Thank goodness for a light at the end of the tunnel. It seems to me that these vaccines are going to WORK! We still need to find out exactly how long-lasting they are, how many boosters might be necessary, etc., and we also have to overcome the fact that somewhere over 30% of people say they won't get the vaccine when it becomes available to them. We need more than 70% of the population to get it in order for us to have herd immunity, so the second crisis we're fighting is misinformation and conspiracy theories.
Hooray for Pfizer and Moderna!
