Will You Need COVID-19 Booster Shot? Doctors, Vaccine Makers Explain

Over a third of the U.S. population have been fully vaccinated.

The COVID-19 pandemic is far from over. While in the U.S. a third of the population are now fully vaccinated, many countries are struggling with rampant infection rates and record death tolls as new mutations emerge worldwide. And even in developed nations where new COVID-19 cases keep falling thanks to vaccine rollouts, there is now no way of knowing exactly how long immunity will last.

Both realities call for a serious discussion about a booster shot or an entirely new vaccine that can adapt to the constantly changing virus.
