With the gatslag of the announcement that the AstraZeneca vaccine does not work against the SA variant, the health department seems to favour the J&J vaccine since its SA trial leg encountered the SA variant which none of the others did. However, when you unpack the numbers, it is not hopeful as the effective sample size is exceedingly small. I posit, with good reason, that the effective sample size on which they base their unimpressive efficacy of 57% is 49!

The Brazilian Variant
South Africa always seems to hit the worldwide headlines for all the wrong reasons. Normally, the reasons are self-inflicted but South Africa has again become a household name when a South African Variant of the SARS-CoV-2 was discovered and found to be more infectious, if not more lethal. Luckily, we’ve been upstaged by a new variant, known as the Brazilian Variant, that popped up in Manaus and overwhelmed their medical system within 24 hours.
Life-long effects of viral diseases
It is sobering to consider the possible long-term impacts of this virus on the body and this possibly dispels the efficacy of advocating herd immunity.
The first prize must be not to get it at all!
Saving a person suffering from Covid-19
This is not a scare tactic or crying wolf to get everybody to adhere to the recommendations regarding Covid-19 but hopefully it will have the required salutary effect. Having had a wife who was intubated for six and half weeks, I can comprehend what these patients are experiencing. For them it is far worse as unlike Janine, these patients are not in a coma.

Normally when there is a catastrophic humanitarian crisis, communities and countries unify and coalesce. By doing so, they all not only contribute to sharing the burden, but they also provide solace to those in mourning. Instead, bereft of leadership in both the national and international arenas, responses have become mired in selfish agendas. This is no more starkly evident than in the United States.
Why is this so?

I am increasingly of the opinion that the wearing of masks is an imperative. I have just finished listening to a Czech doctor who said that it is mandatory to wear masks the moment they step outside and their infection rate is testimony to those measures. I’m not talking about the N95 mask but the ordinary pleated mask. Its all about risk reduction.

If one doubts the terrible economic consequences of the disease, then these Nasa photos will jolt you out of your complacency. They show the amount of Nitrogen Oxide in the atmosphere which is primary due to the usage of motor cars but also any industrial process that burns fuels at high temperatures.
The first photo overs a period in January before lockdown – voluntary as well as involuntary – and the second covers the period after it has taken effect.
