THROUGHOUT the pandemic the University of Huddersfield’s Department of Pharmacy has been raising awareness on what vaccines are, how they are formulated, and why they’re an important part of the healthcare strategy as well as the progress on further developments in COVID vaccines, so that people can make an educated decision on becoming vaccinated or if choosing for their children. 

In response to the recent controversy about why COVID vaccines for children hadn’t been approved in the UK but had in the US and why the UK was so slow to respond, the department’s Dr Hamid Merchant has written an article explaining why we should not rush mass-immunising young children and how a delayed immunisation can be beneficial in offering a more suitable vaccine formulation for children, such as the nasal COVID vaccine that should be approved soon. 

“We shouldn’t rush with a one-size-fits-all approach, particularly when there is a product out there which would be of greater benefit to children.”

Dr Hamid Merchant

The article entitled, ‘Why COVID vaccines for young children (5–11 years) are not essential at this moment in time?’ and published in the Journal of Pharmaceutical Policy and Practice, agrees with the UK Government’s Joint Committee on Vaccination and Immunisation (JCVI) to not deliver a mandatory mass immunisation programme and explains why the current vaccines are not going to give the best outcomes in children in terms of efficacy and safety. 

“Often scientist and public health professionals fear that discussing these issues openly may undermine vaccine uptake,” said Dr Merchant, “but, it’s time that we explain the vaccine science and the differences between various vaccine formulations as a number of vaccine products are now approved by the regulatory agencies. We shouldn’t rush with a one-size-fits-all approach, particularly when there is a product out there which would be of greater benefit to children.”

The current situation

As matters currently stand the UK Government’s Joint Committee on Vaccination and Immunisation (JCVI) advises that COVID vaccines should be offered to 5–11-year-old children in the UK, but also deems such immunisation as non-essential. 

In the article, Dr Merchant, who is a pharmaceutical scientist with over 19 years of experience in pharmaceutical research and development both in industry and academia, explains why the Committee was so conservative in approving COVID vaccines for children and why its official statement on the matter took so long to be released.

 

He also talks about how there are a number of alternatives for children that are very close to being approved and which have been specially designed to achieve the outcomes in children that current vaccines cannot deliver. 

“We have tried to present a scientific explanation as to what vaccines are in general and how not every COVID vaccine is formulated the same,” said Dr Merchant. 

“During the early stages of the immunisation programme there wasn’t enough information available so by explaining how various vaccine formulations work and which ones are the safest considering an individual’s pre-existing medical conditions (personalised medicines), we are enabling the public to become more educated when deciding what to do for themselves, or for their children.” 

As the vaccines have now done their job of enabling the country to live with the virus, Dr Merchant believes it is imperative to continue investigating the next generation of COVID vaccines for all those who, in the future, still remain at high risk from emerging variants of concern.

“We have delivered a series of sessions and lectures for public and healthcare professionals alike to raise awareness of how various vaccines work, why they’re a very important part of the healthcare strategy as well as the current progress in COVID vaccines development.  This journal article is part of that campaign to increase medication safety amid a pandemic,” he said.

Sex work is real work: Global COVID-19 recovery needs to include sex workers

Societally, we need to recognize that sex workers have agency and deserve the same respect, dignity and aid as any other person selling their labour.

During the pandemic, business shifted from in person to work-from-home, which quickly became the new normal. However, it left many workers high and dry, especially those with less “socially acceptable” occupations.

The pandemic has adversely impacted sex workers globally and substantially increased the precariousness of their profession. And public health measures put in place made it almost impossible for sex workers to provide any in-person service.

Although many people depend on sex work for survival, its criminalization and policing stigmatizes sex workers.

Research shows that globally, sex workers have been left behind and in most cases excluded from government economic support initiatives and social policies. There needs to be an intersectional approach to global COVID-19 recovery that considers everyone’s lived realities. We propose policy recommendations that treat sex work as decent work and that centre around the lived experiences and rights of those in the profession.

Sex work and the pandemic

The United Nations Population Fund (UNFPA) recently reported that apart from income-loss, the pandemic has increased pre-existing inequalities for sex workers.

In a survey conducted in Eastern and Southern Africa, the UNFPA found that during the pandemic, 49 per cent of sex workers experienced police violence (including sexual violence) while 36 per cent reported arbitrary arrests. The same survey reported that more than 50 per cent of respondents experienced food and housing crises.

Lockdowns and border closures adversely impacted Thailand’s tourism industry which relies partially on the labour of sex workers.

In the Asia Pacific, sex workers reported having limited access to contraceptives and lubricants along with reduced access to harm reduction resources. Lockdowns also disrupted STI or HIV testing services, limiting sex workers’ access to necessary healthcare.

In North America, sex workers have been excluded from the government’s recovery response. And many began offering online services to sustain themselves.

Government vs. community response

Globally, sex workers have been left to fend for themselves during the pandemic with little to no support from the government. But communities themselves have been rallying.

Elene Lam, founder of Butterfly, an Asian migrant sex organization in Canada, talks about the resilience of sex wokers during the pandemic.

She says organizations like the Canadian Alliance for Sex Work Law Reform are working in collaboration with Amnesty International to mobilize income support and resources to help sex workers in Canada.

Organizations in the United Kingdom, Germany, India and Spain have also set up emergency support funds. And some sex worker organizations have developed community-specific resources for providing services both in person and online during the pandemic.

Global recovery needs to include sex workers

The International Labour Organization’s “Decent Work Agenda” emphasizes productive employment and decent working conditions as being the driving force behind poverty reduction.

Sociologist Cecilia Benoit explains that sex work often becomes a “livelihood strategy” in the face of income and employment instability. She says that like other personal service workers, sex workers also should be able to practice without any interference or violence.

In order to have an inclusive COVID-19 recovery for all, governments need to work to extend social guarantees to sex workers — so far they haven’t.

As pandemic restrictions disappear, it is crucial to ensure that everyone involved in sex work is protected under the law and has access to accountability measures.

Recommendations

As feminist researchers, we propose that sex work be brought under the broader agenda of decent work so that the people offering services are protected.

  1. Governments need to have a legal mandate for preventing sexual exploitation.

  2. Law enforcement staff need to be trained in better responding to the needs of sex workers. To intervene in and address situations of abuse or violence is critical to ensure workplace safety and harm reduction.

  3. Awareness and educational campaigns need to focus on destigmatizing sex work.

  4. Policy-makers need to incorporate intersectionality as a working principle in identifying and responding to the different axes of oppression and marginalization impacting LGBTQ+ and racialized sex workers.

  5. Engagement with sex workers and human rights organizations need to happen when designing aid support to ensure that an inclusive pathway for recovery is created.

  6. Globally, there needs to be a steady commitment towards destigmatizing sex workers and their services.

Despite the gradual waning of pandemic restrictions, sex workers continue to face the dual insecurity of social discrimination and loss of income support. Many are still finding it difficult to stay afloat and sustain themselves.

Societally, we need to recognize that sex workers have agency and deserve the same respect, dignity and aid as any other person selling their labour.

GSK and IQVIA launch platform of US vaccination data, showing drop in adult rates

Throughout the Covid-19 pandemic, the issue of vaccine uptake has been a point of contention, but a new platform from GSK and IQVIA is hoping to shed more light on vaccine data, via new transparency and general awareness.

The two companies have launched Vaccine Track, a platform intended to be used by public health officials, medical professionals and others to strengthen data transparency and display vaccination trends. According to the companies, the platform is intended to aid in increasing vaccine rates and will provide data on trends to assist public health efforts.

The platform will also allow users to identify vaccination trends for adults in the US across multiple vaccine types. Users will also be able to scan claims data nationally to track trends alongside pre-Covid metrics.

“For the first time, Vaccine Track brings quarterly data tracking and trends together in a comprehensive platform for immunization partners, decision-makers and stakeholders. Our goal for Vaccine Track is to support the return to pre-pandemic vaccination rates for adults and to go beyond by empowering the vaccine and public health community with frequently updated, actionable information to get ahead of disease together,” said Judy Stewart, GSK’s head of vaccines in a statement.

This move comes as vaccination rates in adults were already low even before the pandemic, with a CDC report stressing that vaccine coverage in adults was low across all age groups.

So far the platform’s data show a decline in adult immunizations, excluding flu vaccinations, across the country during the pandemic. The platform currently only has information from January 2019 to December 2021 on hand but will be updated every quarter.

The data itself observed that rates were especially low in minority populations, which were already showing lower rates of immunization pre-pandemic.

The platform also showed that national trends for adults aged 19 and older are still low, with an average decrease of 18% through last year in overall claims. Average monthly claims through 2021 for recommended vaccines were between 12% and 42% below 2019 rates, with nearly half of the states in the US facing greater than 30% reductions in overall claims for recommended vaccines from pre-pandemic levels.

In Medicare patients, the platform’s analysis found a more than 30% reduction in overall claims for recommended vaccines among Black and Hispanic populations between 2019 and 2021.

The information itself is sourced from medical claims data and longitudinal prescription data, the companies said.

Pfizer’s reported interest in acquiring sickle cell disease specialist Global Blood Therapeutics (GBT)  has been confirmed, with the $68.50-per-share deal valuing GBT at $5.4 billion.

As we reported this morning, the deal gives Pfizer already-approved SCD therapy Oxbryta (voxelator) – which industry watchers reckon could see a dramatic uptick in sales with Pfizer’s marketing muscle – plus a phase 3 antibody candidate, a phase 1 follow-up to Oxbryta that could offer improved dosing.

Oxbryta is the main asset in the deal, with Evaluate predicting sales could reach $1.5 billion in 2028 – a leap forward from the $195 million it made last year and $127 million in the first half of 2022.

Pfizer is expecting big things from the takeover , predicting that the company’s SCD franchise will bring in combined peak sales of more than $3 billion.

The boards of both companies have recommended the deal to shareholders, and the two companies suggested it should close before the end of the year – assuming of course it doesn’t fall foul of any antitrust issues raised by financial regulators.

The GBT deal comes at a time when the market for SCD therapies is undergoing significant change, with multiple new drugs reaching the market after years of stagnation and progress also being made with genetic therapies from the likes of bluebird bio, Vertex Pharma/CRISPR Therapeutics and Precision Bio/Novartis.

Oxbryta came to market in 2019, a few days after Novartis’ injectable anti-P-selectin antibody Adakveo (crizanlizumab), which is also tipped for blockbuster sales but like Oxbryta has suffered from a slow rollout.

CRISPR Therapeutics and Vertex are also in the running with their gene-editing candidate CTX001, in phase 1/2 trials which are due to generate final results later this year. If those results are positive the partners have said they could file for approval in the US before year-end.

Meanwhile, bluebird bio’s one-time gene therapy  lovotibeglogene autotemcel is supposed to be heading for regulatory filing in the US next year, although it has been delayed by an FDA partial clinical hold implemented after a persistent case of anaemia was seen in one adolescent patient in a clinical trial.

GBT’s inclacumab – another P-selectin antibody that could encroach on Adakveo – is in a pair of phase 3 trials due to generate results next year.

Meanwhile, there are a couple of orally-active pyruvate kinase R activators from Forma Therapeutics and Agios – etavopivat and mitapivat, respectively – in mid-stage development, and Pfizer has its own SCD candidate in PF-07209326, an E-selectin anatomist in phase 1.

It’s worth noting that this isn’t Pfizer’s first deal in SCD. In 2011 it paid $340 million for rights to rivipansel, a pan-selectin antagonist developed by GlycoMimetics, which failed a phase 3 test in 2019 and was jettisoned by Pfizer the following year.

The deal is another example of Pfizer splashing out on business development thanks to windfall cash generated by its COVID-19 vaccine Comirnaty and oral antiviral therapy Paxlovid. It comes shortly after the group closed a $6.7 billion acquisition of Arena Pharma, bringing on board etrasimod in late-stage testing for ulcerative colitis, and made an $11.6 billion takeover bid for Biohaven and its migraine therapy Nurtec ODT (rimegepant).
