The most critical thing we can do to safeguard ourselves and our children against illness is to be vaccinated. Every year, they save up to 3 million lives worldwide.
The majority of teenagers in India can be protected against several deadly diseases that used to kill millions of people annually by immunising them against such diseases.
Your immune system learns from vaccinations how to produce antibodies that shield you from disease. Your immune system will learn this lesson much more safely through immunization than by contracting the illnesses and undergoing treatment.
Once your immune system is trained to combat a disease, it can frequently keep you healthy for years.
A person is left exposed and still at danger of contracting a disease if they do not receive the entire course of a vaccine. For other immunizations, a booster shot is required once every year to maintain a high degree of immunity.
