning, but some of those that are specialized like muscle or blood cells cannot make copies through cell division. They instead rely on populations of stem cells for replenishment. Stem cells have a unique ability to produce their copies (self-renewal) and other speculated cells (differentiation) each time they divide.

Stem cells might turn to any type before they differentiate into these types.

The World Health Organization (WHO) makes a gamble every year when developing a flu virus. They try to determine the flu viruses that will dominate. WHO vaccine makers get two chances one for each hemisphere, but effectiveness only reaches a certain per cent such as 10% in Australia.

A vaccine that is 10 per cent effective does not mean that it is also 90 per cent useless. A percentage shows the extent to which a shot reduces the risk of getting a disease but is not a reflection of how much it can help to ward off the extremely severe symptoms. A mismatched vaccine still gives an advantage when the body faces an influenza virus, but it makes it crucial for everyone to receive a shot. Highly effective vaccinations are necessary because inoculated persons are unlikely to contract flu thus the number of those who require it will be lower.

A Better Way of Making an Effective Flu Vaccine

Animal cell-based vaccine

The cell-based vaccine is still a new method that provides an alternative to develop a flu vaccine in the egg. People who are allergic to eggs get a different shot that grows in animal cells instead of an egg, and it does seem to get problematic mutations.
