From Russia with vaccine

Opinion, , , , , , , , ,

The image above sums up the process of how a vaccine is developed. Now that we’re living in a global pandemic, a vaccine is seen as something that will bring an end to lockdowns, economic downturns, and a return to normalcy. Hence the next image:

Scientists and vaccine makers around the world are racing to make one that is safe and effective against SARS-CoV-2 with the World Health Organization leading the global effort at an unprecedented pace. At the moment, there are more than 165 vaccines being developed of which 31 are in various stages of human trials.

The latest to grab international headlines is dubbed Sputnik-V which was announced by no less than Russian President Vladimir Putin on August 11 as ‘ready for public use.’ Much like how the first Sputnik satellite drew global attention back in 1957, Russia’s COVID-19 vaccine brought much shock and awe the world over.

The shock as scientists and medical experts has condemned Russia’s approval of a COVID-19 vaccine that has skipped Stage 3 phase of clinical trials. Apart from the risks of side effects that could be harmful, a vaccine that turns out to be ineffective could undermine immunization efforts the world over and not just against the coronavirus. This would even play into the hands of anti-vaxxers to further their agenda. Overall, it threatens global health atop of the natural threat that is COVID-19 which has already killed millions, destroyed livelihoods, and caused worldwide suffering.

It didn’t help that President Durterte was quick to announce that Russia would be supplying the vaccine to the Philippines, something that he has been desperately clinging on to as his administration has struggled and miserably failed to contain the spread of COVID-19 in the country. Never mind that even Russian health experts have voiced their opposition to fast-tracking Sputnik-V, Duterte even volunteered to be the first Filipino to get injected.

Days after his late-night address, his spokesperson confirmed that indeed the Philippines would be participating in the Phase III trials for the Russian vaccine. Ironic since the administration has used another controversial vaccine – Dengvaxia, to score political points against the opposition.

If this is not madness, I don’t know what else is.

How long does SARS-CoV-2 survive in the environment?

Science, , ,

In a new report on the New England Journal of Medicine, investigators tested how long the SARS-CoV-2, the coronavirus that causes COVID-19, lasts in the air and on surfaces:

Viable in aerosols or mixed in air for 3 hours

Viable and detectable on the following surfaces:

Stainless steel and plastic – up to 72 hours

Cardboard – 24 hours

Copper – 4 hours

So frequent hand washing is still a very effective preventive measure as well as cleaning surfaces. Especially our mobile phones, tablets & keyboards.

You can read the full report here.

Stay safe and as much as possible, stay indoors.

How vulnerable am I to the COVID-19?

Daily dose, , , ,

The SARS-CoV-2 continues to spread throughout the world and there’s now talk of the COVID-19 reaching pandemic levels. It’s not going to be the end of the world or the start of a zombie breakout but one cannot avoid getting anxious. I myself have been worrying ever since reading about it back in December last year. Primarily because I have not been of the greatest of health; underweight, prone to allergic rhinitis which would easily develop into upper respiratory infection. That alone is enough to make life very hard for at least a couple of weeks until it gets resolved. To top it all off, I work in an office building where there’s a lot of foreign nationals on a daily basis.

So the worry is real. Thankfully most of the answers to the question in the title of this post, can be found on an article by Dr Edsel Maurice Salvaña, M.D., DTM&H, FPCP, FIDSA on Esquire Magazine:

Early data is showing that about 80% of people who get sick with COVID-19 will develop only mild symptoms, while 20% can develop more severe disease. The ones at highest risk for a bad outcome are the elderly and those with chronic illnesses such as diabetes, heart disease, and lung disease. A greater percentage of men compared with women with COVID-19 have died in China, and this may have been partly because more males smoke in China. Protecting your loved ones means avoiding unnecessary travel and practicing social distancing. Elderly people should avoid crowds and crowded places. Make sure everyone’s vaccinations for influenza and bacterial pneumonia are up to date since these can prove fatal if they occur at the same time as a COVID-19 infection. Now is also the best time to stop smoking.

Dr Edsel Maurice Salvaña, M.D. A Coronavirus Pandemic Isn’t the End of the World

I may not be young anymore but certainly not too old to be considered an ‘elderly’ just yet. Heart disease and diabetes free. However, I do have a history of lung disease and that’s where the worry really comes from. On the other hand some level of comfort comes from the fact that I don’t smoke cigarettes and having been on a drinking hiatus since last October, my exposure to second-hand smoke has been practically eliminated.

The real trick now is to keep my self in better health. Wash my hands more often and minimize travel. I even started to use my elbows in pushing the elevator buttons and consciously avoid touching door handles and the overhead bar at jeepneys.

In addition, I regularly keep myself updated with news & information about the COVID-19 from credible sources. Hopefully it would be enough to be spared from this disease along with my family. Hoping even more that a local outbreak would not happen even though the recent moves of the government in response to SARS-CoV-2 spread does not inspire confidence and even adds to our worries, there’s only so much that we can do.

Novel coronavirus 2019 disease & virus gets official names

Science, , , , ,

Two official names have been made public today in relation to the on-going pandemic, yes I said it, of novel coronavirus: the disease and the virus that causes it.

As per the World Health Organization:

For the virus:

Similar to how one should distinguish the AIDS (disease) from HIV (virus). With the official names now available, research and news reporting would be much clearer.

So let’s recap: the disease is called Coronavirus Disease-19 or COVID-19 and the virus is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
