THE CHALLENGES FACED IN MAKING A VACCINE FOR COVID-19 — Part 2

Previously we’ve seen the difficulties researches face in trying to make a vaccine. But even if we make a vaccine, that’s just half the battle. Viruses are unique because they can mutate, and they can mutate to astonishing degrees. In humans mutations to tiny parts of our DNA can cause severe diseases or even death. In viruses mutations can change their structure, making them more infective and giving them a new coat. It gives them a survival advantage, the ability to evade our immune system and make our vaccines ineffective. This is why we need a new flu vaccine every year.

If it takes months to a year to develop a vaccine, it will be based off the virus found in December 2019. By this time the virus may have spread and mutated to such a degree that it is not effective. This does not mean all the effort was for nothing. Going through the steps and understanding the issues faced with making a COVID-19 vaccine can make the process quicker for subsequent vaccines against its mutated versions.

FAILURES FROM THE PAST

These issues were faced during the Ebola and Zika virus epidemics, and many large companies are understandably hesitant to develop vaccines for COVID-19. Ebola first broke out in 2014, and it was only in December 2019 that the first vaccine was approved for use by the European Commission and the United States. This is despite multiple large institutes in Canada and the UK working together to develop it.

13 different Ebola vaccine candidates had been identified soon after the outbreak, but none had been tested on humans. Unfortunately this is the most expensive part of development, and the area biopharmecuticals stand to loose the most money. Return on investments is also low, since epidemics usually take place in poorer countries, and the potential customers are unable to pay the high prices for these brand new treatments. It is an unfortunate realisation that research into medicines is driven by rich countries, for diseases that affect the rich.

WHERE ARE WE NOW?

This is all well and good, but what does it mean for COVID-19? We know we cannot rush a vaccine, because a poorly designed vaccine with unknown side effects can cause more harm than good, especially if given to children or the elderly. Currently the WHO are tracking 31 different attempts at making a COVID-19 vaccine, using different methods as discussed before. All of these are currently in the pre-clinical stage, focusing on isolating parts of the virus and creating a target the body will recognise and react to.

Researchers at the University of Queensland were one of the first to start using the genetic code of COVID-19, released openly by Chinese researchers. They have developed a test vaccine within 6 weeks using state-of-the-art genetic techniques, used for the first time. If animal models prove successful then human testing might begin within 6 months. In the pharmaceutical industry advancements this quick are almost unheard of.

Additionally over 293 clinical trials are taking place in China using existing drugs on the market. The advantage is we already know these drugs are safe to use in humans, but we are trying to work out if they will work against COVID-19. Some scientists are also looking at medications that were initially developed against SARS and MERS, but never completed because these outbreaks died down and the medication was no longer required.

Its not all doom and gloom. Challenges drive innovation, and we are already benefitting from this. New forms of genetic sequencing, new methods for extracting viral proteins, new techniques in creating a vaccine. These innovations are already benefitting us on the drive to create an effective vaccine for COVID-19, and they will benefit us in the future when the next pandemic hits.

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.
