Vaccinations, also known as immunizations play a vital role in protecting children and adults from diseases. There are two types of vaccines – live and inactive virus vaccines. The live virus uses tiny amounts of weakened bacteria or viruses that cause disease to stimulate the immune system.
The inactive virus contains the killed virus which produces antibodies that attacks the virus and prevents the infection. Getting vaccinated can actually save your life – it might not prevent disease completely but helps lessens the symptoms.
