WHY NEW COVID-19 VARIANTS NECESSITATE MORE VACCINE RESEARCHES
The new emerging variants has necessitate researchers to embark on more studies to tackle new waves of the pandemic
Many countries are counting on vaccines to build sufficient immunity in their populations so that SARS-CoV-2, the virus that causes Covid-19, isn’t able to find enough people to infect, causing transmission to eventually stop.
But even in countries with a high proportion of people inoculated with highly effective vaccines, it’s unclear whether it’s possible to reach the so-called herd immunity threshold anytime soon.
Researchers warn that the virus is apt to be circulating among us for a long time, although it’s likely to become a less potent foe. This is another development that propagate a refine and redefinition of existing vaccines to accommodate and tackle reoccurring viruses.
