Immunization is a global health and development success story, saving millions of lives every year. Vaccines reduce risks of getting a disease by working with your body’s natural defences to build protection. When you get a vaccine, your immune system responds. However, in the foreseeable future it is important that we adopt the lifestyle of wearing masks, cleaning hands, ensuring good ventilation indoors, physical distancing, and avoiding crowds.
Vaccination protects the vaccinated persons and those around them who are vulnerable, reducing the risk of transmission among family members, school mates or colleagues, friends, neighbours and other people in the community. Vaccination of one person indirectly protect others. Furthermore, heath or of similar nature programmes help reduce the social, psychological and financial burdens caused on people and governments, reducing pressures on healthcare and social care systems and enabling people to pursue productive activities including education and employment.
