is the childhood shots the same as for the childern in 1920,1950? are are they different? name them please?

Answer 1

Yes they are different. New vaccines have been developed over the ears.

There are too many to answer in list form here. However, check out the website below. The site has pdf files of the immunization schedules for different age groups.

Answer 2

Some of the first injections for children were really antisera, that is, serum to counter a specific disease. It was produced by injecting an animal, usually a horse, with a specific bacteria, then recovering the serum after the animal recovered. It contained antibodies against the disease. Emil Behring won the Nobel Prize in the early 1900's and became von Behring for this technique.

Some true toxoids came out in the 1930's, for tetanus and diphtheria. Pertussis vaccine followed. Polio vaccine came out about 1954, oral polio vaccine several years later. Measles vaccine came about around 1964, followed by rubella and mumps several years later. Currently there are vaccines against Haemophilus influenzae, chicken pox, hepatitis A and B, meningococcus, several strains of S. pneumoniae, and the list goes on, eg, vaccine against HPV that causes cervical cancer. And of course, the annual flu shot. In the course of time, some of the older vaccines have been improved to enhance immunity and/or to reduce adverse side effects.

Answer 3

Think 1957. People born before that year expected to have measles, German measles, mumps, and chicken pox. The smallpox vaccine is somewhat older, but most of the immunizations now routine were not available to people in the 50's. I remember standing in line at the high school gym to get my sugar cube when the oral polio immunization became available.
Hemophilus influenzae B, hepatitis B, varicella, pneumococcal vaccine, and others are quite a bit more recent still, many coming into use in the 80's.
