| At the beginning of 2020, Indonesia was surprised by the emergence of a new type
of virus outbreak (SARS-CoV-2) whose disease is called Coronavirus Disease
2019 (COVID-19) and has caused a pandemic that has not yet ended. Over time,
the Indonesian government issued a new policy to be able to make peace and
coexist with the Corona Virus, and it was called the new normal era. As an attempt
to reduce these cases, there are a number of studies from several countries
regarding the creation of a vaccine. |
