Vac means "empty", but I'm not sure how that would correlate to a vaccine.
It may though.
Rabies vaccine was invented by Louis Pasteur in 1885.
In 1955, a vaccine was developed that used weakened forms of the virus. This vaccine and the subsequent Sabin vaccine nearly wiped out polio in the world
If you don't have a vaccine in your body you are subjected to be quarantined when a pandemic disease spreads allover the world.
The smallpox vaccine comes from cows. Most diseases you a weakened form of the disease. However the smallpox vaccine is brought from cowpox. (closely related to smallpox but not as dangerous). You cannot get this vaccine anymore and if you did it would result in a bad reaction.
The time it takes to create a vaccine depends on how much is known about the antigen (or pathogen), how much testing is required and the way in which the vaccine is produces. New vaccines can be produces in as little as 8 - 10 months. Several countries come out with a new flu vaccine every year and people are advised to get immunized. If however, not much is known about the pathogen and human trials have to be carried out, it takes 3 - 7 years to come out with a vaccine that can go on the market. Vaccine manufacture has a huge amount of regulation and this factor adds to the time it takes for a vaccine to get on the shelf. Although a scientific breakthrough may come sooner than expected, clinical trials and product validation are long drawn processes that must not be surpassed.
Yes
vaccine was invented by Edward Jenner on May 14, 1796
It came from the latin Latin: vacinnus. and came from the word vaca meaning cow. vaccine was originaly made from cow pox to vaccinate against small pox.
It depends on the researcher, but if they find a cure for cancer or create an AIDS vaccine, that would be a dream come true.
yes DNA vaccine is a type of subunit vaccine and is also knwon as recombinant vaccine
In the 'developed' world, the MMR vaccine is readily available at your doctor's office. Most children would have already received it early in life.
In most of the world, the term "DT shot" referrs to a vaccination against diphtheria and tetanus. You will more likely likely come across a "DPT" or "DPaT" vaccine. These vaccines are aimed at diphtheria, tetanus, and pertussis. In the Netherlands, "DTP" refers to a combination vaccine against diphtheria, tetanus, and poliomyelitis (rather than pertussis).
