This article highlights the need to stop massive spreads as variants will be created and will hamper vaccine efficacy. Perhaps its what the pharma want a perpetual need for vaccination. – Global rollout of vaccines is no longer a guarantee of victory over Covid-19 | Coronavirus | The Guardian
“No one is truly safe from Covid-19 until everyone is safe. We are in a race against time to get global transmission rates low enough to prevent the emergence and spread of new variants. The danger is that variants will arise that can overcome the immunity conferred by vaccinations or prior infection.”
“There are currently at least three documented Sars-CoV-2 variants of concern:
B.1.351, first reported in South Africa in December 2020
B.1.1.7, first reported in the United Kingdom in December 2020
P.1, first identified in Japan among travellers from Brazil in January 2021
Similar mutations are arising in different countries simultaneously, meaning not even border controls and high vaccination rates can necessarily protect countries from home-grown variants, including variants of concern, where there is substantial community transmission.
If there are high transmission levels, and hence extensive replication of Sars-CoV-2, anywhere in the world, more variants of concern will inevitably arise and the more infectious variants will dominate. With international mobility, these variants will spread.”
“Recent real-world evidence from the UK suggests both the Pfizer and AstraZeneca vaccines provide significant protection against severe disease and hospitalisations from the B.1.1.7 variant.”
“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.”
“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.”
Brazil and India still a big concern for the global variant production
Variants seem to be inevitable in test tubes such as Brazil and India
Confirmation per capita in every state seems to all be approaching 10%. MI leads confirmation. CA leads death
Wayne MI leads confirmation. LA leads death
Global vaccine front. Interesting to see Chile being so high per capita.
