So, one of the biggest studies to date on ivermectin for COVID-19 has issues significant enough that, if not fraud, are so serious that it invalidates the study without further explanation

As high-income countries have secured much of the #Covid19vaccine supply, many low-income countries have barely begun the immunization process. We need political courage to end vaccine injustice now and political vision to negotiate rules for averting future inequities.

Health care workers who had received a dose of ChAdOx1 nCoV-19 were offered either ChAdOx1 nCoV-19 or mRNA-1273 9 to 12 weeks later. Levels of S-specific and RBD-specific IgG increased by a factor of 5 after ChAdOx1 nCoV-19 and by a factor of 115 to 125 after mRNA-1273.

Mix and match vaccines?
2 doses AZ vs AZ and then Pfizer:

"HIV, TB, and malaria shouldn’t be labeled as “just” epidemics or endemic. They are pandemics that have been beaten in rich countries. Allowing them to persist elsewhere is a policy choice and a budgetary decision"https://t.co/MVCS960cN5
