Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2...021.
SAGE said moderately and severely immunocompromised persons should be offered an additional dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.

Overview
16 Dec 2021. This interim guidance pertains to heterologous primary and heterologous boosting schedules of Covid-19 vaccines. It focuses on heterologous schedules combining multiple vaccine platforms (e.g. a vectored vaccine followed by an... mRNA vaccine).

Herd immunity by mass vaccination offers the potential to substantially limit the continuing spread of COVID-19, but high levels of vaccine hesitancy threaten this goal. In a cross-country analysis of vaccine hesitant respondents across Latin America in January ...dbox">2021, we experimentally tested how five features of mass vaccination campaigns—the vaccine’s producer, efficacy, endorser, distributor, and current population uptake rate—shifted willingness to take a COVID-19 vaccine. We find that citizens preferred Western-produced vaccines, but were highly influenced by factual information about vaccine efficacy. Vaccine hesitant individuals were more responsive to vaccine messengers with medical expertise than political, religious, or media elite endorsements. Citizen trust in foreign governments, domestic leaders, and state institutions moderated the effects of the campaign features on vaccine acceptance. These findings can help inform the design of unfolding mass inoculation campaigns.

From the start of the COVID-19 pandemic until August 2021, extreme weather events have affected at least 139.2 million people and killed at least 17,242 people in at least 433 unique events. These figures are certainly an underestimate, as they do n...ot include estimates of numbers of people affected by extreme temperatures, or mortality during drought events.
One dimension of the compound risk of COVID-19 and climate extremes was the additional challenge of preparing for and responding to disasters during the pandemic, such as the constraints of physical distancing during evacuations and response operations.

The COVID-19 pandemic has affected job satisfaction among healthcare workers; yet this has not been empirically examined in sub-Saharan Africa (SSA). We addressed this gap by examining job satisfaction and associated factors among healthcare workers in Ghana and Kenya during the COVID-19 pandemic. W...e conducted a cross-sectional study with healthcare workers (N = 1012). The two phased data collection included: (1) survey data collected in Ghana from April 17 to May 31, 2020, and (2) survey data collected in Ghana and Kenya from November 9, 2020, to March 8, 2021. We utilized a quantitative measure of job satisfaction, as well as validated psychosocial measures of perceived preparedness, stress, and burnout; and conducted descriptive, bivariable, and multivariable analysis using ordered logistic regression. We found high levels of job dissatisfaction (38.1%), low perceived preparedness (62.2%), stress (70.5%), and burnout (69.4%) among providers. High perceived preparedness was positively associated with higher job satisfaction (adjusted proportional odds ratio (APOR) = 2.83, CI [1.66,4.84]); while high stress and burnout were associated with lower job satisfaction (APOR = 0.18, CI [0.09,0.37] and APOR = 0.38, CI [0.252,0.583] for high stress and burnout respectively). Other factors positively associated with job satisfaction included prior job satisfaction, perceived appreciation from management, and perceived communication from management. Fear of infection was negatively associated with job satisfaction. The COVID-19 pandemic has negatively impacted job satisfaction among healthcare workers. Inadequate preparedness, stress, and burnout are significant contributing factors. Given the already strained healthcare system and low morale among healthcare workers in SSA, efforts are needed to increase preparedness, better manage stress and burnout, and improve job satisfaction, especially during the pandemic.

This report challenges policy-makers and political leaders to tackle fossil fuel production and consumption as a health control issue, in the same way that smoking has been reduced and regulated. Fossil fuel combustion is a major source of toxic air... pollution that kills 7 million people every year, almost the same as the number of deaths caused by tobacco smoking.
In 2018, the World Health Organization (WHO) recognised air pollution as a major health risk factor. There is widespread public discussion about the effects of fossil fuel combustion and emissions on climate change… but what about the effect on our health? Climate change poses a threat not only to the health of the planet, but also to humans.
The case studies evaluated in this report offer examples of mechanisms that can be used to restrict the production and consumption of unhealthy commodities, so that the health, air pollution and climate communities can learn from one another, using shared approaches and language. These case studies show that the connection with health is a strong argument to support sustainable change.

The public health community has tried for decades to show, through evidence-based research, that safe water, sanitation, and hygiene (WASH) and clean cooking fuels that reduce ho...usehold air pollution are essential to safeguard health and save lives in low-income and middle-income countries. In the past 40 decades, there have been many innovations in the development of low-cost and efficacious technologies for WASH and household air pollution, but many of these technologies have been associated with disappointing health outcomes, often because low-income households have either not adopted, or inconsistently adopted, these technologies.
