As Health Care Systems reach Breaking Point  UG Alum Vidia Roopchand Provides Clues: Take  the Vaccine

As the  coronavirus continues to take its toll on  health and  welfare globally GOFAD, this week focuses on the situation in the Caribbean and a fascinating and informative presentation by Mr. Vidia Roopchand, UG Alumnus and lead COVID 19 Vaccine Researcher at Pfizer.
 
Background 
 
The seriousness of the situation in the Caribbean Region,  is best illustrated by recent decisions  taken by the political, education and  health authorities in the English, French and Spanish  Speaking Caribbean to postpone the start of the school year which is normally scheduled for the first two  weeks of September.  In view of the rising number of positive cases, the governments of Jamaica and Trinidad and Tobago have imposed lock downs and the doctors and nurses  in Guyana have initiated strikes  and sickouts against government mandates for the  vaccination of health workers.  In preceding blogs,  we referred to the suggested results of "nudges" combined with mandates as policies to combat vaccine hesitancy which contributes to much of the problem.  In the CARICOM Member states, vaccine hesitancy is compounded by the lack of adequate supply,  conflicting information and in some cases unscientific and fake news. The stark reality is demonstrated in the official figures  which  reveal the dramatic   health situation in the French Caribbean (Guadeloupe, Martinique and St Martin) in proximity to the Eastern Caribbean states,  with COVID deaths ranging from between 108-120 per 100,000. Suriname with 121 per 100,000 being the worst case scenario for CARICOM, while Guyana (71); St Lucia (56); Jamaica (51);  Barbados (49)  and Antigua and Barbuda (45)  are indicative of the challenges that are being presented.  At the same time, the Caribbean Public Health Agency  (the CDC of the Caribbean)  has illustrated that vaccination take  in the region is relatively low.  This partly due to lack of access and availability. Through the Caribbean Regulatory System (CRS), CARPHA apples its verification of vaccines safety based on the authorization  for emergency use  by the World Health Organization (WHO).  While countries are at liberty to undertake their own assessments of the quality, efficacy and safety of vaccines,   it is understandable  how vaccine hesitancy can be sustained especially in cases where vaccines are not duly authorized. 
 
It is under these circumstances that the University of Guyana hosted a virtual seminar on August 27th on  virology and the COVID Vaccines. It was presented by Mr. Vidia  Roopchand,  Principal Scientist for Vaccine Research and Development at Pfizer. He has been with the company for 28 years and spent his career supporting the efforts of the research and development team in formulating  innovative vaccines especially for immunization of children in Africa and including the research to develop the COVID-19 vaccine. He was particularly high in praise for the high quality of Education he received at the University of Guyana, graduating with a degree in Chemistry which was  the solid foundation for his professional development.   
 
 
The Fundamentals of Mr. Roopchand's  Presentation: This is a Great Time to Learn
 
Mr. Roopchand's  presentation illustrated how it was possible for Pfizer and other pharmaceutical companies to develop the respective COVID-19  vaccines. The ability to fast-track research and clinical trials for example, was a direct result of the worldwide cooperation as  the researchers  quickly mobilized to share their coronavirus data with other scientists;  made
advances in genomic sequencing based on previous  results of researchers that successfully uncovered the viral sequence of SARS-CoV-2.   Fast tracking was also facilitated by  numerous previous studies done since the Ebola outbreaks in  West Africa (2014).  As a result, WHO prioritized 11 pathogens  most likely to cause severe outbreaks in the near future.  In addition, research findings on  Hemorrhagic  Fever, Chikungunya, Zika and  respiratory syndrome coronavirus, all combined  and contributed to the quick turnaround of  results with respect to COVID -19.  See  The Lancet Global Health Trusted Source.
 
In the U.S., Operation warp Speed (OWS) was responsible for  fostering partnerships with multiple institutions including the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), to develop, manufacture, and distribute 300 million doses of vaccines.  By investing in multiple companies and vaccine platforms at once, OWS increased the odds of having a vaccine, or vaccines, available by the beginning of 2021. Simultaneously,  The European Commission also funded several vaccine candidates and worked with others in pledging $8 billion for COVID-19 research. The UK government Vaccine Taskforce was  a significant contributor to a wide variety of vaccine research. Its  funding helped develop the Oxford/AstraZeneca vaccine and the designers of this vaccine were the first to publish peer reviewed efficacy results.
 
Mr.  Roopchand provided a glimpse into the future of vaccine  research.  He describes himself as a "vaccine farmer",  stating categorically, “I’m from the developing world and I’ve seen what infectious disease can do.” He  proposes  to continue dissecting the data, to try and find other indicators of effective defenses. He indicated that  this involves a greater understanding of T cells  produced by the immune system to destroy virus-infected cells, and antibody-dependent cellular cytotoxicity (ADCC). This is, a specific immune response whereby a cell is covered in antibodies then destroyed by white blood cells, have largely been neglected in immunology research and  may play a significant role. His optimism is illustrated  in a  response to a question raised by Dr. Ulric Trotz,  one of his former UG Chemistry lecturers to whom he gives credit of his scientific beginnings.  “This is a great time to learn.”
 
An appreciation to Mr.  Roopchand given during the proceedings is worth quoting :
 
“ we salute you , grateful that you grace us with your wonderful presence and your bountiful gifts as a scientist with  roots that are riveted in the University of Guyana;  mindful that you help to shine a light so brightly on the University.   You are an exemplar of  the fact that  UG is the highest  and most recognized institution of higher education in Guyana  and the reason why we can aspire to be a world class university. As we approach the  60th anniversary  of the University in 2023, we look to you and others of your ilk to help to continue to forge partnerships, to attract endowments, to build a residential cadre of future graduates who aspire to your achievements but always remembering that we must help to build an institution that reaches back into the community, and whose research, teaching and practice  must continue to inspire young Guyanese and young people from this region to make meaningful contributions;  and like you,  make the world your stage for transformative change.  
 
Conclusions 
 
As we salute Vidia Roopchand, it is to be hoped that the lessons he presents and a multitude of suggested remedies that have emerged would help to inspire actions at the level  of CARICOM  where CARPHA, in this field, continues to play a vital role.  Especially aware of the upsurge in several variants and the evidence that the majority of hospitalizations and deaths from COVID are increasingly among the unvaccinated, there is need for adherence to the following among others:

  • Vigilance to stop the spread of COVID-19.
  •  Adherence to basic public health requirements: wearing a mass, washing hands and social distancing.
  • Recognition  that personal choices must not be at the expense of compromising the health and wellbeing of communities, countries  and the region.
  • Pay attention to reputable sources of information rather than conspiracy theories. 
  • Work on policies across party affiliation and on broad based technical cooperation and public-private partnerships. 
  • Recognition that health  and other front line workers are most at risk.
  • Pooling regional resources in the spirit of functional cooperation. 
  • Strive for higher levels of vaccinations. 
  • Engage mobile units geared to vaccinations uptake ensuring they  reach those differently abled. 
  • Increase support for those suffering from the ravages of natural disasters such as Haiti. 
  • Establish effective national and regional mechanisms  to  reach those in need. 
  • Avoid  the bureaucratic hurdles  that lead to Sludge (referred to in last week’s blog).
  • Develop Risk Management National and Regional Councils for broad guidance and  ensure all hands on deck .
 
In the final analysis, all creditable reports and scientific recommendations  point in the directions that taking the COVID -19 vaccination is the best insurance against  hospitalization and death.

Thank you for this information. I will pass it to my colleagues, to assist in encouraging others, to be vaccinated.
In addition to the specific information on vaccination, it highlights the parlous state of Healthcare Systems in the wider Caribbean Region, and the urgent need for improvement. By extension, the situation also applies to our Education Systems, but unfortunately, our Politicians/Leaders have neglected to prioritize these sectors for attention, to facilitate social and economic development.
Hopefully, this crisis and the resultant 'fallout,' will be the catalyst for change in the approach to governance and National Development.

Keep up the good work. Take care, and stay healthy.

Cyril.

Thanks for the article. Proud to say that I was almost the first in line on March 22 when the UWI Health/Aging and Wellness Centre began its very well organised "project". under the direction of Professor Denise Eldemire-Shearer.

I am now doing my best to influence the "less informed and the certainly misguided" to get the "jook". The outlook is not good here.

Peace and love..
