Vaccination or immunization is the injection of small amounts of weakened or killed bacteria and viruses, or their parts, to trigger an immune response and produce antibodies against that particular pathogen. The vaccine prepares the body to fight against the infection-causing organism when it actually enters the organism. This is classical vaccine development.
However, in more recent times, research has been focused on developing subunit vaccines that are more effective and defined. However, due to their synthetic nature, the immune response generated is weak. With the advent of COVID-19 and other complex pathogens like HIV and drug-resistant tuberculosis, there has been an increase in the challenges posed to the development of efficacious vaccines. Antigens susceptible to genetic mutations are another source of concern. In today’s population where immunity is compromised due to poor lifestyle and habits, it is all the more challenging to develop vaccines that deliver best results.
In this complex and trying time, Liposomal Nanotechnology has been gaining a lot of attention, especially in the field of vaccine development. It has been the subject of research ever since 1960, and has since then proven to be a profound, robust and stable novel drug delivery platform. The new, mRNA-based Covid 19 vaccine is a proven and strong example of a liposomal-based drug delivery system (lipid nanotechnology) being used to reach target cellular sites.

CONVENTIONAL LINEN IS ONE OF THE BIGGEST CULPRITS IN HOSPITAL ACQUIRED AS WELL AS SURGICAL SITE INFECTIONS
The ‘green colour’ linen is synonymous with hospitals, as it has been in use for centuries in hospitals world over, especially the conventional healthcare settings. But how many, even in the medical community, are really conscious about the responsibility for and the critical role of this piece of medical accessory in ensuring patient safety? Evidence from most hospitals in India indicates that not many are aware of the standards, and even if they are, not many bother with them. Again, going by real world experience, there exists another paradox. Though the actual cost of the repeated use of the linen is higher than the cost of single-use disposables (recommended in modernday care), it is still being used in a large majority of hospitals and clinics in India — because it is the convention. Therefore, transformation hesitance is more of a mindset issue rather than ignorance or economics. Most in the industry also oppose quality regulations in the country. In a market where hundreds of textile weavers and cloth merchants turned medical mask and accessory manufacturers overnight during the Covid pandemic, the market situation serves the unscrupulous minds who only eye the profits. However, there are a handful of local companies, besides the large organised players, who stick to quality products in this predominently price conscious market due to internal SOPs or pure commitment. For JAMES GEORGE, Founder and Managing Director at Kochi-based Careon Healthcare Solutions, it is more of a personal commitment. In a freewheeling interview with Editor CH UNNIKRISHNAN, George says that the primary reason behind the rise of unscrupulous players in the medical disposables market is lack of awareness among the users and the patients. Edited excerpts:
UK approves sotrovimab as new covid treatment for high risk adults
The Medicines and Healthcare Products Regulatory Agency (MHRA), the drug regulator of the UK, has approved sotrovimab, branded as Xevudy, a new biological drug to fight Covid-19. The drug was found effective to reduce the likelihood of hospital admission and death by about 79 percent in high-risk adults.
