Children in the United States are no longer vaccinated against smallpox, as that has been eliminated from earth, in the view of the WHO. Children in Europe are, or until recently were, still vaccinated against it. Polio was almost eradicated from earth, but vaccination programs got sloppy in some areas and it is now in a mild resurgence in some parts in the world.
Of course humans because we have vaccines and medicine.
This is how vaccines help the body's natural defenses against viruses: -because vaccines contain weak and dead viruses -this can help our immune system to recognize and adapt to it -so this will not be the problem for it if later on this type of viruses threat us Hope this help Vipha
Vaccines are available for disease-causing germs that remain the same. Â?Not all germs/viruses remain the same. Â?The 'flu virus changes or mutates millions of times a day. Â?It is because they are constantly changing that it isn't possible to make vaccines against many of them.
Because of the spleen's role in protecting people against infection, it should not be removed unless necessary. Splenectomies are performed in children only when the benefits outweigh the risks.
No, because: 1. Vaccines don't cure diseases, they prevent the person/dog from getting them in the first place, and 2. Vaccenes prevent against viruses, while heart worms are, well, worms. You can buy medication o give your do to prevent against worms, and to try and get rid of them, but there is no vaccine.
There are different kinds of triple antigen vaccines. A triple antigen vaccine is one made with three different antigens (often three virus strains). The seasonal flu vaccines are examples of triple antigen vaccines, because they contain vaccines against the three influenza viruses most prominent and most likely to spread that season. These are also called Triple Valent or Trivalent vaccines. Another example is the MMR trivalent vaccine made to vaccinate against Measles, Mumps, and Rubella. Several of the childhood vaccinations are this type of trivalent vaccine.
Yes, in fact many different vaccines exist for many different diseases (in the case of flu a new vaccine has to be made every year because the virus evolves so rapidly that the previous year's vaccine would not work against it).
why is diphtheria extremely rare in the united states today
because they protect you from disease
INFECTIONS
They are dangerous because they can kill you.
to make you healthy and also because people that do get vaccines have lower risks of death
