Pfizer will get full approval on Monday. The waffling by governments, unions and businesses should end. Also, Pfizer will be allowed to advertise and otherwise promote their vaccine.
===============
Many companies and schools were afraid of law suits and other actions related to a vaccine that wasn't fully approved. We will see lots more concerts like the concert tonight: no vaccine, no admittance.
As an aside, I think it negligent for teacher's organizations and unions to allow their members to work without being vaccinated; ditto for health care workers and first responders.
Hopefully, much of this will change soon. In any case, it is too late to prevent all the school closings, and the hundreds of thousands of cases (and then hospitalizations and deaths). Schools (especially high schools) will be breeding grounds for the virus. IMO, thousands of schools will be closed within a month.
Masks are NOT really the primary issue in schools. The masks we use help, but they are no match for the variant. The bottom line is that NO ONE OVER 12 YEARS OLD should allowed on school grounds without proof of vaccination. Vaccines for those under 12 needs to be approved ASAP. If schools are forced to accept unvaccinated and unmasked children, then they should be segregated and taught by volunteer staff, and allowed ZERO contact with the other children.
