VACCINE

 These last few weeks I have heard that the COVID vaccine is close. This is race of who is going to come to market soon their vaccine first. But is it safe? I have heard that Pfizer´s vaccine is 90% effective while Moderna´s is 95% effective, but according to some experts who have made the news, these vaccines would be effective for mild to moderate cases.

So I think there is still a long time to  find a vaccine that is effective for severe cases and prevents mortality from the disease.
