Vaccines do not prevent infection. Vaccines prepare the immune system to fight infection by allowing the immune system to produce antibodies to a specific invading organism, kill it, and remember it in the future. In vaccines, this organism is often weakened or dead. If the invading organism is found by the immune system in the future following immunization, the immune system remembers it and produces the specific antibodies needed to kill it quickly.
Vaccines are for preventing infections. Infections are pathogenic (caused by germs). Vaccines help your body prepare to fight specific pathogens, e.g., bacteria and viruses.
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
true
You can purchase vaccines at animal supply stores and administer them yourself. Vaccines require storage in specific temperatures/conditions. To be sure they are as effective as possible, the vet is best.
Yes. True
Edible vaccines are vaccines produced in plants genetically modified through bioengineering.
We need vaccines to protect us from infectious diseases and to trigger the immune system to respond with production of antibodies made for that specific pathogen. See the related questions for more details of how this works.
Vaccines do not cause AIDS.
No there is one flu vaccine for under age 65 and one for over age 65.
Conventional vaccines consist of whole pathogenic organisms, which may either be killed or live vaccines; the virulence of pathogens is greatly reduced in attenuated vaccines. This is classified into 2 categories :a)Live or attenuated vaccines; (eg : BCG vaccine)b)Inactivated vaccines (eg : Salk polio & Pertussisvaccines)
