Developing A Vaccine For COVID-19? Part 1

It is often stated vaccination has made the greatest contribution to global health of any human discovery, other than clean water and sanitation, and their impact on everyday life is immediately evident. We have managed to completely eradicate two major infections from existence (smallpox and rinderpest) , and the WHO are working towards adding polio to that list.

In these cases the numbers speak for themselves. It is estimated that the eradication of smallpox in 1980 has saved 5 million lives per year, adding up to 150 to 200 million by 2018. Common vaccination programmes for polio, measles, mumps, rubella, rabies and hepatitis A have prevented nearly 200 million cases from occurring in the US alone over the past 50 years, and 4.5 billion instances of the diseases worldwide.

We have achieved a 99% immunisation rate against polio, preventing children from suffering crippling paralysis, and only 3 countries remain. Sadly, around 1.4 million children under 5 still die from preventable diseases each year as they do not have access to these life saving vaccines, but charities and public health organisations around the world are working hard to improve access.

So what are vaccines? And how will they help is in the face of the latest pandemic? Here we will go into the challenges behind making vaccines, and why a vaccine against COVID-19 is unlikely to be ready in the next few months, or even this year.

WHAT IS A VACCINE

The human body’s immune system is incredibly smart. It is able to distinguish between infective organisms, such as bacteria, viruses and parasites, from our own body’s cells, target these invaders for destruction and keep our bodies healthy. Even better, the body remembers any previous infections it has had before, recognise these previous infections even quicker and even eradicate the disease before we know we are infected.

Vaccines target the immune system’s memory by presenting them with pieces of these infective diseases. The small amounts do not cause any infective symptoms, but if the person is infected later in life their body will mount a quicker response and prevent them from falling ill. These vaccines can contain broken up parts of the organisms, “dead” organisms or “live” versions that have been severely weakened so they cannot cause any harm.

In summary, medicines treat us when we get an infection. Vaccines make sure we never suffer from an infection in the first place.

THE HURDLES WE FACE IN RESEARCH

Making a vaccine is a difficult process, one that can take 3–5 years and cost hundreds of millions of dollars, sometimes billions of dollars. This is because there are many difficult steps to be taken in the process of creating a vaccine that is effective, but more importantly one that is safe.

To start with the troubling organism has to be identified. For COVID-19 it took a few weeks to recognise the virus responsible, and some time more to understand its genetic code and grow the virus in lab conditions. We then have to understand the virus, how it infects, how it causes symptoms, and how it has mutated compared to the coronaviruses responsible for SARS and MERS.

After this, we have to isolate parts of the virus our immune system will recognise. This is usually the outside coat of the virus. The DNA responsible for making these parts need to be found in the virus’ genetic code, and put inside other “skeleton” viruses. This will force the dummy virus to look like coronavirus, without the ability to infect and kill someone.

These dummy viruses can be injected into animals to see if it causes an immune reaction, whether the immune system recognises it as the coronavirus responsible for COVID-19, and whether it will protect the animal from the real COVID-19. Up to now the research has likely cost a few million dollars. The next step is when the price inflates up to billions.

If the vaccine appears safe in animals, it can be tested in humans. This can be dangerous at first, since we don’t know whether a vaccine that works in an animal will work in a human. And we don’t know if there will be any side effects to the vaccine. Human testing has to be very thorough, very careful, and safe for use. If you give too much of the virus it might make the person sick, too little and it wont immunise the person. These clinical trials can take years, and if the vaccine fails at this point its back to the drawing board, to try another step.

Now we have a basic understanding of what vaccines are and why it takes so long to make a vaccine. In the next part we will look at why viral vaccines can cause even more problems, and how far we have come with the COVID-19 vaccine,

Only Health-Based Rewards: Why Wellness-Focused Incentives Drive Healthier Workplaces

Corporate rewards have traditionally focused on monetary incentives, gift cards or generic perks. However, organisations are increasingly realising that such rewards offer only short-lived motivation. Only health-based rewards, such as massages, gym bags and fitness trackers, represent a more effective approach to corporate wellness by reinforcing healthy behaviours that deliver long-term benefits.

In India, where lifestyle diseases are rising rapidly among working professionals, aligning rewards with health outcomes is no longer optional.

What Are Health-Based Rewards?

Health-based rewards are incentives designed specifically to improve or support employee wellbeing.

They focus on:

physical health
mental wellbeing
preventive care
recovery and stress relief

Unlike cash incentives, they encourage repeated healthy actions.

Why Traditional Rewards Fall Short

Cash rewards and generic gifts:

provide temporary satisfaction
do not influence daily habits
fail to support long-term wellbeing

Behavioural studies show that incentives disconnected from health goals have limited preventive impact.

The Case for Only Health-Based Rewards

Health-based rewards directly reinforce behaviours such as:

regular physical activity
stress management
recovery and self-care
preventive health participation

WHO workplace health guidelines emphasise incentives that promote sustained behaviour change.

Types of Effective Health-Based Rewards

Massages and Recovery Therapies

Massage therapy:

reduces muscle tension
lowers stress hormones
improves circulation

Monthly or quarterly massage rewards support physical and mental recovery.

Gym Bags and Fitness Gear

Practical fitness accessories:

encourage regular workouts
reduce barriers to exercise
promote active lifestyles

Visible gear reinforces identity as a health-conscious individual.

Fitness Trackers

Fitness trackers:

track steps, activity and sleep
create accountability
encourage daily movement

Data-driven feedback increases participation and motivation.

Psychological Impact of Health-Based Rewards

Health rewards create:

intrinsic motivation
positive habit reinforcement
long-term lifestyle shifts

Unlike cash, they associate rewards with self-care rather than consumption.

Impact on Employee Health Outcomes

Regular participation in wellness incentives leads to:

improved physical activity levels
reduced stress
better sleep patterns

ICMR data links activity-based interventions with lower lifestyle disease risk.

Benefits for Employers

Reduced Healthcare Costs

Preventive health rewards reduce chronic disease burden over time.

Improved Productivity

Healthy employees demonstrate:

better focus
fewer sick days
higher energy levels

Stronger Wellness Culture

Health-first rewards signal genuine organisational commitment.

EY-FICCI reports show preventive wellness programs deliver measurable ROI within 12–18 months.

Why Health-Based Rewards Work Better in India

Indian workplaces face:

long working hours
sedentary routines
high stress levels

Health rewards directly address these risks rather than ignoring them.

Aligning Rewards With Preventive Healthcare

Health-based rewards complement:

health screenings
fitness challenges
mental wellbeing programs

This integrated approach strengthens outcomes.

Avoiding Pitfalls in Reward Design

Effective programs:

avoid one-size-fits-all rewards
offer choice within health categories
ensure inclusivity

Poorly designed incentives reduce engagement.

Measuring Success of Health-Based Rewards

Success indicators include:

participation rates
health screening uptake
employee feedback
reduced absenteeism

Data-driven evaluation improves program effectiveness.

Long-Term Behaviour Change

Sustained wellness improvement requires:

consistency
reinforcement
meaningful incentives

Health-based rewards support gradual but lasting change.

Role of Leadership Support

Leadership participation:

increases credibility
boosts engagement
normalises wellness culture

When leaders embrace health rewards, employees follow.

Health-Based Rewards and Mental Wellbeing

Rewards such as massages and fitness trackers:

reduce burnout
improve mood
enhance resilience

Creating a Preventive Wellness Ecosystem

Only health-based rewards work best when combined with:

education
screenings
access to care

WHO emphasises integrated wellness ecosystems for maximum impact.

Conclusion

Only health-based rewards represent a strategic shift from short-term perks to long-term wellbeing investments. Incentives such as massages, gym bags and fitness trackers actively promote healthy habits, reduce lifestyle disease risk and strengthen workplace wellness culture. By aligning rewards with preventive health goals, organisations create meaningful engagement, healthier employees and sustainable productivity gains. Health-focused incentives are not just rewards—they are tools for lasting wellbeing.
