A 3 month old baby contracts a virus called whooping cough (pertussis) after receiving the first of a sequence of 3 necessary DPT vaccines designed to prevent 3 diseases (diphtheria, pertussis, and tetanus). The vaccines are given at 2, 4, and 6 months of age to allow the body to develop specific immunity against these diseases. After the infant recovered from the disease, the doctor informed the parents that from now on the infant would only need the DT (diphtheria, tetanus) part of the vaccine. Why does the infant only need the DT vaccine?
The infant had the first of a series of vaccines which caused the disease

Many times people visit the doctor requesting antibiotics to treat colds and viral infections. How is the doctor justified in offering the patient treatment options that do not include antibiotics for these cases?
Colds and viruses should be first treated with viral therapies and then when the body begins to recover, antibiotics can be used. Otherwise, the use of antibiotics is not effective at all.
Side effects from antibiotics are severe when used for colds and viruses. Any use of antibiotics for colds and viruses will only make the patient more ill and ultimately make the patient's recovery time longer.
Antibiotics can weaken the immune system when used for colds and viruses, whereas other medications are not so hard on the immune system during these types of illnesses.
If a doctor provides an antibiotic to treat colds and viruses, any bacteria in the patient's body will be killed, but a few will survive. Those few survivors may become resistant to antibiotics needed for real bacterial illnesses.
