The term variolation refers solely to inoculation with smallpox virus and
is not interchangeable with vaccination

because the latter was believed to cause occasional outbreaks of smallpox
. Vaccination, on the other hand, was less reliable.
What is the difference between vaccination and inoculation?
Vaccination: The act of introducing a vaccine into the body to produce immunity to a specific disease. Immunization: A process by which

What is the difference between smallpox inoculation and vaccination?
The difference between
antitoxins
and vaccines
Antitoxins are used as a treatment or cure when the infection is already present in the person. Vaccines, on the other hand, are examples of prophylactics – they prevent a disease from developing by stimulating the body’s immune system to produce antibodies in the blood.
What does the word variolation mean?

obsolete method of immunizing patients against smallpox by infecting them
with substance from the pustules of patients with a mild form of the disease (variola minor).
What are the 4 types of vaccines?
There are four categories of vaccines in clinical trials:
whole virus, protein subunit, viral vector and nucleic acid (RNA and DNA)
.
Why do we inoculate?
Inoculation may be defined as the process of adding effective bacteria to the host plant seed before planting. The purpose of inoculation is
to make sure that there is enough of the correct type of bacteria present in the soil so
that a successful legume-bacterial symbiosis is established.
When was inoculation banned?

What was the first vaccine?
Edward Jenner is considered the founder of vaccinology in the West in 1796, after he inoculated a 13 year-old-boy with vaccinia virus (cowpox), and demonstrated immunity to smallpox. In 1798, the first
smallpox vaccine
was developed.
Does smallpox still exist?

cowpox
to cure a human disease. Doctors were making money out of inoculations and did not want to lose that income. Vaccination was seen as dangerous – but this was because doctors often used infected needles.
How is inoculation done?
