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,

Monthly Field Day with Patients & Staff: Building Trust, Engagement, and Wellbeing

Healthcare is built on relationships. While diagnosis, treatment and technology are critical, the human connection between patients and healthcare staff remains central to healing and recovery. A Monthly Field Day with Patients & Staff is a thoughtful initiative designed to strengthen these relationships by creating opportunities for interaction outside routine clinical environments.

In today’s healthcare systems, patient engagement and staff wellbeing are recognised as essential components of quality care. Monthly field days provide a structured yet informal platform to support both.

What Is a Monthly Field Day with Patients & Staff?

A Monthly Field Day is a planned engagement event where patients and healthcare staff come together to participate in non-clinical activities. These events focus on:

interaction
wellbeing
communication
community-building

They are not medical appointments but shared experiences that promote trust and understanding.

Why Field Days Matter in Healthcare

Healthcare Is Emotionally Demanding

Patients often experience anxiety, fear and uncertainty. Staff face long hours, emotional stress and high responsibility. Field days offer a space for:

relaxed interaction
emotional connection
mutual understanding

This humanises care delivery.

Strengthening Patient–Staff Trust

Trust grows through:

open communication
shared experiences
consistent engagement

Field days reduce perceived barriers between patients and healthcare teams.

Benefits for Patients

Improved Comfort and Confidence

Patients feel more at ease when they know the people involved in their care beyond clinical roles.

Better Engagement in Care

Engaged patients are more likely to:

ask questions
follow care plans
attend follow-ups

This leads to improved health outcomes.

Emotional and Social Wellbeing

Social interaction, light activity and positive experiences support mental and emotional health, especially for patients with chronic conditions.

Benefits for Healthcare Staff

Reduced Burnout

Regular non-clinical engagement helps:

reduce emotional fatigue
restore motivation
improve job satisfaction

Stronger Team Relationships

Shared activities strengthen teamwork and communication among staff members.

Renewed Sense of Purpose

Seeing patients outside stressful clinical settings reinforces the meaningful impact of healthcare work.

Organisational Benefits

Enhanced Patient-Centered Culture

Field days reinforce values of empathy, accessibility and respect.

Improved Patient Satisfaction

Trust and familiarity contribute to better patient experiences and feedback.

Better Communication and Feedback

Informal settings encourage honest dialogue, helping organisations understand patient needs and expectations.

Activities Commonly Included in Field Days

Wellness Activities

gentle exercises
stretching or yoga
breathing sessions

Educational Interactions

health awareness talks
preventive care discussions
lifestyle guidance

Recreational and Social Activities

group games
creative sessions
interactive challenges

These activities promote joy, connection and inclusion.

Inclusivity and Accessibility

Effective field days are:

inclusive of different age groups
adaptable for physical limitations
culturally sensitive
welcoming and non-competitive

Inclusivity ensures meaningful participation for all.

Why Monthly Frequency Works Best

Monthly scheduling:

maintains continuity
builds long-term trust
prevents disengagement
supports gradual relationship building

Consistency transforms engagement into culture.

Evidence Supporting Engagement Initiatives

Research shows that:

patient engagement improves health outcomes
staff wellbeing reduces errors and burnout
relationship-based care enhances satisfaction

Global health frameworks emphasise people-centred care models.

Measuring the Impact of Field Days

Impact can be evaluated through:

patient feedback
staff engagement surveys
participation rates
qualitative testimonials

Regular assessment helps refine the program.

Implementing a Successful Monthly Field Day

Key elements include:

leadership support
clear objectives
simple, inclusive activities
consistent scheduling
feedback-driven improvement

Success depends on commitment rather than scale.

Long-Term Impact on Healthcare Culture

Over time, Monthly Field Days contribute to:

stronger trust
improved communication
better morale
enhanced care experience

They reinforce the idea that healthcare is a partnership between people.

Conclusion

A Monthly Field Day with Patients & Staff is more than an engagement activity—it is a meaningful investment in trust, wellbeing and human connection. By creating shared experiences beyond clinical settings, healthcare organisations strengthen relationships that directly influence care quality and satisfaction. In an environment often driven by efficiency and outcomes, monthly field days remind us that compassion, communication and community remain at the heart of effective healthcare.
