Because exposing your immune system to everything under the sun in one hit may be a bit too much for it to handle at once. If you want a good immune response, give vaccines over time - it's like you running three marathons at once: you're likely to perform better on them if they're not all in the one hit.
Some vaccines (flu vaccines) are different each year, depending on what strains are getting around.
Some vaccines are live - not dangerous, that bit's been bred out of them, but if you give these ones all together, they might ruin the chances of each of them actually having a response, because they might battle it out between each other.
depends on what country you go to
Dog vaccines normally offer protection from Distemper, Hepatitis, Parvovirus, Parainfluenza and Leptospirosis. Vaccines can also be given against Kennel Cough and Rabies.
It depends on which vaccine you are receiving.
Chickenpox vaccine is subcutaneous; it's given with a smaller needle than most vaccines.
Pulse Polio vaccines are given to children of 1-5 age.
People are given vaccines so that they are protected from certain illnesses.
No, vaccines are not injected into the skin. Most vaccines are administered through injection into the muscle or subcutaneous tissue (under the skin). Some vaccines are also given orally or nasally.
If the vaccines are supposed to be kept refrigerated until use, they are worthless if they are no longer cold.
Yes to protect them from getting sick!
so they dnt hav achance of gettin sick
It depends on the kind of vaccine. Injections of Flu vaccines can not be given to infants under 6 months old, as is true for many vaccines since an infant's immune system is not developed enough for a proper response to vaccinations until after 6 months. Nasal sprays containing attenuated flu virus vaccines can not be given to children under two. Ask your pediatrician what vaccines should be given and when.
21 vaccines before the age of six, and generally 6 more before the age of 18, for a total of 27 in childhood. Some vaccines are given multiple times (for example, the DTaP - diptheria, tetanus, and pertussis - is given 5 times).
