Natural Immunity Versus Vaccines
Simple fact: The basic purpose of any vaccine is to help the body to develop antibodies that improve the immunity to fight the virus.
Human body, the best machinery on this earth, has an inbuilt mechanism to cure itself when a foreign body enters. When the body gets infected with a new germ, it activates fighting tools (called cells) to fight. This way it tackles illness and learns to protect itself from future attacks. Vaccines are artificially developed and injected into the body to identify and fight specific germs. Natural immunity is the best defense mechanism for us. However, due to unpredictability of any unknown infection, the basic advantage a vaccine offers is safety and level of immunity.
Jennifer Gommerman, an immunologist at the University of Toronto says, “Vaccine is optimally tailored to generate an effective immune response.”
Over 200 vaccines are in process of being developed. Only a handful of them have undergone various trials and only a few have been cleared for use. Different types of COVID-19 vaccines that are being widely used include:
- Oxford-Astrazeneca, developed in India by the Serum Institute of India (SII) as Covishield
- Bharat Biotech’s Covaxin
