New Delhi Apr 22 PTI Vaccine inequity remains an issue both within India where less than 2 per cent of the population has received a Covid booster and the globe with 56 countries unable to inoculate even 10 percent of their people says Johns Hopkins scientist Amita Gupta Tracking hospitalisation rates which provide an indicator of severity of illness is key the chief of the Division of Infectious Disease and Professor of Medicine at Johns Hopkins University School of Medicine said while stressing that no one is safe from Covid until everyone in the world gets vaccinated She cited the example of the Omicron variant to buttress her point The highly transmissible variant is believed to have emerged in November last year in South Africa and Botswana due to inadequate immunisation in African countries before spreading globally Gupta said adding that another variant is likely to follow the same trend Global vaccine inequity remains an issue both within India and globally For example in the continent of Africa less than 20 per cent of the population is currently vaccinated and there are countries in Africa still with less than 2 per cent vaccinated Gupta told PTI in an email interview As immunities wane and new Covid variants emerge it is more important than ever that communities are fully vaccinated and boosted she said It is not enough to fully vaccinate only a few countries Health workers and highest-risk populations in all countries must be fully vaccinated to stop the pandemic she added In India Gupta said there are some hard to reach areas and there is urgent need to increase booster vaccination for those who are eligible It is hard to predict whether further mutations in SARS-CoV-2 will increase or decrease the intrinsic virulence of the virus or the severity caused by it the public health expert said What we do know is that no one is safe from COVID-19 until everyone in the world is safe The vast majority of vaccines have been administered in high- and upper-middle-income countries Fifty-six countries have been effectively excluded from the global vaccine marketplace and have not been able to vaccinate even 10 per cent of their population she added A large densely populated country like India must ensure that the population has some measure of protection against severe disease -- either through immunization or previous infection As immunities wane and variants emerge Gupta said it is more important than ever that communities are fully vaccinated and boosted Less than 2 per cent of the population in India currently has received a Covid booster even though there is no shortage of supply This number needs to increase The cumulative number of COVID-19 vaccine doses administered in India crossed 187 crore on Wednesday according to the Union Health ministry The total number of precaution doses given to adults stands at 235786 23 lakh Going forward Gupta anticipates periodic increases in cases with new more transmissible variants Tracking hospitalisation rates is pivotal While some countries like the UK are seeing local increases in the number of cases hospitalisations are not increasing significantly and health systems are managing the increases Anticipate a similar situation will occur in India with these current sub variants It is possible that India could face another surge but will be better prepared as people are more aware systems have been strengthened and surveillance is ongoing she added The pandemic Gupta noted is still not over and it is difficult to predict when new variants will emerge and how these strains will behave We should continue close surveillance for early detection of Covid cases through existing surveillance networks in the country and be prepared to trigger recommendations to resume masking social distancing if and when surges occur she said According to the World Health Organization BA2 a more contagious Omicron sub variant is now driving most coronavirus cases around the world Gupta said the new variants are more transmissible than previous variants and an increase of cases is being observed Vaccines continue to protect against manifestations of severe disease Future morbidity and mortality depend on age demographics weariness to guidelines and vaccine and booster intake she said Global vaccinations and accurate disease surveillance will reduce the infection rate In India 73 per cent received the first dose 61 per cent two doses and 17 per cent received a booster as of April 13 so continuing to encourage the remaining population to get vaccinated is important Gupta explained Studies have shown that current Covid vaccines have had some reduction in efficacy in protecting people from infection and from developing severe disease with Omicron and its sub-variants Vaccines Gupta stressed are still reducing risk of severe disease in over 50 per cent of those who get the infection A lot of work is ongoing to prepare newer vaccines to optimise efficacy in preparation for additional new variants Many experts in the past have said that Covid in India was moving towards endemicity a stage when the presence of a disease becomes steady in a particular region or at least predictable There are three possible futures ongoing peaks of high disease and evolution of the virus with increased infection rate seasonal epidemic COVID-19 and endemic COVID-19 We are not yet at a place where we can say COVID is endemic Gupta explainedHer concerns come as India on Friday reported a single day rise of 2451 new Covid infections and 54 fatalities taking the countrys tally of cases to 43052425 over 43 crore and death toll to 522116 over 52 lakh For future pandemics Gupta said it is crucial to apply the lessons learned from Covid and invest in health infrastructure to better equip the country to prevent tragedy She said long-term investment and sustained commitment are needed for strengthening public health and healthcare systems and biomedical science in India The scientist noted that Johns Hopkins University has many different types of partnerships with India These include working together to fight infectious diseases and identifying new diagnostics treatments and prevention strategies for diseases such as TB HIV Covid dengue pneumococcal pneumonia and hepatitis India is a critical partner for addressing global public health challenges and we learn so much from each other in Indo-JHU health partnerships Gupta said We are working together on models of public health and medical training health systems strengthening biomedical discovery clinical research data science and development of low-cost accessible affordable technologies to improve the health of communities and individuals across the globe she added PTI

UN honours Henrietta Lacks, whose cells transformed medical research worldwide 

14-Oct-2021
For the past seven decades, the cells of Henrietta Lacks, a Black American woman who died of cervical cancer, have saved countless lives, and made numerous scientific breakthroughs possible, such as the human papillomavirus and polio vaccines, drugs for HIV treatment, together with cancer and COVID-19 research.   
This Wednesday, the UN World Health Organization’s () Director-General, Tedros Adhanom Ghebreyesus, recognized her world-changing legacy with a special award.    In 1951, while Ms. Lacks sought treatment, researchers took biopsies from her body without her knowledge or consent, and her cells became the first “immortal” cell line, now known as the “HeLa cells”.  

‘Reckoning’ with injustice 

Shockingly, as WHO points out, the global scientific community once hid her race and her real story, a historical wrong that Wednesday’s recognition hopes to help redress.  For Tedros, in honouring Mrs. Lacks, the UN agency “acknowledges the importance of reckoning with past scientific injustices and advancing racial equity in health and science.”  He said the award was also “an opportunity to recognize women, particularly women of colour, who have made incredible but often unseen contributions to medical science.” 

Legacy 

The award was received at the WHO office in Geneva by Lawrence Lacks, Ms. Lacks’ 87-year-old son.   He is one of the last living relatives who personally knew her. Mr. Lacks was accompanied by several of Henrietta Lacks’ grandchildren, great-grandchildren, and other family members.  Mr. Lacks said the family was moved to receive this historic recognition, honouring “a remarkable woman and the lasting impact of her HeLa cells.”  “My mother’s contributions, once hidden, are now being rightfully honoured for their global impact,” he said.   “My mother was a pioneer in life, giving back to her community, helping others live a better life and caring for others. In death she continues to help the world. Her legacy lives on in us and we thank you for saying her name – Henrietta Lacks.”   According to WHO, women of colour continue to be disproportionately affected by cervical cancer. The pandemic has also exposed the many health inequities that persist among marginalized communities around the world.  Studies in various countries consistently document that Black women are dying of cervical cancer at several times the rate of white women. Today, 19 of the 20 countries with the highest cervical cancer burdens are in Africa. 

Cervical cancer strategy 

The past year, which saw the 100th anniversary of Henrietta Lacks’ birth, also coincided with the launch of , an initiative Mrs. Lacks’ family has endorsed.   Her relatives have also joined WHO in advocating for equity in access to the HPV vaccine, which protects against a range of cancers, including cervical cancer.   Despite having been prequalified by WHO over 12 years ago, supply constraints and high prices still prevent adequate doses from reaching girls in low and middle-income countries.  As of 2020, less than 25% of low-income countries and less than 30% of lower middle-income countries had access to the HPV vaccine through their national immunization programmes, compared with more than 85% of high-income countries.  For the Assistant Director-General for Strategic Priorites and Special Advisor to the Director General, Princess Nothemba Simelela, “it is unacceptable that access to the lifesaving HPV vaccine can be shaped by your race, ethnicity or where you happen to be born.”  Reminding that the HPV vaccine was developed using Henrietta Lacks’ cells, she added: “We owe it to her and her family to achieve equitable access to this groundbreaking vaccine.” 

Remarkable Contribution  

As a young mother, Henrietta Lacks and her husband were raising five children near Baltimore when she fell ill.   She went to Johns Hopkins medical centre in the city, one of the few leading hospitals at the time which served African-Americans, after experiencing extensive vaginal bleeding and was diagnosed with cervical cancer.  Despite treatment, she died on October 4, 1951, at only 31 years old.  During treatment, researchers took samples of her tumour. That “HeLa” cell line was a scientific breakthrough: the first immortal line of human cells to divide indefinitely, under laboratory conditions, to power research.   The cells were mass produced, for profit, without recognition to her family. Over 50,000,000 metric tonnes of HeLa cells have been distributed around the world – forming part of over 75,000 studies.  In addition to the HPV and polio vaccines, they allowed for development of drugs for HIV/AIDS, haemophilia, leukaemia, and Parkinson’s disease; breakthroughs in reproductive health, including in vitro fertilization; research on chromosomal conditions, cancer, gene mapping, and precision medicine.  Currently, they are being used in studies responding to the COVID-19 pandemic. 

Teal tribute 

Following the presentation of the award, the family and WHO proceeded to the shores of Lake Geneva, to watch the city’s iconic Jet d’Eau illuminate in the colour teal, the colour which marks cervical cancer awareness.  It is the first of several world monuments that will illuminate in teal between now and November 17th, marking the first anniversary of the launch of the global elimination campaign.
