  1. Purposefully infecting vaccine-study volunteers with coronavirus to speed up the development and approval process is unethical and fraught with the law of unintended consequences.
  2. Israeli real-world Pfizer vaccine study reports infection rates dropped by 33% in treatment group of 200K people >60 y.o vs 200K controls after 21 days, less than predicted by proponents of delaying 2nd dose. Stay on schedule until proven otherwise.
  3. In vitro studies reported in NEJM show that Pfizer/Moderna vaccines were still able to neutralize variant B.1.351 from South Africa despite reduction in neutralizing antibodies. Authors’ opinion is that vaccine remains efficacious. More to follow.
  4. Ontario study reports that one dose is good but two doses are better against variants. Keep on keeping on. #vaccineswork
