Keeping It Cool


Almost daily, we're informed about  new age groups that are to be vaccinated next. We're assured there's plenty of vaccine for the whole population. including children. Just make the appointment, and come .

I feel some urgency in the air about it, and that makes me think of the existence of possible vaccine storage/handling issues. I suspect the bottles have to be used quickly to avoid decreased potency and loss of patient's confidence.

After all, it's a tremendous logistical challenge. The vaccine units make a long journey from the centers of distribution -  to clinics - to patients. The journey involves planes, trains, trucks and special delivery containers adequately refrigerated (by dry ice). 

Pfizer's vaccine has to be kept at -70 degree Celsius. Moderna's vaccine is said to be stable at regular freezer temperatures. Both require two doses for full effect, which might complicate things.

Hopefully, a significant drop in the bad numbers of covid-19 victims is to be expected by the end of the month, due to the vaccines and the lockdown. In the meantime, people are strongly advised by the medical experts to keep to masks and distancing, as the british mutation is hitting hard; it especially likes the young ones, and pregnant women in their advanced stage of pregnancy.

Here's a 'talk back' seen online: ' Of course, the british version of the virus is more efficient than the chinese one; wait till  the german or swiss version comes along - what precision, what perfection'...

Inferno


Beirut is in the news with the terrible disaster that has occured in the city's port. It seems the explosion was caused by poor storage of over two thousand tons of ammonium nitrate. Things are still under investigation .

It isn't the first time , and it probably won't be the last time that man-made disaster happens. 'To err is human'; humans make mistakes (i.e. the errors at the nuclear reactor in Chernobil). Negligence is also human ( the faulty storage of the ammonia gas in Beirut port). The consequences of these human actions are devastating!

Unlike natural disasters (earthquakes, floodings, volcano eruptions, hurricanes etc..) man-made disasters could be prevented, but not always, as they usually revolve around chemicals. This stuff requires extreme care and caution .
Sometimes disasters are a combination of both the natural with the
man-made, like forest fires, for example.

We humans feel helpless. We have no control on  Nature's sent disasters, and little, if any, on the man-made ones.

We can be careful, of course, as to where we choose to live or work: not too close to an industrial zone (chemical and biological hazzards, explosions), not near  a big body of water (flooding) or a forest (fire danger).   But not much beyond that.

In any case, I put my trust in God and pray to Him :to guide , protect , help us when in danger.
