These two vaccines are great for the people in the 1A/1B/1C groups who are at greatest risk. The J&J recombinant vaccine should be very good for the majority of people. One and done! You can keep the Astra Zeneca/Oxford vaccine. I am not impressed how they messed up the dosing in their trial and how they tried to act like their error was no big deal, or even serendipitous. Also, no monkey virus for me. Irrational? Perhaps. But I won’t take it.
