The fact is no vaccine is 100% effective. Would you recommend that your grandchildren not be vaccinated against polio because it wasn't 100% effective? All the data presented has shown Pfizer and Moderna to be 95% effective. If everyone got either of these vaccinations, we would stop the pandemic. That isn't to say that we haven't experienced problems in rolling out the vaccination process. As a scientist for my entire life, I have a great respect for both the FDA and the CDC. if you read historical books on what life was like 100 years ago, you would appreciate their roles. (For example -- The Poison Squad by Deborah Blum - there was also a PBS show on this.)
