CNN: Just like experts predicted, coronavirus cases are ticking back up around the world.
India has recorded its highest number of Covid-19 cases in a single day since the pandemic began, with more than 100,000 confirmed infections yesterday.
South Korea’s health leaders are warning of another surge after the country recorded more than 500 new cases for the fifth straight day. In Europe, a third wave of hospitalizations and deaths has already arrived.
Covid-19 variants are mostly to blame for the new rises, but as US officials have warned, lax safety measures are giving these variants even more strength.
Now, we have more to worry about, like how long coronavirus vaccines may actually protect people.
Doctors are worried that coronavirus may end up being like influenza, which requires a new vaccine every year because the strains mutate so quickly.
