What we need to know about vaccines?
Vaccines have greatly reduced infectious diseases that once regularly harmed or killed many infants, children, and adults. However, the germs that cause vaccine-preventable disease still exist and can be spread to people who are not protected by vaccines.
What are the characteristics of a good vaccine?
1. The major requirements of the vaccine. This includes primarlly safety and efficacy and a number of other desirable features if the vaccine is to control a disease of global importance. These include cost, easy administration (e.g. orally), thermal stability, multivalency and long-lived immunlty 2.

What is a vaccine simple definition?
ANSWER. A vaccine is a substance that helps protect against certain diseases. Vaccines contain a dead or weakened version of a microbe. It helps your immune system recognize and destroy the living microbe during a future infection.
What are vaccines used for?
Vaccines are used to boost your immune system and prevent serious, life-threatening diseases.
What are vaccines short answer?
A vaccine is a type of medicine that trains the body’s immune system so that it can fight a disease it has not come into contact with before. Vaccines are designed to prevent disease, rather than treat a disease once you have caught it.
How many vaccines do you need?
Catch-up vaccination Unvaccinated persons through 18 years should complete a 2-dose series (minimum interval: 6 months). Persons who previously received 1 dose at age 12 months or older should receive dose 2 at least 6 months after dose 1.
What are the 5 types of vaccines?
As mentioned earlier, there are five main types of vaccines: attenuated (live) vaccines, inactivated vaccines, toxoid vaccines, subunit vaccines, and conjugate vaccines.
What are the two major types of immunization?
There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used. Live attenuated vaccines are produced by modifying a disease-producing (“wild”) virus or bacterium in a laboratory.
How many vaccines do babies get?
Currently, 16 vaccines – some requiring multiple doses at specific ages and times – are recommended from birth to 18 years old. Recommended vaccines include: Influenza (annual flu shot) Diphtheria, tetanus and pertussis (DTaP)
How is a vaccine made?
Vaccines are made by taking viruses or bacteria and weakening them so that they can’t reproduce (or replicate) themselves very well or so that they can’t replicate at all. Children given vaccines are exposed to enough of the virus or bacteria to develop immunity, but not enough to make them sick.
How are viruses killed for vaccines?
The virus is killed using a method such as heat or formaldehyde. Inactivated vaccines are further classified depending on the method used to inactivate the virus. Whole virus vaccines use the entire virus particle, fully destroyed using heat, chemicals, or radiation.
Who make vaccines?
Pfizer has been involved in the development of vaccinations since the early 1900s when it created the first heat-stable, freeze-dried smallpox vaccine. The company was also the first to develop a combined diphtheria, pertussis and tetanus vaccination.

Is mercury still used in vaccines?
This mercury-containing ingredient has been used as a preservative in vaccines since the 1930s. Today, it is only found in vaccines for influenza. Preservatives are necessary for preventing dangerous bacterial or fungal contamination, but thimerosal has since become a major source of vaccine safety concerns.
What chemicals are in the flu shot?
Here are some ingredients you’ll find in the flu shot:Egg protein. Many flu vaccines are made by growing the viruses inside fertilized chicken eggs. Preservatives. Vaccine manufacturers add the preservative thimerosal to multidose vaccine vials. Stabilizers. Antibiotics. Polysorbate 80. Formaldehyde.
