I just read yesterday that vaccinated doesn't protect anymore against the delta variant. The Pfizer Biontech vaccine had the highest immunity with 95%, but after tests in Israel where a large part of the population was vaccinated with Pfizer, the immunity dropped down to 65%. This is very scary, because we had so many variants already. With the next mutation the immunity could drop down to 30%.

  That's why the other country they declared travelled banned in international Airport. Cause they believe that's the only way to prevent and avoid the virus enter the Community. Hoping that they will obey the rules so that's it can ease this kind of variant. We all need to be safe and learn to obey the precautionary measurements.
