ISLAMABAD, December 17 (online): Creating a vaccine in under 1 year is no small feat. While the corona virus pandemic made a new normal of mask-wearing and physical distancing, it also spurred global cooperation for vaccine research and distribution.
However, a vaccine is only effective if people are willing to receive it. With rapid research development, some may be concerned that the vaccine was rushed, and with these concerns comes vaccine hesitancy.
SARS-CoV-2 is a member of the coronavirus family. According to theNational Institute of Allergy and Infectious Diseases, there are hundreds of coronaviruses — including four that can cause the common cold, as well as the coronaviruses that sparked the SARS, or severe acute respiratory syndrome, epidemic in 2002 and the emergence of MERS, or Middle East respiratory syndrome, in 2012.
Scientists have been studying corona viruses for over 50 years. This meant scientists had existing data on the structure, genome, and life cycle of this type of virus.
