The basic type of vaccines are:
nucleic acid vaccines
subunit vaccine
live, attenuated vaccine
An easy, secure, and reliable method of preventing hazardous infections before you are exposed to them is vaccination. It boosts your immune system and builds up your body's natural defenses against particular illnesses.
Your immune system is trained by vaccinations to produce antibodies, exactly as it does when it is exposed to a disease. However, because vaccinations only include dead or weakened versions of bacteria or viruses, they do not really cause the disease or increase your chance of developing its symptoms.
In order to create immunity, vaccines act in conjunction with your body's natural defenses. Your immune system reacts when you receive a vaccination.
