Why we need maximum suppression
Each time the virus replicates, there is an opportunity for a mutation to occur. And as we are already seeing around the world, some of the resulting variants risk eroding the effectiveness of vaccines.
That’s why we have called for a global strategy of “maximum suppression”.
Public health leaders should focus on efforts that maximally suppress viral infection rates, thus helping to prevent the emergence of mutations that can become new variants of concern.
Prompt vaccine rollouts alone will not be enough to achieve this; continued public health measures, such as face masks and physical distancing, will be vital too. Ventilation of indoor spaces is important, some of which is under people’s control, some of which will require adjustments to buildings.
Fair access to vaccines
Global equity in vaccine access is vital too. High-income countries should support multilateral mechanisms such as the COVAX facility, donate excess vaccines to low- and middle- income countries, and support increased vaccine production.
However, to prevent the emergence of viral variants of concern, it may be necessary to prioritise countries or regions with the highest disease prevalence and transmission levels, where the risk of such variants emerging is greatest.
The above authors also join the cloth mask denier community, calling for “double masks”:
adapting public health measures (such as double masking) and re-committing to health system arrangements (such as ensuring personal protective equipment for health staff)
Their plan has no end goal metrics and implies we need to do this forever. Some U.S. politicians are echo these comments, saying that until the entire world is vaccinated, the U.S., even if fully vaccinated, is not safe.
