Respiratory Vaccines Are Not Always 100% Effective: ICMR

Addressing a question about the Drug Controller General of India's guidelines about COVID-19 vaccine development, Dr. Balrama Bhargava, Director General of the ICMR said that vaccines are not always 100% effective. 

Dr. Bhargava even cited the WHO's response wherein it states that vaccines against COVID-19 with a 50-100% effectiveness will be helpful to fight the virus. 

Safety, effectiveness, and immunogenicity of the vaccine are the most important aspects of vaccine production.
