What Happens If Covid-19 Vaccine Cannot Be Found?


Many companies around the world are working on the Covid-19 vaccine, but so far there is no guarantee of finding it. So what will happen if there is no vaccine for this disease?

Tammy Hoffmann, professor of clinical epidemiology and medical professor Paul Graffitiziou, at Bond University in Australia wrote an article on this issue in Channel News Asia on April 24.

The curve of the Covid-19 epidemic has been flattened in many countries around the world when quarantine measures were taken to prevent the number of infections peaking too quickly, causing the collapse of the health system. But there is currently no cure or vaccine for this disease.

We are being saved by non-drug interventions such as quarantine, social spacing, hand washing, wearing masks and other protective devices.
We all hope to have the Covid-19 vaccine by 2021. But what should we do now? And more importantly, what if there is no vaccine?

The world is betting too much on the Covid-19 vaccine?
The world has focused most of its research funding on finding an effective vaccine and drug for Covid-19. That effort is important, but it must be accompanied by research on improving non-drug interventions - things that have proven effective so far.
However, the debate about such measures is still taking place in the world such as: Should the public wear a mask? Should we stand 1, 2 or 4 meters apart? We should wash our hands with soap or disinfectant. The world needs clear answers to those questions right now.

Non-pharmacological interventions receive much less attention than drug development and testing.
During the Covid-19 pandemic, millions of dollars were given to research groups around the world to develop the Covid-19 vaccine and to test drug treatments.
Hundreds of clinical trials of drugs and vaccines are underway, but only a few trials of non-pharmacological interventions have been found, and none have been tested on how to improve compliance. them.

We all hope for a global effort to develop Covid-19 vaccines or medicines successfully. But many experts, including Ian Frazer, who developed Australia's HPV vaccine, think this will not be easy or quick to bear fruit.
If the expectation of an effective vaccine or drug treatment fails to materialize, we will need a "Plan B" in which only non-pharmacological interventions are used.

That's why we need high-quality research to find out which methods work and how to make them as effective as possible.
You may think that washing your hands, wearing a mask and social spacing are simple and do not need research. However, the reality shows that non-drug interventions are often very complicated.
Research is needed to understand not only the operational components of the intervention system (e.g. handwashing), but also how to help people get started and continue to implement those measures and how convey these messages to people.

Non-pharmacological interventions also need clear research
Developing and implementing an effective non-pharmacological intervention is very different from developing a vaccine or drug, but it is also very complex.

For example, the # Masks4ALL (All wearing a mask) campaign encourages people to wear masks. But the issues that are not or are rarely mentioned are: the type of mask, the material of the mask, the time and place to wear the mask.

Hand washing sounds simple. But how many times do I wash my hands every day? Twice a day, 10 times a day? What is the best way to teach people to wash their hands properly?
If people don't know how to wash their hands properly, is hand sanitizer better than soap and water?
These are just some of the things we don't know about non-drug interventions.

Recently, Prof Tammy Hoffmann and Paul Graffitiziou reviewed all controlled randomized trials for physical interventions to prevent the spread of the Covid-19 disease virus, including interventions. cards such as masks, hand hygiene, eye protection, social isolation, and any combination thereof.
They found a series of confusing trials, many low quality trials or small sample volumes, and some types of interventions that had not been randomized.

In addition, in addition to a number of measures that have been applied, it is necessary to study other non-pharmacological measures related to the environment such as heating, ventilation, air-circulation, and the viability of the virus. surfaces.

We need to know those measures as soon as possible so that we don't waste time, effort and resources on ineffective things.
We need to achieve rapid behavioral change on a large scale. Contradictory messages will create confusion and make behavior change much more difficult.

The Covid-19 vaccine cannot save people from every pandemic
Moreover, if the Covid-19 vaccine appears, we will be able to get out of this pandemic quickly, but what happens when another pandemic or pandemic arrives?

Vaccines prevent only one disease. So when a new virus threatens, we will encounter the same situation.
However, non-pharmacological interventions can be used to protect us against many other viruses.

In short, according to professors Tammy Hoffmann and Paul Graffitiziou, focusing all of the funds, efforts, and resources on vaccine and drug research can become a devastating and costly mistake both medically. and economy.
