I am still curious about how someone become qualified to create vaccines

# data[].attributes.body
It is still unclear why it takes so long to create a vaccine

# data[].attributes.body
It was surprising to me that under normal circumstances, vaccines take about 5-10 years to create. The covid vaccine was created so quickly because scientists were not starting from scratch. It is very similar to SARS, which scientists have been studying for years.

Vaccines

Vaccines are usually used to combat viruses, but antibiotics are usually used to combat bacteria. The differences with these are that antibiotics are not always in a vaccine form.

I learned that the main reason why some vaccines are more effective than others is because of their ingredients.

-antibodies
-parts of pathogens
-adjuvants (wake up the immune system)

Vaccines help the body create antibodies, which in collaboration with immune cells called phagocytes, destroy pathogens.

The part ot the immune system that vaccines train is the adaptive immune system.

Vaccines train our immune system to detect and attack pathogens that enter our bodies. This can be connected to what we previously learned about the smallpox vaccine
