COVID Vaccine, the Pfizer update

On Monday Pfizer announced to the world the vaccine, once it has been developing with Germany's BioNTech, was found to be more than 90?fective. If this is substantiated, it may be possible for countries to receive the vaccine before the end of the year.

The Vaccine is an mRNA Vaccine, a novel method that introduces viral RNA into the body via a viral coat. The vaccine is incorporated into the person's cell, where the viral RNA is read and viral proteins are produced, including the coronavirus coat proteins. As the body reads and recognizes these proteins, it produces antibodies against these viral proteins and activates immune T cells against the virus.

The Pfizer results are based of a phase 3 clinical trial with 43, 538 participants with a diverse background. In this trial, the participants were split between those receiving a vaccine, and those who received a placebo with no effect. The vaccine is administered in two parts, with a 90?ficacy obtained 7 days after the second dose. This would mean a person is vaccinated just 28 days after the initial vaccination.

The FDA usually looks for a minimum 50?ficacy in vaccination when approving new vaccines. It may surprise you that the annual flu jab is also estimated to be 50?fective. The data from Pfizer was verified by an external, independent Data Monitoring Committee. It used data from 94 patients enrolled in the trial and subsequently developed COVID. It is from this groupset that 90% of efficacy is obtained. This is not the final data analysis, and further publications are expected in late November, with a potential FDA Emergency Use Authorisation approval if the data continues to show promise.

If approved, Pfizer has the ability to make 50 million shots before the end of the year, and 1.3 billion by the end of 2021. Many countries are clamoring for their fair share of these limited resources; the US has already negotiated 200m shots, UK 50m, and Germany (one of the major financers for the Pfizer vaccine) over 300m for European Countries.

We should emphasize that rapid vaccine development on this scale at this speed was unheard of prior to COVID. Usually, the animal studies for vaccines can take 1-2 years. In that time Pfizer and others have managed phase 1-3 clinical trials in humans, something that usually takes upwards of 10 years.

There are many unanswered questions that remain from this information.

  1. How safe is the vaccine? Whilst safety information was not published, overall the vaccine appears to have minimal side effects. This is particularly difficult to state however since mRNA vaccines have never been used in people before.
  2. Does the vaccine prevent transmission? In theory, yes. If you are immunized the replication of the virus should be limited significantly, so the number of viruses in each cough will be much lower. However, we do not have data to prove that there is no transmission, but that is also because we have very little data overall.
  3. How long does the protection last? This is a very critical question. The 90?fectiveness rate was calculated just 7 days after the second shot, but it is likely this will change as data is collected over the long term. Some studies have suggested the antibody response fades within months following COVID infection. T Cell immunity on the other hand can stay for years, and it may be the effectiveness of creating a T cell immunity that dictates just how good this vaccine will be .

Flexible Work Schedules with Telehealth Support: A Smarter Approach to Employee Wellbeing

The modern workplace is undergoing a significant transformation. Rigid office hours and traditional healthcare access models are giving way to flexible work schedules and digital health solutions. One of the most impactful combinations emerging in corporate wellness is flexible work schedules with telehealth support.

This integrated approach addresses two critical challenges faced by today’s workforce: work-life imbalance and delayed healthcare access.

 

Why Workplace Health Models Need to Change

According to NITI Aayog and EY-FICCI workforce reports, Indian employees face rising levels of:

  • work-related stress
     

  • lifestyle diseases
     

  • burnout
     

  • absenteeism
     

Long working hours, commuting stress and limited time for medical visits worsen health outcomes. Flexible work arrangements and telehealth support directly address these gaps.

 

What Are Flexible Work Schedules?

Flexible work schedules allow employees to:

  • adjust start and end times
     

  • work remotely or in hybrid formats
     

  • manage personal commitments alongside work
     

Flexibility empowers employees to align work with their physical and mental health needs.

 

Understanding Telehealth Support

Telehealth uses digital platforms to deliver healthcare services such as:

  • online doctor consultations
     

  • follow-up care
     

  • preventive health advice
     

  • mental health support
     

It eliminates geographical and time barriers to healthcare.

 

Why Combining Flexibility with Telehealth Works

Individually, flexibility and telehealth are beneficial. Together, they create a powerful wellness ecosystem.

This combination allows employees to:

  • consult doctors without taking leave
     

  • manage chronic conditions proactively
     

  • address early symptoms promptly
     

  • reduce healthcare delays
     

 

Health Benefits for Employees

Reduced Stress and Burnout

Flexible schedules reduce time pressure, while telehealth removes healthcare-related anxiety.

 

Improved Access to Preventive Care

Employees are more likely to seek early consultations when care is convenient.

 

Better Management of Chronic Conditions

Conditions like hypertension, diabetes and thyroid disorders require regular follow-up, which telehealth supports efficiently.

 

Enhanced Mental Wellbeing

Tele-mental health services enable confidential and timely support.

 

Improved Work-Life Balance

Employees can prioritise health without compromising job responsibilities.

 

Productivity Benefits for Employers

Reduced Absenteeism

Quick access to care reduces prolonged sick leave.

 

Improved Employee Engagement

Health-supported employees show higher motivation and loyalty.

 

Lower Healthcare Costs

Preventive care reduces long-term medical claims.

 

Strong Employer Branding

Wellness-focused policies attract and retain talent.

 

Evidence Supporting Flexible Work and Telehealth

According to WHO and Lancet workplace health studies:

  • flexible work reduces stress-related disorders
     

  • telehealth improves healthcare utilisation
     

  • preventive care lowers chronic disease burden
     

Indian corporate data mirrors these findings, especially in hybrid work environments.

 

Role in Preventive Healthcare

Preventive healthcare focuses on early risk identification and lifestyle management.

Flexible schedules with telehealth support:

  • encourage routine checkups
     

  • support ongoing health monitoring
     

  • enable early intervention
     

This aligns with India’s preventive healthcare priorities outlined by NITI Aayog.

 

Addressing Common Concerns

Productivity Loss Myth

Multiple studies show flexible work improves output rather than reducing it.

 

Quality of Telehealth

Telehealth is effective for most primary care and follow-up needs.

 

Data Security

Modern telehealth platforms follow strict privacy and data protection standards.

 

Ideal Use Cases in the Workplace

This model is particularly effective for:

  • IT and corporate offices
     

  • remote and hybrid teams
     

  • organisations with distributed workforce
     

  • high-stress work environments
     

 

Implementation Best Practices

To maximise impact:

  • set clear flexibility guidelines
     

  • integrate telehealth access into HR benefits
     

  • promote preventive consultations
     

  • track wellness metrics
     

Leadership support is key to adoption.

 

Long-Term Organisational Impact

Organisations adopting this model report:

  • improved employee health indicators
     

  • reduced burnout
     

  • stronger workplace culture
     

  • sustainable productivity gains
     

Wellbeing becomes a strategic advantage.

 

Conclusion

Flexible work schedules with telehealth support represent the future of employee wellbeing. By removing barriers to healthcare access and allowing employees control over their work routines, this approach promotes preventive care, reduces stress and enhances productivity. As workplaces evolve, integrating flexibility with digital health support is not just an employee benefit—it is a strategic investment in long-term organisational health and resilience.
